适用范围：This part of IEC 61280 is intended to characterize the encircled flux of two types of lightsources: transmission light sources, which are usually coherent and substantially under-excitethe mode volume of a multimode fibre, and measurement light sources, which are incoherentand excite most of the mode volume of a multimode fibre.This part of IEC 61280 sets forth a standard procedure for the collection of two-dimensionalfibre optic nearfield greyscale data and subsequent reduction to one-dimensional dataexpressed as a set of three sampled parametric functions of radius from the fibre’s opticalcentre. This revision of IEC 61280-1-4 continues to fulfil its original purpose, characterizationof transmission light sources, which enables the accurate mathematical prediction of minimumguaranteed link length in 1 gigabit per second or greater fibre optic data communicationsystems. New to this revision is support for improved measurement precision of insertion lossin multimode fibre optic links through the characterization of measurement light sources.Estimation of the fibre core diameter is not an objective of this standard.
