Optical fibres -- Measurement methods and test procedures. Polarization crosstalk

PUBLISH DATE 2017

PAGES 16

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.
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.

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.
