This Recommendation:

– Applies to multimode and single-mode optical fibre cables to be used for telecommunication networks within buildings;

– Specifies the mechanical and environmental characteristics of the optical fibre cables concerned. The optical fibre dimensional and transmission characteristics, together with their test methods, should comply with one or more of [ITU-T G.651.1], [ITU-T G.652], [ITU-T G.653], [ITU-T G.654], [ITU-T G.655], [ITU-T G.656], [ITU-T G.657] and [IEC 60793-2-10];

– Specifies the fundamental considerations related to optical fibre cable from mechanical and environmental aspects;

NOTE – Other types of fibre may be used to meet the intent of cables according to this Recommendation. Specific attributes may differ, and require agreement between the manufacturer and user.
