ABSTRACT:
An instrument and method is provided for verifying the routing of and measuring the insertion losses of multiple fiber optic assemblies. Each light source launches the same amount of light power into each fiber. Correcting factors are provided for the responsivity of each detector. Optical switches are avoided. Calibration of base optical powers is reduced and made independent of the cable assembly. Base optical power is equalized for all fibers. A responsive correction is also provided for all detectors. The number of times that the connectors are mated and unmated is also reduced.
