Patent ID: 7079743

Claim:
An apparatus for estimating an optical insertion loss of a fiber optic jumper cables comprising: an imaging assembly, the imaging assembly comprising: a mating portion, wherein the mating portion is used for positioning a first ferrule of the fiber optic jumper cable and includes a longitudinal bore therethrough so that the mating portion does not physically contact the optical connection portion of a first ferrule end face of the fiber optic jumper cable during testing, wherein the longitudinal bore of the mating portion has a diameter of about 1 millimeter, thereby allowing imaging of the optical connection portion; a lens, the lens for magnifying the image of the optical connection portion of the first ferrule end face of the fiber optic jumper cable; and a camera, the camera being used for imaging the optical connection portion of the first ferrule end face and outputting a signal; a frame grabber, the frame grabber being used for digitizing the signal from the camera; a computing device, the computing device receives the signal from the frame grabber and calculates an estimate of the optical insertion loss for the fiber optic jumper cable.
