Patent ID: 7113267

Claim:
An instrument for verifying routing and measuring optical insertion losses in multiple connectors, multiple fiber cable assemblies comprising: multiple light sources for launching light having a level of optical power through each fiber assembly at a first end of the fiber assembly; multiple light detectors operably connected to and corresponding to the light sources at the opposite end of the fiber assembly for reading the optical power of the light passing through the fiber assembly; the light sources being operatively associated with a power source so that each light source can be made to launch the same amount of optical power into each fiber assembly; a processor operatively connected to said light sources and said light detectors for selectively activating a light source and its corresponding detector to determine the amount of optical power passing through the fiber assembly; said corresponding detector further being capable of indicating that no light has passed through the assembly and to that corresponding detector and thereby indicating a misrouted or broken fiber; and, said processor further being capable of selectively activating a light source and checking every detector for light erroneously launched to a detector other than the corresponding detector for that light source, so as to indicate a misrouted fiber.
