Manufacturers of fi ber optic components like multiplexers, attenuators, and amplifi ers must characterize their products for parameters such as insertion loss and polarization-dependent loss. Insertion loss is usually accomplished by measuring output power variations before and after the component has been connected to a laser source. Polarization-dependent loss is measured by varying the input polarization to the device and measuring the variation in power as the polarization vector is swept through all possible angles.
