Smart SFP OTDR is a Gigabit Ethernet transceiver with built-in OTDR function, IP management and advanced network monitoring and troubleshooting features.

Acting like a conventional SFP transceiver, once detecting optical fiber fault it automatically measures the distance to the fault point and reports it. Due to support of open REST API and traditional SNMP, it can be easily integrated into any monitoring system – NMS, OSS, NIMS, GIS or even SDN.

Smart SFP OTDR is installed in any network equipment vendor for fast break point identification of the optical fiber and for real time L1 optical links monitoring in the mobile backhaul and ISP’s last mile.

Due to IP management Smart SFP OTDR doesn’t require additional integration with network equipment.



  • Instant fiber break point identification
  • Real time remote fiber monitoring
  • Operating over dark fiber and CWDM
  • Reduce MTTR by locating fiber optic faults in seconds
  • Reduce OpEx by eliminating multiple false technician dispatches
  • Eliminate the need for separate low level fiber element monitoring system by integrating in high level management system (OSS, NMS)
  • Cheaper than standalone or rack-mounted OTDR unit
  • No free rack space required
