Guidance for residual stress measurement of optical fibreWhat is PD IEC TR 62469 Residual stress measurement of optical fibre about? The measurement of residual stress distribution in an uncoated glass optical fibre is important as it affects critical fibre parameters such as refractive index, intrinsic polarization mode dispersion, mode field diameter and dispersion. PD IEC TR 62469 is a technical report that describes a transverse polarimetric method to measure the residual stress profile of any type of
