METHOD AND APPARATUS FOR COLLATING OPTICAL CABLE

PURPOSE:To easily collate even a non-metal cable even at a long distance. CONSTITUTION:Reference light is allowed to be incident from the transmission part 3 provided to one end of the optical fiber 2 of an optical cable 1 and strain such as bending is cyclically applied to the strain generating par...

Zusammenfassung:	PURPOSE:To easily collate even a non-metal cable even at a long distance. CONSTITUTION:Reference light is allowed to be incident from the transmission part 3 provided to one end of the optical fiber 2 of an optical cable 1 and strain such as bending is cyclically applied to the strain generating part 5 on the way of the optical cable 1 from the outer periphery of the cable 1 and the fluctuation of a light detection level corresponding to the polarization fluctuation of reference light is monitored in the receiving part provided to the other end of the optical fiber 2.
