Definitions
- This invention relates generally to optoelectronic transceiver modules and in particular, it relates to an optoelectronic transceiver module, and its method of manufacture, whereby the module is inexpensive to manufacture, has a small yet robust package, and can be installed and replaced via a ribbon style connector for interchangeability and easy removal.
- Optoelectronic transceiver modules provide for the bi-directional transmission of data between an electrical interface and an optical data link.
- the module receives electrically encoded data signals which are converted into optical signals and transmitted over the optical data link.
- the module receives optically encoded data signals which are converted into electrical signals and transmitted onto the electrical interface.
- the transceiver is mounted onto one of the circuit card assemblies of a host computer, input/output system, peripheral device, or switch. Therefore, as with all electronic equipment, there is a need for a transceiver having an outer package design which occupies as little circuit card surface area as possible.
- transceiver module which is highly reliable and durable.
- One method presently used to ensure reliability and durability is to encapsulate the electronics of the transceiver within an insulative potting material. Encapsulating the transceiver electronics results in reducing vibration sensitivity and prevents unauthorized personnel from meddling with the module's electronics.
- the molding of the potting material around the transceiver electronics is performed by placing the electronics within a silicone mold. Any portion of the electronics which extends outside of the mold is caulked, by hand, with a silicone compound which provides for a liquid tight seal. Once the mold is sealed, potting material is inserted therein. After the potting material is allowed to cure, the silicone mold is peeled away from the newly formed module.
- the optoelectronic module is provided with a plurality of electrical pins for forming an electrical connection with a circuit card assembly.
- the electrical pins consist of solid wire strands with each pin having one end connected to the electronics within the module and the other end protruding from the module's potting material.
- each pin which protrudes from the potting material is either soldered within a plated through-hole, which is provided by the circuit card assembly, or placed within a connector which grasps onto the pin.
- the flimsy wire pins are very susceptible to deformation during both the normal handling of the module and its removal and installation onto a circuit card assembly.
- the flimsy pins currently used in the prior art are difficult and time consuming to attach to a circuit card assembly since they must be periodically inspected and realigned.
- the pins may break if they are realigned too many times.
- the module In addition to the electrical pins, the module also is equipped with two mounting ports for physically securing the module onto the circuit card assembly.
- the module is placed onto the circuit card assembly so that the mounting ports align with holes provided in the circuit card assembly. Once the module is properly aligned, screws are inserted through the holes in the circuit card assembly and into the mounting ports of the module. The screws are then tightened until the module is firmly affixed to the circuit card assembly.

Description
- This application is a continuation-in-part of U.S. Ser. No. 08/485,310, filed on Jun. 7, 1995, U.S. Ser. No. 08/417,914, filed on Apr. 6, 1995, and U.S. Ser. No. 08/372,780, filed on Jan. 13, 1995.
- This invention relates generally to optoelectronic transceiver modules and in particular, it relates to an optoelectronic transceiver module, and its method of manufacture, whereby the module is inexpensive to manufacture, has a small yet robust package, and can be installed and replaced via a ribbon style connector for interchangeability and easy removal.
- Optoelectronic transceiver modules provide for the bi-directional transmission of data between an electrical interface and an optical data link. The module receives electrically encoded data signals which are converted into optical signals and transmitted over the optical data link. Likewise, the module receives optically encoded data signals which are converted into electrical signals and transmitted onto the electrical interface.
- Normally, the transceiver is mounted onto one of the circuit card assemblies of a host computer, input/output system, peripheral device, or switch. Therefore, as with all electronic equipment, there is a need for a transceiver having an outer package design which occupies as little circuit card surface area as possible.
- In addition, there is a need for a transceiver module which is highly reliable and durable. One method presently used to ensure reliability and durability is to encapsulate the electronics of the transceiver within an insulative potting material. Encapsulating the transceiver electronics results in reducing vibration sensitivity and prevents unauthorized personnel from meddling with the module's electronics.
- Presently, the molding of the potting material around the transceiver electronics is performed by placing the electronics within a silicone mold. Any portion of the electronics which extends outside of the mold is caulked, by hand, with a silicone compound which provides for a liquid tight seal. Once the mold is sealed, potting material is inserted therein. After the potting material is allowed to cure, the silicone mold is peeled away from the newly formed module.
- The above described prior art molding process has several drawbacks. For example, it is time consuming and results in a transceiver module which has a pitted outer surface. In addition, the silicone mold used in the molding process has a limited life of only three to five modules before a new mold must be employed.
- The optoelectronic module is provided with a plurality of electrical pins for forming an electrical connection with a circuit card assembly. The electrical pins consist of solid wire strands with each pin having one end connected to the electronics within the module and the other end protruding from the module's potting material.
- The portion of each pin which protrudes from the potting material is either soldered within a plated through-hole, which is provided by the circuit card assembly, or placed within a connector which grasps onto the pin. However, the flimsy wire pins are very susceptible to deformation during both the normal handling of the module and its removal and installation onto a circuit card assembly. Thus, the flimsy pins currently used in the prior art are difficult and time consuming to attach to a circuit card assembly since they must be periodically inspected and realigned. Furthermore, the pins may break if they are realigned too many times.
- In addition to the electrical pins, the module also is equipped with two mounting ports for physically securing the module onto the circuit card assembly. The module is placed onto the circuit card assembly so that the mounting ports align with holes provided in the circuit card assembly. Once the module is properly aligned, screws are inserted through the holes in the circuit card assembly and into the mounting ports of the module. The screws are then tightened until the module is firmly affixed to the circuit card assembly.
- Similarly, to remove the module from the circuit card assembly, the screws must be removed and the wires either unsoldered from the circuit card or pulled from the connector which is a timely and expensive process requiring multiple components. In fact, it is common for the entire circuit card assembly to be changed in order to change the transceiver module or the media interface.
- Therefore, there is a need for a transceiver module which provides for a small, yet robust package, which is inexpensive to manufacture and can easily and quickly be installed and removed from a circuit card assembly in the field. The present invention is such an apparatus.

Extending perpendicularly from the mountingears connector shell 30. Theconnector shell 30 provides tworeceptacles 32,34 for receiving fiber optic connector plugs. Thereceptacles 32,34 are formed by theconnector shell 30 along with adivider wall 36 which extends along the center of the connector shell. Furthermore, located in the bottom 38 of eachreceptacle 32,34 is a keying channel 40,42 which extends toward thefirst end 16 of the main housing. - In the preferred embodiment, the
receptacles 32,34 of theconnector shell 30 are specifically dimensioned to receive an SC duplex plug. Therefore, the keying channels 40,42 ensure that an SC plug will be inserted so that receptacle 32 will only accept a plug for sending data andreceptacle 34 will only accept a plug for receiving data. - Extending from the
main housing 12 and into each of thereceptacles 32,34 is anoptical subassembly optical subassembly 44 is for sending transmissions over a data link and theoptical subassembly 46 is for receiving transmissions over a data link. In order to facilitate the connection between thetransceiver 10 and the data links, each optical subassembly has aferrule receiving portion 48,50.

However, in this alternative embodiment, another recess cover will be needed in order to prevent potting material from escaping the second end of the potting box. - Referring to FIG. 4, an enlarged perspective view of the optoelectronic module's
potting box 64 is depicted. Thepotting box 64 forms the outer housing of the optoelectronic module. Thus, the potting box generally has the shape of an oblong box with a rectangular bottom 72, twoparallel side walls first end wall 76, and an oppositesecond end wall 78. In a preferred embodiment, thepotting box 64 is injection molded of a polymer material such as VALOX, STANYL, or any other glass-filled heat resistent material which can withstand solder reflow temperatures. In addition, it is preferred that thepotting box 64 be either plated, wet plated, or vacuum metalized with an aluminum or stainless steel coating in order to dissipate an electrostatic discharge and provide for electromagnetic shielding. As well, the transceiver connector 20 (FIG. 1) may be plated, wet plated, or vacuum metalized, in order to reduce emissions and enhance grounding of the module. Such metalization of theconnector 20 can bring the module in compliance with FCC Rules, Part 15. In a preferred embodiment, theconnector 20 is metalized separately from thepotting box 64 so that each attachment portion is metalized and provides for conductivity between the parts. As theconnector 20 will be attached to a chassis containing fiber optic connectors which are at ground potential, the connector will ground themetalized potting box 64 which is attached to a daughter board. Such grounding enhances the module's ability to dissipate electrostatic discharge and provide for electromagnetic shielding. Thetransceiver connector 20 also includes agrounding clip 25 attached at theslot 23. - As previously indicated, all of the transceiver's

The bottom of therecess 84 has three flat mating surfaces 95 (only two of the mating surfaces are depicted in FIG. 4). - Correspondingly, referring to FIG. 5, a
recess cover 96 is depicted for placement within the recess located in the first wall of the potting box. Preferably, therecess cover 96 is made of the same material as the potting box and is either plated, wet plated, or vacuum metalized with an aluminum or stainless steel coating. - In FIG. 5, the
recess cover 96 has two semicircular through-ports ports guide beams - The recess cover96 firmly mounts within the recess of the potting box's first wall so that the mating surfaces 95 and 105 of both the
recess 84 and therecess cover 96 will abut each other. Therecess cover 96 includes three indentions 106 which allow the cover to be positioned around the location where thelatch members recess cover 96 there arealignment grooves - Referring back to FIG. 4, during the manufacture of the transceiver module the circuit board is placed in the
potting box 64 with the male ribbon connector protruding outside of the potting box and the circuit board's optical subassemblies protruding out of therecess 84 in thefirst wall 76. Theoptical subassemblies potting box 64 by the alignment guides 88,90 located within each through-port - Once positioned within the
potting box 64, the circuit board 60 is affixed by two screws which are mounted to the standoff columns 80 via the circuit board mounting ports 82. - Once the circuit board60 is secured within the
potting box 64, therecess cover 96 is mounted onto thefirst end wall 76. Therecess cover 96 is mounted by engaging itsalignment grooves recess cover 96 is slid into position, the cover's through-ports optical subassemblies potting box 64 and therecess cover 96, a liquid tight seal will be formed between thepotting box 64, therecess cover 96, and theoptical subassemblies recess cover 96 in place, potting material is injected within thepotting box 64 for encasing the circuit board 60. The time to mold the module by the above method is reduced by approximately 90% over the prior art molding process because no hand caulking is needed to form the liquid tight seal. - Finally, referring to FIG. 6, the connector shell20 (See FIGS. 1 & 2) is mounted onto the
first end wall 76 of thepotting box 64 after the potting material has cured. Alignment of theconnector shell 20 is provided by two mountingposts post 112 has abore 114 which facilitates the attachment of theconnector shell 20, by the use of the previously mentioned screws, onto thepotting box 64. - In an alternative embodiment, the
ribbon style connector 66 may protrude perpendicularly from thesecond end 18 of themodule 10 so that it can be connected to a circuit card assembly in a direction which is parallel to the direction of insertion of the optic plugs into the module's receptacles. However, in this alternative embodiment, another recess cover will be needed in order to prevent potting material from escaping the second end of the potting box. - Referring back to FIG. 1, the male
ribbon style connector 66 protruding from themodule 10 has a beam portion 116, made of insulative material, which extends perpendicularly across the length of the circuit board 60. The maleribbon style connector 66 also has afirst side 118, an oppositesecond side 120, and adistal end 122. Extending perpendicularly from the circuit board 60 on both thefirst side 118 and thesecond side 120 of the maleribbon style connector 66 are twenty-eightelectrical contacts 124. Eachelectrical contact 124 consists of a strip of conductive material which is affixed to the maleribbon style connector 66 and is electrically connected to the circuitry mounted on the circuit board 60. - Correspondingly, the male
ribbon style connector 66 couples to a femaleribbon style connector 126 which is mounted onto thecircuit card assembly 128. Referring to FIG. 7, an enlarged cut-away side view is shown of the femaleribbon style connector 126 taken along line 7-7 of FIG. 1. The femaleribbon style connector 126 has two parallel rows of twenty-eight (28) contact beams 130,130 contained within a contact chamber 132 (only one contact from each row is depicted). Eachcontact beam 130 is constructed of a flat strip of conductive metallic material. Furthermore, eachcontact beam 130 has afirst end 134, a seconddistal end 136, and a bend 138 which is located adjacent to the second end and extends toward the contact beam located in the opposite row. - The female
ribbon style connector 126 is mounted onto thecircuit card 128 such that thefirst end 134 of eachcontact beam 130 extends through the circuit card assembly. Likewise, thesecond end 136 of eachcontact beam 130 extends within a travel limitation slot 140 formed in the top 142 of the femaleribbon style connector 126. Each slot 140 provides abackstop 144, consisting of one of the connector's walls 146, and afrontstop 148. Correspondingly, contact beams 130,130 are positioned in the chamber 132 such that thesecond end 136 of eachcontact beam 130 resiliently urges against thefrontstop 148. - In order to provide access to the contact beams130,130 within the female
ribbon style connector 126, the top 142 of the connector has aslot 150 positioned between the two rows of contact beams. Correspondingly, in order to make an electrical connection between the femaleribbon style connector 126 and the male ribbon style connector 166 depicted in FIG. 1, thedistal end 122 of the male ribbon style connector is inserted within the female connector'sslot 150. As the maleribbon style connector 66 is pushed further within the female connector's chamber 132 the two rows ofcontact beams contact beam 130 will resiliently urge against a correspondingelectrical contact 124 mounted on the maleribbon style connector 66. Thus, an electrical connection will be formed between the male ribbon style connector'selectrical contacts - Similarly, to disconnect the male ribbon style connector's
electrical contacts male connector 66 is simply pulled from the chamber 132 of the female connector. Once the maleribbon style connector 66 has been removed from the chamber 132, the contact beams 130 of thefemale connector 126 will resiliently regain the configuration of FIG. 7, whereby thesecond end 136 of each contact beam will abut itscorresponding frontstop 148. - Turning to FIG. 8, an enlarged perspective view, along with a partial fragmentary view, is depicted of a resilient male ribbon style connector166. The connector 166 includes a
beam type housing 216 having afirst side 218, an oppositesecond side 220, and adistal end 222. The resilient male ribbon style connector 166 in FIG. 8 serves as another embodiment of the male ribbon style connector depicted in FIGS. 1-3 wherein the male connector in FIG. 8 is resilient and the male connector in FIGS. 1-3 is non-resilient.

contact beam 230 is constructed of a flat strip of conductive metallic material. Furthermore, eachcontact beam 230 has afirst end 234, a seconddistal end 236, and abend 238 which is located adjacent to the second end and extends away from the contact beam located in the opposite row. - The male ribbon style connector166 is mounted onto the module's
circuit board 260 such that thefirst end 234 of eachcontact beam 230 extends through the circuit board. In a preferred embodiment, thefirst end 234 of thecontact 230 is inserted within a through-hole of thecircuit board 260 which contains traces for providing an electrical connection from thecontact 260 to components mounted on the board. Likewise, thesecond end 236 of eachcontact beam 230 extends within a travel limitation slot 240 formed in the top 242 of the resilient male ribbon style connector 166. Each slot 240 provides a backstop 244, consisting of the connector'ssupport wall 246, and a frontstop 248. Corresponding, contact beams 230,230 are positioned such that thesecond end 236 of eachcontact beam 230 resiliently urges against the frontstop 248. - Access for making an electrical connection with the contact beams230,230 is provided since they protrude from the male ribbon style connector 166 in the area around the
bends distal end 222 of the male ribbon style connector is inserted within a slot provided by the female connector. As the male ribbon style connector 166 is pushed within the female connector, the two rows ofcontact beams contact beam 230 will resiliently urge against a corresponding electrical contact mounted within the female ribbon style connector. Thus, an electrical connection will be formed between the male ribbon style connector's electrical contact beams 230,230 and the female connector's contact beams. - Similarly, to disconnect the resilient male ribbon style connector166 from the female connector, the male connector is simply pulled from the female connector. Once the male ribbon style connector 166 has been removed, the contact beams 230,230 will resiliently regain the configuration of FIG. 9, whereby the
second end 236 of each contact beam will abut its corresponding frontstop 248. - An alternative embodiment of the present invention is shown in FIG. 10 having a
main housing 312, having afirst end 316 and asecond end 318. As discussed in the previous embodiments, thehousing 312 includes optical subassemblies for sending transmission over a data link and receiving transmissions over a data link. The preferred embodiment is an optoelectronic transceiver, however, a simplex transmitter or receiver or multiple transmitters or receivers may be incorporated in the module housing of the alternative embodiment. At thefirst end 316 is atransceiver connector 320 for receiving fiber optic plugs. In an alternative embodiment, optical fibers may be directly attached to the module and the optical subassemblies therein. At thesecond end 318 is apluggable connector 366. In the preferred embodiment, thepluggable connector 366 is a D-shaped connector having a printedcircuit board 368 having multiple contact traces 370 adhered thereto. Thetransceiver housing 312 is pluggable intoreceptacle 310 and is inserted into thereceptacle 310 in direction of arrow 300. Thereceptacle 310 includes areceptacle housing 370 having a top 372 andsides receptacle housing 370 includes anopen end 376 and aclosed end 378. At theclosed end 378 of thereceptacle housing 370 is aconnector 380 for mating with thepluggable connector 366. Theconnector 380 protrudes into the interior thereceptacle housing 370 and has an aperture for receiving thepluggable connector 366 of thetransceiver housing 312. In the preferred embodiment, theconnector 380 is a female connector for receiving themale connector 366. However in an alternative embodiment, thepluggable connector 366 of thetransceiver housing 312 may be a female connector and theconnector 380 of thereceptacle housing 370 would be a male connector. Protruding from theconnector 380 arecontacts 382 for direct connecting to a printed circuit board in a peripheral device such as a work station or computer to wire theconnector 380 directly to traces of a printed circuit board. In an alternative embodiment, a flat ribbon cable for transmitting the electrical signals protrudes from the transceiver module. Thereceptacle housing 370 includes insides aperture 384 for providing the locking of the transceiver within thereceptacle housing 370. - The
transceiver housing 312 includes a pair of release levers 350,351. The description ofrelease lever 350 is the same of that for 351. Therelease lever 350 includes a first end 353 which is attached to the side of thetransceiver housing 312. In a preferred embodiment, therelease lever 350 is integrally molded with thetransceiver housing 312. Therelease lever 350 includes asecond end 352 which includes agripping portion 355 which has lined edges to assist in gripping of therelease lever 350. Intermediate to the first end 353 and thesecond end 352 is anintermediate portion 354. Theintermediate portion 354 angles outwardly away from the sides of thetransceiver housing 312. Attached at the end of theintermediate portion 354 is thesecond end 352 which is generally parallel to the side of thetransceiver housing 312. However, as theintermediate portion 354 angles outward and away from the side of thetransceiver housing 312, thesecond end 352 is at a distance from the sides of thetransceiver housing 312 in its nonmated condition. Protruding from theintermediate portion 354 isdetente 360. Thedetente 360 includes anengagement surface 362. Upon insertion of thetransceiver housing 312 into thereceptacle 370, theintermediate portion 354 abuts against theside 374 of thereceptacle housing 370 and causes therelease lever 350 to compress inwardly toward thehousing 312. As thehousing 312 is further inserted within the receptacle, the engagingportion 362 abuts against thesidewall 374 of thereceptacle housing 370 causing therelease lever 350 to compress further. Upon further insertion, thedetente 360 engagesaperture 384 of thereceptacle housing 370 and therelease lever 350 snaps outwardly to engage theaperture 384. Upon snapping outwardly of therelease lever 350, thetransceiver housing 312 is fully mated within thereceptacle housing 370. In this fully mated position, thepluggable connector 366 is fully mated with theconnector 380 of thereceptacle housing 370. - For removal of the
transceiver housing 312 from thereceptacle housing 370, the release levers 350,351 are grasped at thegripping portion 355 of thesecond end 352 in order to compress the levers inwardly toward thetransceiver housing 312. The compression of the release levers 350 releases thedetente 360 from theaperture 384 of thereceptacle housing 370. Allowing thepluggable connector 366 of thetransceiver housing 312 to be removed from theconnector 380 of the receptacle housing and for theentire transceiver housing 312 to be removed from thereceptacle 370. - Turning to FIG. 11, a top view of the alternative embodiment of the transceiver of the present invention is shown mated within a receptacle. The
transceiver housing 312 is mated withinreceptacle housing 370. The release levers 350,351 are compressed within thesidewalls receptacle housing 370. Thedetentes 360,361 of the release levers 350,351, respectively, are seated within theapertures 384,385. In the fully mated position, thepluggable connector 366 is mated with theconnector 380 of thereceptacle housing 370. It can be seen that in order to release thetransceiver housing 312 from thereceptacle 370, the grippingportions receptacle housing 370 and may be grasped between two fingers and compressed together in order to release thedetentes 360,361 from theapertures 384,385 and to then release the transceiver from the receptacle. - Still referring to FIG. 11,
transceiver connector 420′ is shown attached to thefirst end 316 of thetransceiver module housing 312. In this alternative embodiment, thetransceiver connector 420′ may have an electrical connection and receive electrical plugs. As an alternative to thetransceiver connector 320 shown in FIG. 10 which was described to receive fiber optic plugs, thetransceiver connector 420′ of FIG. 11 may receive electrical plugs. For example, a copper wired electrical connector may be inserted in thetransceiver connector 420 having a receptacle opening for receiving the electrical plug therein (see also FIG. 12). In the alternative embodiment, the coppertransceiver module housing 312 will not have optical subassemblies mounted therein. However, an electrical subassembly for the transceiver described above is still contained within the transceiver module, such as a transformer or other AC coupling means and differential (balanced) or single ended (unbalanced) transmission line drive and receive circuits. By providing atransceiver module 312 which supports different types of media in a common housing design, the transceiver module may be easily upgradable in the field. For example, an initial installation of an optical transceiver module (as shown in FIG. 12) having multi-mode capabilities could provide transmission distances of approximately 500 meters. Should the system be reconfigured so that the required transmission distances decrease to 20 to 30 meters, the multi-mode optical transceiver could easily be replaced with a less costly copper transceiver (as shown in FIG. 11) using the removable housing of the present invention. Such an operation can be easily accomplished by a technician in the field due to the easily disengageable latching means 350 and thepluggable connector 366 of thetransceiver housing 312 and other features of the present invention discussed herein. Additionally, further upgrades may be accomplished in later reconfigurations that may require transmission distances of up to 10 kilometers by replacing the transceiver module with an optical transceiver module of the present invention having single-mode capabilities. - Referring to FIG. 12 a copper transceiver as discussed above is disclosed. The
transceiver module housing 412 includesfirst end 416 andsecond end 418. Running between the first and second end along the sides of thetransceiver housing 412 arerails second end 418 of the transceiver housing is inserted into a receptacle assembly, such as shown in FIGS. 14-17, andpluggable connector 466 provides electrical connection to the receptacle assembly and a motherboard. Thefirst end 416 includes a latch cover 490 to latch thetransceiver housing 412 to the receptacle assembly, as discussed in more detail below. The latch cover 490 also includeslatch member 496. Mounted at thefirst end 416 are a pair oftransceiver connectors 420. In the embodiment of FIG. 12 the transceiver connectors are copper connectors for receiving electrical coaxial cable such as an SMA connector. - Turning to FIG. 13, an enlarged perspective view of the
second end 418 of thetransceiver housing 412 is disclosed. Thepluggable connector 466 or male ribbon style connector includes a D-shapedshroud 480 encircling aninsulative substrate 460 such as a circuit board. Thecircuit board 460 protruding from thetransceiver housing 412 has afirst side 421, an oppositesecond side 422, and adistal end 440. Extending perpendicularly from thesecond end 418 of thetransceiver housing 412 iscircuit board 460 having affixed on both thefirst side 421 and thesecond side 422 twenty electrical contacts 424. Each electrical contact 424 consists of a strip of conductive material which is affixed tocircuit board 460 and is electrically connected to the circuitry mounted on thecircuit board 460 within thetransceiver module 412. Thefirst side 421 of thecircuit board 460 includes ten electrical contacts 424 affixed thereto. As shown in FIG. 13 the electrical contacts are numbered 1 through 10. The first and tenth contact adjacent the side edges of thecircuit board 460 are ground contacts 425. The ground contacts 425 extend out to thedistal end 440 of thecircuit board 460. The remaining contacts, two through nine, are off-set from thedistal end 440 of thecircuit board 460. This arrangement of the ground contacts 425 protruding further than the electrical contacts 424 allows for the hot plugging of thetransceiver module 412 to a receptacle assembly which is already operational and powered up. The ground contacts 425 will make electrical contact with the receptacle assembly prior to the electrical contacts 424, allowing the transceiver module to reach the ground potential of the receptacle assembly before the electrical contacts 424 are connected to the receptacle assembly. This arrangement provides a common ground in order to dissipate static discharge to ground potential prior in sequence to connection of other electrical contacts 424. Thesecond side 422 of thecircuit board 460 may also have an arrangement similar to thefirst side 421 of thecircuit board 460 in order to provide grounding for hot plugging. - Turning to FIG. 14, a further alternative embodiment of the present invention is shown. In the further alternative embodiment, pluggable transceiver housings511,512 provide for a pluggable transceiver. However, the pluggable transceiver housings 511,512 have an alternative embodiment to the release levers 350,351 as shown in FIGS. 10 and 11. The transceiver housings 511,512 include a
cover latch receptacle assembly 500. FIG. 14 shows transceiver housing 512 partially mounted to areceptacle assembly 500. Transceiver housing 511 is shown fully mated to thereceptacle assembly 500. Thereceptacle assembly 500 includes a motherboard orcircuit card assembly 528, a mountingpanel 570 adjacent and perpendicular to a front side and attached to themotherboard 528, mountingrails 571,572 and a circuit card connector 580 attached toconnector bracket 582 which is mounted to themotherboard 528. These elements of thereceptacle assembly 500 may also define a housing of a device such as a host computer, server or PC. The elements described relating to the transceiver housing 512 are also included for the transceiver housing 511, but will not be separately identified in order to avoid redundancy. - Transceiver housing512 includes a
first end 516 having atransceiver connector 520 attached thereto. In a preferred embodiment, thetransceiver connector 520 receives optical plugs such as a duplex SC fiber optic connector. However, in an alternative embodiment, as discussed above, thetransceiver connector 520 may provide an electrical connection by receiving an electrical plug having copper wires. However, in the case where thetransceiver connector 520 receives fiber optic plugs, thereceptacle openings transceiver connector 520 is mounted to atransceiver housing frame 550. In a preferred embodiment, thetransceiver connector 520 and thetransceiver frame 550 are integrally molded of a polymer material. Thetransceiver frame 550 may also form a potting box as discussed above. Mounted at asecond end 518 of the transceiver housing 512 is apluggable connector 566. In a preferred embodiment, theconnector 566 is a D-shaped connector as discussed above (FIG. 13). Thepluggable connector 566 being oriented at thesecond end 518, opposite thefirst end 516 of the transceiver housing 512, allows for the quick and easy insertion of the transceiver housing 512 into thereceptacle assembly 500 and for pluggably mating the transceiver housing 512 to the circuit card connector 580 of thereceptacle assembly 500 all in a single motion. Thetransceiver housing frame 550 is received byguide rails 571,572. The guide rails 571,572 includedetentes 573 for guiding thetransceiver housing frame 550 and maintaining the transceiver housing 512 in a parallel orientation to themotherboard 528 and for aligning thepluggable connector 566 to the circuit card connector 580. - Upon insertion of the transceiver housing512 within the
receptacle assembly 500, approximately three quarters of the way, thelatch cover 590 securedly mounts the transceiver housing 512 to thereceptacle assembly 500. Thelatch cover 590 includes afirst side 591 and a second side 592. The second side 592 of thelatch cover 590 is hingedly attached to thefirst end 516 of the transceiver housing 512. An attachment means 593 attaches thelatch cover 590 so that it swings in a transverse direction to thefirst end 516 of the transceiver housing 512 in direction of arrow 599. The second side 592 of thelatch cover 590 also includes aboss 595. Upon insertion of the transceiver housing 512 into thereceptacle assembly 500 and initial rotation of the latch cover in direction of arrow 599, theboss 595 will catch on the mountingpanel opening 574. Theboss 595 engages the backside of the mountingpanel 570 and pushes the transceiver housing 512 toward its completely mated orientation within thereceptacle assembly 500. As thelatch cover 590 is rotated in direction of arrow 599, it is moved into an orientation so that it is almost parallel with the front surface of the mounting panel so thatlatch member 596 engages theopening 574 of the mountingpanel 570. Thelatch member 596 is attached toresilient beam 597 attached to thefirst side 591 of thelatch cover 590. Upon engagement of thelatch member 596 with theopening 574, theresilient beam 597 is compressed toward thefirst end 591 of thelatch cover 590. Thelatch cover 590 is then moved to its fully latched position and the resilient beam 592 springs outwardly so that thelatch member 596 engages the back of the mountingpanel 570. Thelatch member 596 may be released from its latched position by depressing therelease lever 598 attached at the end of theresilient beam 597. In a preferred embodiment, thelatch cover 590,latch member 596,resilient beam 597 andrelease lever 598 are integrally molded of a polymer material. - In an embodiment of the transceiver housing512, the
latch cover 590 may be metallized and the mountingpanel 570 also metallized or made of a metallic material and grounded, so that attachment of the transceiver housing 511,512 to the mountingpanel 570 via the metallizedlatch cover 590 automatically grounds the transceiver housings 511,512. - Turning to the transceiver housing511 shown fully mated with the
receptacle assembly 500 in FIG. 14, thelatch cover 590′ is shown fully latched to the mountingpanel 570 so that the front surface of thelatch cover 590′ is parallel to the front plane of the mountingpanel 570. Thelatch cover 590′ includeswindow 594 from which thetransceiver connector 520 protrudes. Upon fully mounting of the transceiver housing 511 within thereceptacle assembly 500 and the complete latching of thecover latch 590′, plugs may be inserted into thetransceiver connector 520′. In many circumstances, the transceiver housing 511 can remain within thereceptacle assembly 500 for a long period of time and in some cases, the transceiver housing 511 may never need to be replaced or removed. However, in certain circumstances, the transceiver housing 511 may need updating or repair. The present design allows for the easy removal and reinsertion of the transceiver housing 511. For example, the transceiver housing 511 may need to be modified so that a different mediainterface transceiver connector 520′ may be utilized and added to the housing. Or in another instance, the functioning of the transceiver module may need to be updated by adding a new chip set or optoelectronic subassembly. By depressing therelease lever 598′ thelatch cover 590′ may be unlatched and rotated to an “open” position. Once thelatch cover 590′ is “open,” thelatch cover 590 may be gripped and used as a handle to aid in pulling the transceiver housing 511 from thereceptacle assembly 500. Once removed, the transceiver module housing 511 may then be repaired, replaced or updated. - Turning to FIGS.15-16, a further alternative embodiment of the present invention is shown. Generally, FIGS. 15-16 show a new and improved receptacle for receiving a transceiver module, such as those described herein. For example, the
receptacle 310 disclosed in FIG. 10 is more clearly illustrated by reference to FIGS. 15-16. Similarly, the receptacle shown in FIGS. 15-16 is configured to receive thetransceiver housing 312 shown in FIGS. 10-11. A receptacle assembly 600 is shown in FIG. 15 having amotherboard 628 and a mountingpanel 670 having mounted thereto atransceiver receptacle 610. Thereceptacle 610 has afirst end 616 having anopening 676 and asecond end 618 having aconnector 680 adjacent thereto. Thetransceiver receptacle 610 also includes top 672 andsides - The walls of the
receptacle 610 define achamber 620. FIG. 15 is partially cut-away to expose thechamber 620 within thereceptacle 610. Mounted within thechamber 620 are ground surfaces ortabs ground tabs chamber 620 and are oriented to abuttingly engage or wipe against the external surfaces of a transceiver module mounted within thereceptacle 610. The outer surfaces of a transceiver housing are metallized so that upon insertion within thechamber 620 and engagement with theground tabs ground tabs motherboard 628. Theground tabs brace 695. Theground tabs brace 695 via arms 696,697. The arms 696,697 and thebrace 695 in a preferred embodiment are insert molded within thereceptacle housing 610. The insert molding is controlled so that only theground tabs chamber 620 and the ground posts 693,694 protrude out from the bottom of thereceptacle 610. - The
receptacle connector 680 includescontacts 682 which are attached to themotherboard 628. Protruding into thechamber 620 from theconnector 680 isreceptacle connector 681 for receiving the D-shaped connector at the end of the transceiver module inserted within thereceptacle 610. (See FIG. 10.) - Turning to FIG. 16, a side elevation cut-away view of FIG. 15 taken at line16-16 is shown. The
receptacle housing 610 is shown mounted to themotherboard 628 and the mountingpanel 670.Ground clip 692 protrudes into thechamber 620 and grounds the metallized transceiver housing to themotherboard 628. Theground tab 692 is attached to arm 697. Protruding from the arm 697 is groundpost 694 which is mounted within the plated through hole ofmotherboard 628 and is secured to the motherboard withsolder 629 and provides for grounding to the motherboard. At least a portion of the arm 697 and a portion of theground post 694 and brace 695 are molded within the polymer material of thereceptacle housing 610.Receptacle connector 680 is attached at thesecond end 618 of thereceptacle 610. Attached to thereceptacle connector 680 is D-shapedreceptacle 681 andcontacts 682. - Turning to FIG. 17 an alternative embodiment is provided where the receptacle assembly700 includes a circuit card assembly or
mother board 728, a mountingpanel 770, mountingrails 771, 772 and a circuit card connector 780 attached toconnector bracket 782. Mounted to the mountingpanel 770 is aprotective door 750. The mountingpanel 770 is partially broken away to more clearly show thedoor 750. Thedoor 750 is hinged at a point at the top of thedoor 750.Post 751 protrudes from the edge of the door and is received by an aperture in the mountingpanel 770. Mounted on thepost 751 is aresilient member 752 such as a spring. Thespring 752 is configured in order to return thedoor 750 to its closed position parallel to the front face of the mountingpanel 770 after thedoor 750 has been opened. Theprotective door 750 acts as a shield in order to limit electromagnetic radiation from escaping from the receptacle assembly 700 when the receptacle assembly 700 is empty. Certain power sources and components mounted to themotherboard 728 may develop electromagnetic emissions. In absence of a door such as 750 upon removal of a transceiver module from the receptacle assembly 700, the electromagnetic emissions generated by the components mounted on themotherboard 728 would be free to escape through theopening 776. Attachment of theprotective door 750 to the mounting panel inhibits these emissions. Theprotective door 750 may be metal or metallized in order to further reduce such emissions. Also by incorporation ofdoor 750 to the receptacle assembly 700 the receptacle may be left empty upon initial construction of the receptacle assembly 700, allowing for assembly of multiple receptacle assemblies 700 onmotherboard 728 for reception of additional transceiver modules at a later date. Thepost 751 provides for a hinge to thedoor 750 and allows for the swinging motion of the door. Thedoor 750 is hinged so that upon abutment of a transceiver module against the door and attempted insertion of the transceiver module throughopening 776, the door will swing inwardly allowing the transceiver module to be inserted therein. While the transceiver module is housed within the receptacle assembly 700 thedoor 750 will remain in an upright position adjacent the top of the transceiver module. Upon removal of the transceiver module from the receptacle assembly 700, thespring 752 causes thedoor 750 to swing back to its closed position parallel to the front face of the mountingpanel 770. - Turning to FIG. 18, another alternative embodiment of the present invention is shown. Attached to the
transceiver housing 811 is atransceiver connector 820 which is an alternative embodiment of thetransceiver connector 520 of transceiver housing 512 of FIG. 14. Thetransceiver connector 820 is shown having amodular port 821. Themodular port 821 is configured so that any number of receptacle connectors may be inserted therein for receiving various types of plugs. Due to the easily removable nature of thetransceiver module 811, the transceiver can be removed so that a plug receptacle (not shown) mounted within themodular port 821 may be removed and disconnected from the components within thetransceiver module 811 and a new plug receptacle inserted within themodular port 821 and connected to the components of thetransceiver module 811. Such an operation is best accomplished by the manufacturer using this orientation to achieve quick assembly and just-in-time manufacture and to avoid remolding of the entire module housing. Thetransceiver module 811 can then be easily reinserted and attached to the receptacle assembly 800. For example, thetransceiver module 811 may be configured for transmitting and receiving electrical signals from an external device having an electrical plug inserted into thetransceiver connector 820, as discussed above. Such a copper plug would be inserted into a copper plug receptacle which is mounted within themodular port 821. For example, a DB-9 connector may be used. In another embodiment, an alternative fiber optic receptacle could be inserted within themodular port 821. For example, a multiple channel connector such as an MT connector could be attached to thetransceiver housing 811 by inserting an updated optical fiber receptacle within themodular port 821 of thetransceiver connector 820 to receive a multi-channel connector. - In another embodiment, a media transducer may be inserted within
modular port 821. The media transducer may include at a first end a connector receptacle such ascoaxial connector 420 of FIG. 12 or anSC duplex connector 520 of FIG. 12. A second end of the media transducer may include an optoelectronic subassembly such as a PIN diode, laser diode such as LED and other optical circuitry for optical media; or an electrical subassembly such as a transformer or other AC coupling means for copper media. In another embodiment, the media transducer may include only a connector receptacle or only an optoelectronic or electronic subassembly. Such a media transducer would allow for the updating or changing of the media interface by removing the media transducer from themodular port 820 and replacing with another media transducer. - It should be understood that in describing the top and bottom portions of the transceiver module and its respective potting box components, the terms “top” and “bottom” are used by way of example only due to the orientation of the drawings. It should also be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Furthermore, although the transceiver module depicted in the presently preferred embodiment has its male ribbon style connector extending from the bottom, it should be understood from the outset that the connector can be configured to extend, for example, from the second end of the transceiver. Therefore, changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. Thus, it is intended that such changes and modifications be covered by the appended claims.
