Abstract
An optical apparatus having a loss compensation capability includes between an input connector 1A and an output connector 1B an input side optical parts 2 including an input monitor, an amplification medium 3, a loss medium 4, and an output side optical parts 5 including an output monitor in this order, and is provided with a control circuit 6 for controlling a gain based on a monitor result of input/output light. The amount of reflection attenuation on all points, on which the light can be reflected on the optical path from the output end of the amplification medium 3 to the output connector 1B, can be smaller than the amount of reflection attenuation on the end face of the output connector 1B.
