Optical Transceiver Module

Optical Transceiver Module is mainly composed of electronic device including transmitter and receiver, function circuit and optical interface. The function of the optical module is photoelectric conversion in which the transmit end converts electrical signals into light signals while the receive end converts light signals into electrical signals. It is widely used in optical communication network, such as metropolitan-area networks (MAN) and local area network (LAN). Optical module is mainly divided into: GBIC, SFP, SFP+, XFP, SFF, CFP and the commonly used is the SFP, SFP+, XFP which is smaller and cheaper than GBIC.
