The OTDR functionality underpinning this capability is based on the principle of measuring the time delay between transmission of a pulse of light from the optical transceiver and reception back at the transceiver of a corresponding pulse 'reflected' back from the discontinuity (i.e. the breakage or disconnection point). This is represented graphically in the diagram below.
Metrodata Ltd. is the strong first EDD vendor to incorporate full commercial support for automated OTDR-based fault detection in this manner, and is pleased to be working in co-operation with Optical Zonu Corp. to bring not only comprehensive Ethernet service monitoring in terms of throughput, packet-loss, latency and jitter, but now also physical layer fibre fault detection and localisation, to its Telecoms Carrier and Ethernet Service Provider customers.
