This part of IEC 60793 establishes uniform requirements for measuring the polarization crosstalk of polarization-maintaining (PM) fibres.This report gives two methods for measuring the polarization crosstalk of PM fibres. Method A is the power ratio method, which uses the maximum and minimum values of output power at a specified wavelength, and Method B is the in-line method, which uses an analysis of the Poincaré sphere.Details of each method are described in Clause 6.Crosstalk values obtained by Methods A and B are based on different definitions.The crosstalk measured by Method A is defined as an 'averaged' value over a measured wavelength range. In contrast, the crosstalk value obtained from Method B shows 'the worst case' crosstalk value.
