Abstract
Aiming at the problem that the optical cable is wrongly disconnected due to false identification in the maintenance of the power optical cable, we propose a scheme of multi-channel optical cables identification based on phase sensitive optical time-domain reflection technology. Electric optical cables identification system based φ-OTDR is experimentally demonstrated, with a monitoring channel number of 4 and SNR over 15dB.
