DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates generally to optoelectronic transceiver modules and, more particularly, to low cost of module fabrication, having a small and robust package, and mounting and replacing via ribbon connectors for compatibility and ease of removal. The present invention relates to an opto-electronic transceiver module and a method of manufacturing the same, which provides electrostatic discharge and can be attached and replaced via a ribbon connector.

[0002]

BACKGROUND OF THE INVENTION Optoelectronic transceiver modules provide bidirectional transmission of data between an electrical interface and an optical data link. The module receives the electrically encoded encoded data signal, which signal is converted to an optical signal and transmitted over an optical data link. Similarly, the module receives an optically encoded encoded data signal, which is converted to an electrical signal and transmitted to an electrical interface.

Typically, a transceiver is mounted on one of a circuit card assembly consisting of a host computer, an input / output system, peripheral devices, or a switch.
Therefore, like all electrical devices, transceivers are required to have an external package design with as little circuit card surface area as possible. Furthermore, transceiver modules are required to have high reliability and durability.
One approach currently used to ensure such reliability and durability is to embed the transceiver electronics in an insulating encapsulant. By enclosing the electronic components of the transceiver, the sensitivity of the vibration can be reduced, and unauthorized persons can be prevented from touching the electronic components of the module.

[0004] Today, the molding of the surrounding material surrounding the electronic components of the transceiver is performed by placing the electronic components in a silicon mold. Any part of the electronic component that protrudes outside the mold is manually closed (caulked) with a silicon compound that provides liquid seal resistance. Once the mold is sealed, potting material is placed therein. After the surrounding material has been cured, the silicone mold is stripped from the newly formed module.

[0005] The molding process in the prior art described above has several disadvantages. For example, it is time consuming, resulting in depressions on the exterior surface of the transceiver module. Further, in the silicon mold used in the molding process, the number of modules that can be molded in one mold is limited to three to five unless the mold is replaced with a new mold.

[0006] The optoelectronic module is provided with a plurality of electrical pins for making an electrical connection with a circuit card assembly. Such electrical pins consist of solid wire strands, one end of each being connected to the electronics of the module and the other end projecting from the molded enclosure material. The portion of each pin protruding from the surrounding material is located in a connector that can be soldered or fitted into a plated through-hole provided in the circuit card assembly. However, due to the weakness of the wire pins, they are very susceptible to deformation during general handling (handling) and attachment / detachment to circuit car assemblies. Thus, the fragile pins used in the prior art are difficult and time consuming to attach to a circuit card assembly because they must be periodically inspected and reassembled. Further, such pins can be broken as they are reassembled too many times.

In addition to the electrical pins, the module is equipped with two mounting ports for mounting itself on the circuit card assembly. The module is placed on the circuit card assembly and its mounting ports are aligned with holes provided in the circuit card assembly. When the module is correctly positioned, screws are inserted through holes in the circuit card assembly and into the mounting ports on the module. Such screws are tightened until the module is firmly secured to the circuit card assembly.

Similarly, when removing the module from the circuit card assembly, the screws must be removed and the wires must be separated from the circuit card assembly or disconnected from the connector, which requires a number of components. It is a timely and expensive process. In fact, it is common to replace the entire circuit card assembly to change the transceiver module or intermediate interface.

[0009] Finally, when the module is secured to the circuit card assembly, the optical fiber containing the SC double plug connector is coupled to the module. In general,
The SC double plug connector has a plastic housing that can be charged electrostatically. Thus, its connection to the transceiver module can damage the module's electrical components unless the SC connector is properly grounded.

Those skilled in the art should recognize that the potential for damage from electrostatic discharge is not limited to transceiver modules coupled to SC duplex connectors. Other opto-electronic modules, such as Gigabo Link Module (GLM)
Are susceptible to damage by electrostatic discharge whenever they are mated to a connector containing optical fibers. Therefore, the transceiver module consists of a small and robust package, has a low manufacturing cost, and can be easily and quickly attached to and detached from a circuit card assembly in a place where an electrostatic discharge occurs, and also easily and quickly. It is required that it can be attached to and detached from a circuit card assembly. The invention relates to such a device.

[0011] Similarly, there is a need to prevent electrostatically charged fiber optic connectors from damaging electrical components within the optoelectronic module.

[0012]

SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide a small transceiver module package. It is another object of the present invention to provide a module package that is robust and prevents tampering.

It is another object of the present invention to provide a module which can be quickly attached to and detached from a circuit card assembly. It is another object of the present invention to provide a module package that can be produced quickly and easily. A further object of the present invention is to provide a module package that can be produced at low cost.

It is a further object of the present invention to prevent the electrostatically charged connector from damaging the electrical circuitry of the optoelectronic module by pre-grounding the plug connector. It is a further object of the present invention to provide a module with a coating that dissipates electrostatic discharges and acts as an electromagnetic field.

It is a further object of the present invention to provide a module that can be easily and quickly connected to and removed from a housing. It is another object of the present invention to provide a receptacle for receiving a module having grounding means.
Another object of the present invention is to provide a receptacle provided with means for preventing leakage of electromagnetic radiation from the receptacle.

It is a further object of the present invention to provide a transceiver module that can be replaced to provide electrical or fiber optic connections.

8, 50 are connected to the SC plug. Further, the transceiver latch members 52, 54, 56 and 58 firmly hold the SC plug in contact with the connector 20.

The actual transmission and reception of optically encoded data is accomplished by a laser diode in optical subassembly 44 and a photodiode in optical subassembly 46. The laser diode and the photodiode are both electrically connected to a circuit board mounted in the main housing 12. FIG. 1 shows a part of the circuit board 60. Integrated on the circuit board 60 is a circuit structure (not shown) for transmitting and receiving optically encoded data. The circuit board 60 is
It is covered by an enclosing material 62 and an enclosing box 64 forming the main housing 12. The surrounding material 62 covers the circuit board 60 so that only the male ribbon connector 66 of the circuit board extends from the surrounding material 62.

In addition, the enclosing box 64, including the latch members 52, 54, 56 and 58, may be plated or wet plated or vacuum metallized with an aluminum or stainless steel coating to dissipate the electrostatic discharge and provide an electromagnetic shield. (Metal coating). Similarly, the transceiver connector 20 (see FIG. 1) may be plated or wet-plated to reduce emitted electrons (emissions) and increase grounding of the module.
Alternatively, it may be vacuum metallized. Such metallization of the connector 20 allows the module to comply with Part 2 of the FCC Rules. In the preferred embodiment, the connector 20 is metallized separately from the enclosing box, so that each mounting is metallized and electrical conductivity between the parts is provided. When the connector 20 is attached to a chassis including an optical fiber connector in a ground potential (ground potential) state, the connector 20 is attached to a daughter board (daug).

I have. Therefore, the transceiver module 10 can be mounted inside the computer chassis 310 with the outwardly projecting connector 20 for easy access from outside the chassis.

Correspondingly, when transceiver module connector 20 is positioned within connector port 312, tabs 27, 29 press against connector port sides 314,316. As a result, the tabs 27 and 29 are electrically connected to the computer chassis, so that the transceiver module connector 20 is grounded.
