Abstract
This optical communication device (1) is provided with a plurality of light-receiving elements (11) and a plurality of optical fibers (12). The plurality of optical fibers each includes a light-incident end portion (12a) for communication light and a light-emission end portion (12b) for communication light. The plurality of light-emission end portions is each arranged near each of the plurality of light-receiving elements. The plurality of light-incident end portions is each configured to be capable of being arranged in a predetermined position in a predetermined direction.
Claims14
An optical communication device comprising:
- a plurality of light-receiving elements configured to receive communication light, the plurality of light-receiving elements being provided so as to correspond to a plurality of channels;
- and
- a plurality of optical fibers having a one to one correspondence for each of the light-receiving elements, configured to guide the communication light to the plurality of light-receiving elements, each of the plurality of optical fibers being provided so as to guide communication light to a corresponding one of the plurality of light-receiving elements,
- wherein each optical fiber of the plurality of optical fibers includes a light-incident end portion for the communication light and a light-emission end portion for the communication light,
- wherein each light-emission end portion of the plurality of light-emission end portions is arranged so as to face a light-receiving surface of a corresponding light-receiving element of the plurality of light-receiving elements,
- wherein the plurality of the light-incident end portions is each configured to be capable of being arranged at a predetermined position in a predetermined direction, and
- wherein the light-incident end portions is configured such that the communication light from a moving body that moves in water is incident on the light-incident end portion.
An optical communication device comprising:
- a plurality of optical fibers, each optical fiber of the plurality of optical fibers dedicated to a corresponding channel of a plurality of channels and having a light-incident end and a light-emission end;
- and
- a plurality of light-receiving elements, each light-receiving element of the plurality of light-receiving elements having a photoelectric converter and dedicated to a respective corresponding channel of the plurality of channels and arranged to receive a communication light transmitted from the light-emission end of an optical fiber dedicated to the channel, and
- wherein each light incident end of the plurality of optical fibers is arranged at a predetermined position independent from one another and at a predetermined direction independent from one another to receive the communication light from a body moving in water,
- wherein each light-emission end of the plurality of optical fibers is arranged to face a light receiving surface of a corresponding light-receiving element of the plurality of light-receiving elements to transmit the communication light thereto, and
- wherein the plurality of optical fibers is configured such that a communication light from a moving body that moves in water is incident on at least one of the light-incident ends.
