Abstract
In an optical monitor for monitoring signal lights from a plurality of optical fibers, emission surfaces of the plurality of optical fibers are arranged along a straight line, and a photodetecting surface of a photodetecting element disposed so as to face the emission surfaces is moved in parallel to the straight line along which the emission surfaces are arranged in such manner that light from each of the emission surfaces is received by the photodetecting element, so that the plurality of signal lights are made incident on the photodetecting element successively. The present optical monitor thereby is capable of monitoring a large number of transmission paths while requiring a small number of components.
