Fibre optic communication subsystem basic test procedures - Test procedures for general communication subsystems. Transmitter output optical power measurement for single-mode optical fibre cable Ingestion-build-100998 This sleeving is suitable for1 Scope and object This part of IEC 61280 applies to fibre optic general communication subsystems. The object of this part is to measure the optical power coupled from the output of a transmitter under test into single mode optical fibre cable containing dispersion unshifted fibre or dispersion shifted fibre.
