摘要： PROBLEM TO BE SOLVED: To provide an optical amplifier which has a stable gain characteristic with respect to the power of inputted signal light. SOLUTION: Power of amplified low interference light is detected, and at the same time, the power of a low interference light source 13 is controlled, so that the power of the low interference light is fixed by inputting a wide band of low interference light from the light source 13 to a rare-earth doped optical fiber 1 from the rear side, without the use of the gain stabilization by laser oscillation. Therefore, gain fluctuation caused by the hole burning effect, which is seen when the gain of an optical amplifier is stabilized by the conventional laser oscillation, is eliminated, and the gain of the optical amplifier can be kept constant over a wide power range of input signal light.

SOLUTION: In the optical transmission system to synthesize and receive the optical signals from plural terminal stations, each optical signal is inputted in each input port of an optical star coupler with plural input ports and plural output ports, synthesized optical signals outputted from each output port are received by light receiving elements 2 respectively, after that these received signals are added together. Since a phase difference is generated in beat noise component of each synthesized optical signal, beat noises are mutually muted by addition.
