Working principle
An optical transceiver is a photoelectric conversion device. It consists of two parts: the sending end and the receiving end. The sending end converts electrical signals into optical signals and transmits them through optical fibers, and the receiving end converts optical signals into electrical signals through photoelectric conversion.
