Self-automatic gain control distributed Raman amplifier and automatic gain control method

摘要

Disclosed is a self-automatic gain control distributed Raman fiber amplifier, in which a signal is transmitted to a self-AGC monitor and a PD via a pump/signal combiner through a transmission fiber and passes through an RFA control circuit, a self-AGC firmware, and an ASCII communication unit and an Raman pump laser module communicates with the RFA control circuit and transmits the signal to the pump/signal combiner.
