Optical transceiver with a pluggable function

An optical transceiver configured to be inserted into or extracted from a cage provided in a host system, the cage exposing one end thereof from a face panel of the host system and providing an electrical connector in the other end thereof, the transceiver comprising:

• an optical assembly unit including,
• a receptacle member, made of resin, configured with an optical receptacle for receiving an optical connector,
• a tab plate made of metal and engaged with the receptacle member, and
• an optical subassembly including a semiconductor optical device optically coupled with an optical fiber configured with the optical connector, the optical subassembly being installed on the receptacle member;
• and
• a body unit including,
• a substrate mounting an electronic circuit and mating with the electronic connector provided within the cage,
• a metal base installing the substrate and engaged with the optical assembly unit,
• a heat conducting plate made of metal and being in contact to the electronic circuit mounted on the substrate, the heat conducting plate being engaged with the metal base, and
• a metal cover putting the substrate, the optical subassembly, the metal base, and the heat conducting plate therein,
• wherein the tab plate, the base, the heat conducting plate, and the cover are made from a metal plate by cutting, bending, and tapping without welding and gluing.
