Abstract
A method and system for measuring signal loss in a fiber optic cable. The tail ends of reference and test fiber optic cables are illuminated with a diffuse light. The head end of each of the reference and test fiber optic cables are positioned in a measurement area. A core imager captures an image of the core of each head-end while it is in the measurement area. Reference and test radiant fluxes emitted from the reference and test head-ends are determined from the respective core images. The relative signal loss of the test fiber optic cable is then determined by comparing the test radiant flux to the reference radiant flux.
