  • Optical fiber status analyzer and related methods
    Patent number: 5742715
    Abstract: The apparatus of this invention includes a macrobend/microbend unit which imposes first and second macrobends, and microbends between the first and second macrobends, on an optical fiber under analysis. If light is travelling in one direction on the optical fiber, the bending of the optical fiber is such that some light will escape from the core of the optical fiber at the first macrobend. A first photodetector is arranged to receive light emitted from the first macrobend, and generates a signal indicative of whether light is present at the first macrobend. If light is travelling in the optical fiber in the other direction, the second macrobend causes some light to be emitted. A second photodetector arranged to receive light from the second macrobend, generates a signal indicative of whether light is present at the second macrobend.
