ABSTRACT:
An optical apparatus having a loss compensation capability includes between an input connector1A and an output connector1B an input side optical parts2including an input monitor, an amplification medium3, a loss medium4, and an output side optical parts5including an output monitor in this order, and is provided with a control circuit6for 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 medium3to the output connector1B, can be smaller than the amount of reflection attenuation on the end face of the output connector1B.
