Optical fibres - Measurement methods and test procedures. Polarization crosstalk Ingestion-build-224916 5 Examination1 Scope This part of IEC 60793 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 Poincar sphere.
