IEC 60793-1-44 Ed. 2.0 en:2011

IEC 60793-1-44:2011(E) establishes uniform requirements for measuring the cut-off wavelength of single-mode optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. The test method applies to a sample fibre in either an uncabled condition, or in a cable, or as a jumper cable. All methods require a reference measurement, with either a bend-reference technique or a multimode-reference technique. The main change with respect to the previous edition is the withdrawal of annex D.

This publication is to be read in conjunction with IEC 60793-1-1:2008.
