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.
