Optical fibres - Part 1-44: Measurement methods and test procedures - Cut-off wavelength
Provides methods for measuring the cut-off wavelength of single-mode optical fibres. 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.
