Apparatus and method employing depolarization to eliminate effect of polarization dependent loss

An apparatus for measuring the IL (insertion loss) and the PDL (polarization dependent loss) of an optical device, includes a first switch adapted to connected to plural light sources on one side and to either a first depolarizer or a polarization controller on the other side thereof. A second switc...
