1. An optical communication device comprising:
a plurality of light-receiving elements each configured to output a light detection signal by receiving light;
a plurality of optical fibers provided 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 signal processing units provided to correspond to the plurality of light-receiving elements, respectively, the plurality of signal processing units each being configured to provide first communication information by performing signal processing on the corresponding light detection signal output by a corresponding one of the plurality of light-receiving elements;
a light intensity information collection unit configured to collect information of the intensity of the light incident on each of the plurality of optical fibers as light intensity information;
an optical fiber identification unit configured to identify the optical fiber on which relatively strong light is incident out of the plurality of optical fibers, based on the light intensity information collected by the light intensity information collection unit;
a switch controller configured to select a first signal processing unit out of the plurality of signal processing units, the first signal processing unit corresponding to the optical fiber identified by the optical fiber identification unit; and
a position calculation unit configured to calculate position information on a generation source of the light incident on the optical fiber, based on the light intensity information acquired for each of the plurality of optical fibers.
