200G 400G 800G Transceiver
Simply put, the function of the optical module is photoelectric conversion. The transmitting end converts the electrical signal into an optical signal. After transmitting through the optical fiber, the receiving end converts the optical signal into an electrical signal. Data is transmitted stably and at high speed through optical fiber.
The optical module consists of optoelectronic devices, functional circuits and optical interfaces; The optoelectronic device includes two parts: the transmitting part: inputting an electrical signal with a certain bit rate, and after being processed by the internal driver chip, driving the semiconductor laser (LD) or light-emitting diode (LED) to emit a modulated optical signal of the corresponding rate. It has an automatic optical power control circuit inside to keep the output optical signal power stable. The receiving part is: the optical signal with a certain bit rate is input into the module and converted into an electrical signal by the optical detection diode. After passing through the preamplifier, the electrical signal of the corresponding bit rate is output.
