ABSTRACT:
The optical transceiver of the present invention is one type of the pluggable transceiver that is inserted into/extracted from the cage in the host system. The transceiver includes the OSA (Optical Sub-Assembly) unit, which shows the optical function, and the body unit installing the electronic circuit. The OSA unit includes the receptacle member, the tab plate and transmitting/receiving sub-assemblies. The body unit includes the base installing the circuit board, the heat conducting plate to conduct heat generated by the IC on the substrate to the rear end of the transceiver, the supplementary substrate, the supporting plate, and the cover for putting these components therein. In the present transceiver, the heat is effectively conducted to the rear end thereof the heat conducting plate, besides, the tab plate, the heat conducting plate, and the supporting plate are made only by cutting, bending and tapping without any welding and gluing. Therefore, the present invention may provide an optical pluggable transceiver with superior heat dissipating function by cost saved configuration.
