OPTICAL FIBER LINE IDENTIFICATION SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To reduce labor and cost required for identification operation and to maintain transmission loss at a high level by accurately identifying an individual optical fiber core without especially devising.

SOLUTION: A testing device 10 is arranged in a facility building 1, a test beam from the testing device 10 is made incident on an optical fiber line to be identified through an optical coupler 7 and a reflected beam (return test beam) of the test beam by an ONU is received by the testing device 10 through the optical coupler 7. Received waveform data of the return test beam received by the testing device 10 is transferred to an information processing apparatus 14. The information processing apparatus 14 finds out correlation on a time base between the received waveform data and default waveform data previously stored in a waveform database 12, returns a core number corresponding to the default waveform data of which the correlation value is a threshold or less to the testing device 10 and allows a display device 10-10 to display the core number.
