Abstract:
A method for measuring a loss through optical fibers, the method comprising the steps of:providing a first fiber optic cable having a plurality of optical fibers with first and second ends; coupling the plurality of optical fibers at the first ends to an output end of an optical switch; coupling the plurality of optical fibers at the second ends to a first fiber holder; attaching the first fiber holder to an adapter; coupling the adapter to an input end of an integrating sphere to optically couple each of the plurality of optical fibers to the integrating sphere; coupling an input end of the optical switch to a light source, the light source capable of delivering light of a known quantity to the optical switch; transmitting light through each of the plurality of optical fibers from the first ends to the integrating sphere including activating the optical switch such that the light is transmitted through each of the plurality of optical fibers; and measuring a quantity of light received at the integrating sphere passing through at least one of the plurality of optical fibers.
