Fibre optics - Multimode launch conditions - Part 1: Launch condition requirements for measuring multimode attenuation
IEC 62614-1:2020 describes the launch condition requirements used for measuring multimode attenuation in passive components and in installed cable plants. In this document, the fibre types that are addressed include category A1-OMx, where x = 2, 3, 4 and 5 (50 µm/125 µm), and A1-OM1 (62,5 µm/125 µm) multimode fibres, as specified in IEC 60793-2-10. The nominal test wavelengths detailed are 850 nm and 1 300 nm. This document can be suitable for multimode attenuation measurements for other multimode categories and/or other wavelengths, but the source 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 are used;- to ensure consistency of factory measurements when different types of test equipment are used;- to ensure consistency of field measurements when compared with factory measurements.This document describes launch condition requirements for optical attenuation using sources with a controlled encircled flux (EF). This first edition cancels and replaces IEC 62614, published in 2010, and constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 62614:a) increase of the value of the uncertainty attenuation variation coefficient Y for 50 µm core fibre at 1 300 nm, due to launch conditions, to twice the previous value;b) changes to 3.4, 5.6, including Table 5, and some references to remain consistent with IEC 61280-4-1:2019;c) changes to multimode fibre references to be consistent with IEC 60793-2-10:2019.

Fibre optics - Launch condition requirements for measuring multimode attenuation
IEC 62614:2010 describes the launch condition requirements used for measuring multimode attenuation in passive components and in installed cable plants. In this standard, the fibre types that are addressed include category A1a (50 m/125 m) and A1b (62,5 m/125 m) multimode fibres, as specified in IEC 60793-2-10. The nominal test wavelengths detailed are 850 nm and 1 300 nm. This standard may be suitable for multimode attenuation measurements for other multimode categories and/or other wavelengths, but the source condition for other categories and wavelengths are not defined here.
