Abstract
An optical communication system according to the present invention includes an optical transmission device and a repeater. The repeater has an automatic level controller for performing average level constant control to an optical signal transmitted from the optical transmission device. The optical transmission device has an average level detector for detecting an average level detection signal of the optical signal transmitted to the repeater, and the average level detector transmits the average level detection signal to the repeater. When the automatic level controller of the repeater detects an average level detection signal, the automatic level controller performs average level constant control for the optical signal with reference to the average level detection signal.
