Optical fibres - Measurement methods and test procedures. Polarization crosstalk Ingestion-build-86103 edge losses become appreciable)What is BS EN 60793 1 61 Polarization crosstalk of PM fibres about? BS EN 60793 1 61 is a part of the BS EN 60793 multi series that discusses optical fibres. BS EN 60793 1 61 establishes uniform requirements for measuring the polarization crosstalk of polarization maintaining (PM) fibres. BS EN 60793 1 61 gives two methods for measuring the polarization crosstalk of PM fibres. Method A is the power ratio method, which uses the maximum and minimum
