Network Monitoring

280
The introduction of all-optical switching to C-RAN architectures enables the sharing of centralised monitoring and test equipment across multiple optical fiber fronthaul links interconnecting RRHs and BBUs.

All-optical switch
The Polatis all-optical switch is an out-of-line network element that enables fiber monitoring via passive optical taps. It can switch fibers between test and monitor equipment remotely, in milliseconds, independent of protocol, data rate or colour , in real time to diagnose existing or potential network issues without interfering with user traffic. With all-optical switching, any optical connection can be remotely monitored and tested and can be configured to switch automatically based on reduction, or loss, of the optical signal.
