Removable transceiver module and receptacle

An optoelectronic transceiver receptacle comprising:

• a transceiver receptacle located on a circuit card of a communication system chassis and the communication system having components that generate and use timing signals or pulses at a rate in excess of 9,000 cycles per second, and the receptacle including
• a first end having a protective door mounted thereto, the protective door formed of a conductive material and providing EMI shielding from radiating components on the circuit card in order to provide an FCC compliant communication system;
• and
• a first grounding means including a ground tab extending into the receptacle and mounted at second end of the receptacle;
• an electrical receptacle connector mounted at the second end of the receptacle;
• and
• the receptacle connector having a second grounding means, the receptacle connector for receiving a connector of a removable optoelectronic transceiver module and a majority of the module is received within the receptacle and wherein the module is grounded upon insertion within the receptacle via a ground contact finger offset from a signal contact finger so that the ground contact finger mates with a corresponding ground contact finger prior to the mating of the signal contact finger with a corresponding signal contact finger wherein the first grounding means and the second grounding means provide for the harmless dissipation of static charge and provides for the proper sequencing of power connections to facilitate hot plugging of the optoelectronic transceiver module.

A removable optoelectronic transceiver module comprising:

• a transceiver module housing having a first end and a second end;
• a latching means attached adjacent the first end;
• a pluggable electrical connector at the second end having a shroud, the pluggable connector for mounting the module within a chassis;
• and
• a first ground member located outside of the shroud including a metallic surface adjacent the pluggable connector providing for a first electrical connection to a receptacle;
• a second ground member surrounded by the shroud, isolated from the first ground member, the second ground member adjacent module signal contacts and providing a second electrical connection between the second ground member and a ground contact of the receptacle, both of said first and second electrical connections occurring prior to the electrical connection of at least some of the adjacent module signal contacts wherein the first and second ground members provide for the harmless dissipation of static charge;
• and
• the receptacle including a first end having a conductive door mounted thereto providing EMI shielding from radiative components within the chassis and upon mating of the pluggable connector through the conductive door and within the receptacle a majority of the module is received within the receptacle and the first and second ground members contact the receptacle in order to reduce electromagnetic interference and provide for an FCC compliant module.

A removable transceiver module comprising:

• a housing including a first end;
• a circuit board mounted within said housing and an electronic circuit connected to said circuit board adjacent said first end;
• a plug receptacle at the first end;
• an electrically conductive surface;
• 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 receptacle mounted to a circuit card assembly and the male ribbon style connector including an insulating beam extending from said housing and having metallic fingers on each side of the beam to provide for hot plugging of the module wherein the ground contact is mated before the signal contact when the male ribbon style connector is mated within the receptacle and
• the receptacle including a conductive door providing for EMI shielding of conductive components on the circuit card assembly and when a majority of the module is received within the receptacle the electrically conductive surface is conductivity coupled to a chassis of the circuit card assembly in order to provide a reduction of electromagnetic emissions from the module and to provide an FCC compliant circuit card assembly.
