Fibre optic communication subsystem test procedures - Part 4-1: Cable plant and links - Multimode fibre-optic cable plant attenuation measurement (IEC 61280-4-1:2003); German version EN 61280-4-1:2004
This part of IEC 61280 establishes preferred measurement principles and practices to assure that meaningful data descripbing the optical loss performance of installed cable plants can be obtained. It is not intended for component testing, nor does it define those elements of an installation that need to be measured.#,,#
