Optical communication device

Abstract

An optical communication deviceis provided with: a plurality of light-receiving elementseach configured to receive light and output a light detection signal; a plurality of optical fibersprovided to correspond to the plurality of light-receiving elements, respectively, the plurality of optical fibers each being configured to guide the light to the corresponding light-receiving element; a plurality of amplifiersprovided to correspond to the plurality of light-receiving elements, respectively, the plurality of amplifiers each being configured to generate optical communication information by performing signal processing on the light detection signal; a light intensity information collection unitconfigured to collect intensity of the light received by each of the plurality of optical fibersas light intensity information; an optical fiber identification unitconfigured to identify the optical fiberthat is receiving relatively strong light out of the plurality of optical fibers, based on the light intensity information La to Le collected by the light intensity information collection unit; and a switch controllerconfigured to control to turn on the amplifier, the amplifierbeing provided to correspond to the optical fiberidentified by the optical fiber identification unit
