The optical transceiver is composed of optoelectronic devices (TOSA, ROSA, BOSA), functional circuit (PCBA) and optical interface. Its function is to achieve photoelectric conversion. The transmitting end converts electrical signals into optical signals, and the receiving end converts the optical signal into electrical signal through the optical fiber transmission. ETU-Link sincerely recommend you...
