Optical Switch + OTDR Monitoring Case Study

The optical path selector + OTDR monitoring solution effectively addresses the issue of OTDR utilization efficiency during multi-cable monitoring.

The control unit initiates and switches to the fiber under test to perform an OTDR fiber performance roll call test. Alternatively, through timed polling, the control unit can direct the OTDR and optical switch to conduct periodic testing. Analysis of the OTDR curve identifies the alarm type and pinpoints the alarm location.
