When deployed in parallel within a network conduit or embedded in a carrier, the Fiber SenSys SL504™/SL508™ Alarm Processor Unit (APU) is the core component used to alarm the network conduit or the raceway.  The SL504/SL508 is a 1U, rack-mounted alarm processor with a single-strand zone design (loop-back is NOT required). The SL504 is a four-zone unit, and the SL508 can support up to 8 zones with remote zone capability - the electronics can be located a significant distance away from the protection zone.

This system can be used to alarm any network segment or raceway, including the alarming of existing "dark" fiber (within distances and specifications), and it is compatible with all varieties of network architectures, including secure passive optical networks (Secure PON).
