Fibre optics - Multimode launch conditions - Part 1: Launch condition requirements for measuring multimode attenuation
- 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.
