Telecoms Carriers and Service Providers use Managed Ethernet Demarcation Devices (EDDs) to provide full end-to-end visibility and control of their Layer-2 infrastructure.
Advanced EDDs incorporate test-traffic generation and protocols such as ITU-T Y.1731 to monitor key service-level characteristics such as Frame Loss, Latency and Jitter.
Now, it is possible to incorporate fibre integrity checking and fault-reporting to such devices. Specifically, Optical Time Domain Reflectometer (OTDR) functionality, integrated directly into EDD fibre interfaces, provides a cost-effective solution to Carriers for fibre fault determination and localisation, reducing costs and time-to-repair for customer services.
