Optical transceiver module

Disclosed is an optical transceiver module which is unpluggable from electronic devices and is able to provide signal transmission through electrical connection formed by electrical joint of electronic devices. The optical transceiver module mainly comprises a base, a light-emitting unit which provides light signals, light-receiving unit which receives light signals, and a master circuit board. The base is to hold the light-emitting unit, the light-receiving unit, and the master circuit board. The master circuit board has an unpluggable electrical connector which is to be inserted into and electrically connected to the electrical joint, and therefore to coordinate with the optical transceiver module for being assembled in a simplified or optimized of design.
