IEC/TR 62349 (2014-02)

IEC TR 62349:2014(E) applies to polarization-maintaining (PM) optical fibres. The object of this report is to define test procedures to be used in establishing uniform requirements for the geometrical and transmission properties of PM fibres. This second edition cancels and replaces the first edition published in 2005. It constitutes a technical revision. In this edition, guidance of measurement methods and test procedures for dimensional characteristics, cut-off wavelength, mode field diameter and beat length of polarization-maintaining optical fibres have been added. Thus, the title of the technical report is changed to 'Guidance of measurement methods and test procedures - Basic tests for polarization-maintaining optical fibres' from 'Guidance for polarization crosstalk measurement of optical fibre'. Keywords: polarization-maintaining (PM) optical fibres, geometrical and transmission properties
