Abstract
A robust optoelectronic transceiver module which is quick, easy, and inexpensive to manufacture. The transceiver module has a main housing which consists of a circuit board having an optical subassembly mounted thereon. The module housing may be pluggable via a retention member received within the receptacle. The module and receptacle assembly may include grounding member such as a ground clip mounted within a gap provided between the module and a connector port of the receptacle to limit electromagnetic emissions.
Claims41
A transceiver module and receptacle assembly comprising:
- a transceiver module housing having a first end and a second end;
- a circuit board mounted within the housing and an optical subassembly electrically connected to the circuit board;
- a pluggable male ribbon style electrical connector at the second end connected to said circuit board and protruding from said housing for quickly installing and replacing said module to or from a circuit card assembly and the male ribbon style connector having at least a pair of metallic fingers extending from said housing on opposed sides of an insulator;
- a conductive portion of the housing to provide for electromagnetic shielding;
- and
- a grounding means associated with the receptacle and providing an electrical connection between the receptacle and the conductive portion of the housing in order to ground the module and enhance the electromagnetic shielding.
A transceiver module comprising:
- a transceiver module housing having a first end and a second end;
- a circuit board mounted within the housing and a transmitting subassembly electrically connected to the circuit board;
- a release lever mounted to the transceiver module housing adjacent the first end and a pluggable male ribbon style electrical connector at the second end connected to said circuit board and protruding from said housing for quickly installing and replacing said module to or from a circuit card assembly;
- the housing including an external conductive surface shielding a portion of the module;
- and
- a ground member electrically connected to the conductive surface in order to reduce electromagnetic interference and provide for an FCC compliant module.
An optoelectronic module comprising:
- a housing including a first end wall;
- a circuit board mounted within said housing and an optical subassembly connected to said circuit board;
- a male ribbon style electrical connector at a second end of said housing connected to said circuit board and protruding from said housing for quickly installing and replacing said module to or from a circuit card assembly and the male ribbon style connector having at least a pair of metallic fingers extending from said housing to provide for hot plugging of the module;
- and
- a ground tab providing an electrical connection between the housing of the module and a chassis faceplate of a host device to which the module is mounted.
