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.

The relative signal loss of the test fiber optic cable is then determined by comparing the test radiant flux to the reference radiant flux.
