Defines uniform requirements for measuring the polarization crosstalk of polarization-maintaining (PM) fibres.

This part of IEC60793 establishes uniform requirements for measuring the polarization crosstalk of polarization-maintaining (PM) fibres. This document 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 Clause6. 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.
