System and method for testing optical fibers that lead between a telecommunications provider and a customer's premises

摘要

A system and method for testing the integrity of a pair of optical fibers that are received by a specific customer facility through the optical fiber network of a telecommunications provider. In one embodiment, the system contains a monitor and test access module including a wavelength division multiplexer for each pair of optical fibers that lead to a customer facility and an optical tap and monitoring circuit for monitoring the optical signal transmitted from the customer facility. Monitoring of the optical signal generated from the customer location gives an indication of the general quality of the fiber optic connection. A remote fiber test system that includes an optical time domain reflectometer can be coupled through the monitor and test access module. The optical fibers can be tested one at a time, or the two optical fibers leading to the same customer facility can be looped together and tested at the same time. Alternately, an optical test signal source for producing said optical test signal and an optical signal monitor for detecting the optical test signal can be routed through the monitor and test access module.
