Today's core and access networks require new strategies for effective test and monitoring to ensure continued high quality of service and rapid repair
in the event of a failure. It is now cost-effective to implement a centralized remote testing strategy, with simultaneous testing of high fiber count cables.
If the switch is used in-line with traffic, it is possible to simultaneously monitor all channels and submit alarms in the event of partial or complete signal
drop. Maintenance can be planned based on fault prediction, and failures can be minimized. Low insertion loss maximizes the dynamic range of the test
instrument, the organization can monitor dark or active fiber and the non-blocking matrix allows high fiber counts and simultaneous tests.
