Description

IEC 60793-1-61 Ed. 1.0 b – Optical fibres – Part 1-61: Measurement methods and test procedures – Polarization crosstalk

IEC 60793-1-61: 2017 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 Clause 6. Crosstalk values obtained by Methods A and B are based on different definitions.
