UNINTERRUPTIBLE OPTICAL COMMUNICATION EQUIPMENT AND UNINTERRUPTIBLE OPTICAL COMMUNICATION METHOD

PROBLEM TO BE SOLVED: To provide the uninterruptible optical communication equipment in which a leaked light is received stably without being affected by a sheath of an optical fiber, long distance communication is available and a danger such as a damaged or broken optical fiber is less. SOLUTION: A grip section 3 and a fixed plate 4 are provided in the vicinity of a connection reinforcement section 2 of an optical fiber 1 to provide a bent to the optical fiber and an optical sensor 5 is fitted to the grip section 3 to receive a modulation light leaked from the connection reinforcement section 2 and the equipment is used at a connection work point. The grip section 3 is fitted slidably vertically and the connection reinforcement section 2 of the optical fiber 1 is fitted to an insertion groove 3a. An outgoing optical fiber 1c is in existence to the left of the connection reinforcement section 2. The right side optical fiber has an optical fiber bent 1b and it is extracted from a main body 6 while being inserted between a vibration plate 7 and the fixed plate 4.
