The object of this part of IEC 61300 is to determine the dependence of attenuation in single-mode fibre optic devices to changes in polarization. This procedure can be applied to any single-mode interconnecting device and passive component, including connectors, splices, branching devices, attenuators, isolators and switches. It is used to measure the total range of attenuation, △a, due to changes in polarization of the launch state. For branching devices, it can also be used to measure the total range of coupling ratio, △CR(i). It cannot be used to measure the polarization dependence of return loss.
