(Definition of Optical Transceiver Integrated Module The optical transceiver integrated module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving. The transmitting part is: the electrical signal inputting a certain code rate is managed by the internal driver chip to drive the semiconductor laser (LD) or light emitting diode (LED) to emit a modulated optical signal of the corresponding rate)
