scope:

This Recommendation contains definitions and test methods suitable mainly for factory measurements of the linear, deterministic attributes of the single-mode optical fibres and cables described in [ITU-T G.652], [ITU-T G.653], [ITU-T G.654], [ITU-T G.655], [ITU-T G.656] and [ITU-T G.657]. These definitions and test methods are generally not appropriate for multimode fibre, such as specified in [ITU-T G.651.1]. Some of the test methods, when so indicated, may also be used to characterize discrete optical components, such as those described in [ITU-T G.671]. [ITU-T G.650.2] contains definitions and test methods for statistical and non-linear attributes.
