Primary stage optical switch for an optical fiber administration system

摘要

An optical switch device that includes a primary optical port for receiving a first optical signal from testing equipment such as an optical time domain reflectometer. The optical switch device also includes a plurality of connector ports for connecting to external optical fibers. An optical switching mechanism is used to optically connect the primary optical port to a selected one of the connector ports. At least one secondary optical port is also provided for receiving at least one second optical signal from an alternate piece of testing equipment. A multiplexing element is disposed between the optical switching mechanism and the connector ports. The multiplexing element combines the first test signal and the at least one second test signal to produce a multiplexed signal. The multiplexed signal is propagated through the optical fibers being tested, thereby enabling multiple tests to be performed on the optical fiber at the same time.
