NTest

A Remote Fiber Test System (RFTS) utilizing optical time-domain-reflectometer (OTDR) technology is a well-known tool for monitoring and troubleshooting optical fibers in cabled optical networks. The fault data can then be correlated with the Geographical Information System (GIS) to isolate the fault and pin point the problem location on a map. Once a network is in operation, a carrier can permanen

tly place a remote OTDR in a rack mount configuration at a centralized location, which can be programmed to routinely test critical fibers to quickly locate fiber failures, detect network intrusions as well as predict fibers that are degrading and likely to fail.
