OPTICAL NETWORK MONITORING SYSTEM

摘要

A system (10) for monitoring and managing optical networks (102). The system (10) includes tapping a test signal from optical signals in the optical network (102), routing the test signals through a Nx1 switch (108), to a 1xN switch (202), and to a selected test device (204). A processor (112) controls the switching (302, 304, 306, 308, 310) and monitors the test results (312), and initiates corrective action (316) as required (314). The corrective action (316) includes grooming and rerouting signals in the optical network (102) in response to a failure or risk of failure.
