IEC 61280-1-4 Ed. 1.0 en:2003, Fibre optic communication subsystem test procedures - Part 1-4: General communication subsystems - Collection and ... data for multimode fibre laser transmitters

Provides a procedure for the collection of two-dimensional fibre optic nearfield grayscale data and subsequent reduction to one-dimensional data expressed as a set of three sampled parametric functions of radius from the fibre's optical center. The object is to reduce measurement errors and inter-laboratory variation.
