IEC 61280-1-4:2023 is available as IEC 61280-1-4:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61280-1-4:2023 establishes the characterization process of the encircled flux measurement method of light sources intended to be used with multimode fibre. This document sets forth a procedure for the collection of two-dimensional fibre optic nearfield greyscale 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. Estimation of the fibre core diameter is not an objective of this document. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:全文を表示する
- improvement of calibration procedure and calibration traceability;
- improvement of fibre shaker description and requirements;
- addition of pulsed light sources;
- removal of a poorly traceable calibration process using a micro positioner.
