DIN EN 61280-1-4 VDE 0885-801-4:2010-09
Fibre optic communication subsystem test procedures - Part 1-4: General communication subsystems - Light source encircled flux measurement method (IEC 61280-1-4:2009); German version EN 61280-1-4:2010More info
This standard is intended to characterize the encircled flux of two types of light sources: transmission light sources, which are usually coherent and substantially under-excite the mode volume of a multimode fibre, and measurement light sources, which are incoherent and must 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-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 centre.
