BIDIRECTIONAL COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a bi-directional communication system which is in simple structure, easily made compact, and reduced in cost low by adopting the structure which is different from that of a conventional bidirectional communication system. SOLUTION: Translucent media 30A and 30B are arranged which have light emitting elements 11A and 11B and light receiving elements 13A and 13B at both the ends of a single-core optical fiber 18 and have a light diffusing function. In concrete, the light emitting element 11A and light receiving element 13A are connected to an end surface of the translucent medium 30A and end surfaces of the optical fiber 18 are connected to the mutually opposite end surfaces; and the opposite end surface of the optical fiber 18 is connected to the end surface of the translucent medium 30B and the light emitting element 11B and light receiving element 11A are optically connected to the opposite end surface of the translucent medium 30B. The light receiving element 13A receives the light signal generated by the light emitting element 11B and the light receiving element 13B receives the light signal generated by the light emitting element 11A.
