FiberSentinel’s primary monitoring function is to identify and characterise; intrusions, intruder-based light  injections, cable breaks, cable degradation and transients. In the event of any one of these situations being detected, FiberSentinel will divert the data signal to a backup pathway without any loss of data.

The FiberSentinel System (FSS) can be installed on any point-to-point, singlemode fibre optic communications network. FSS is fully protocol independent and therefore provides continuous, real-time monitoring capabilities regardless of network protocol or data rate. The FiberSentinel System is installed in pairs with one FSS unit attached in-line at each end of the duplex fibre path.

FiberSentinel is designed to monitor a duplex fibre path, whereby local communications equipment has both a transmit path and a receive path. Since FiberSentinel has the capability to take automatic, proactive protective measures in the case of an intrusion or cable break, a backup duplex fibre is required between the two ends of the point-to-point network. In order to reduce the likelihood of a double cable break, the backup path should be routed over a physically separate network path.
