TESTING OPTICAL FIBER LINK CONTINUITY USING OTDR BACKSCATTERING PATTERNS

Abstract:

There are provided methods and systems for testing the continuity of optical fiber links under test and/or a fiber arrangement, polarity or mapping of optical fiber connections within optical devices under test using the backscattering pattern as a signature. The device under test may comprises a single fiber, a duplex link, a multifiber cable or another multi-port device such as a backplane device.
