适用范围：This International Standard describes the launch condition requirements used for measuringmultimode attenuation in passive components and in installed cable plants.In this standard, the fibre types that are addressed include category A1a (50 μm /125 μm) andA1b (62,5 μm /125 μm) multimode fibres, as specified in IEC 60793-2-10. The nominal testwavelengths detailed are 850 nm and 1 300 nm. This standard may be suitable for multimodeattenuation measurements for other multimode categories and/or other wavelengths, but thesource condition for other categories and wavelengths are not defined here.The purpose of these requirements is as follows:? to ensure consistency of field measurements when different types of test equipment areused;? to ensure consistency of factory measurements when different types of test equipment areused;? to ensure consistency of field measurements when compared with factory measurements.This standard describes launch condition requirements for optical attenuation using sourceswith a controlled encircled flux (EF).
