IEC 61300-3-55 provides methods for measuring the polarisation extinction ratio (PER)of single-mode, polarisation maintaining (PM) optical components based upon PM fibres. Thisdocument also provides methods for detecting the input and output orientation of the PMcomponents' principal axes as well as methods for estimating the keying accuracy, i.e. theangular misalignment between the principal axes and the mechanical reference guide key ofthe connectors, if these are present.
