Controlling expenses related to operation, support and maintenance of FTTH networks is key for operators to ensure a fast return on their capital investments. Nowadays, for FTTH deployments, vendors offer platform-agnostic (equipment-vendor independent) in-service OTDR testing and monitoring from the central office. To capture, locate and report fiber impairments from the central office, three solutions are available on the market.
This presentation will show and discuss the various available solutions and their respective pros and cons. Finally, a new methodology will be presented to certify new PON installations from the central office using a 1310 nm OTDR, a 1490 nm OTDR and a broadband reflector.
