This Recommendation:
– refers to multimode graded index and single-mode optical fibre cables to be used for
telecommunication networks within buildings;
– deals with 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 ITU-T Recs G.652, G.653, G.654, G.655, G.656
and G.657 which describe single-mode optical fibres and ITU-T Rec. G.651.1 and and IEC
60793-2-10, which describe multimode graded index optical fibres;
– deals with fundamental considerations related to optical fibre cable from mechanical and
environmental aspects;
– acknowledges that some optical fibre cables may contain metallic elements, for which
reference should be made to the handbook, Outside plant technologies for public networks
(see ITU-T Rec. L.1), and other L-series Recommendations;
– recommends that an optical fibre cable should be provided with cable end-sealing and
protection during cable delivery and storage, as is common for metallic cables. If splicing
components have been factory installed, they should be adequately protected;
– recommends that pulling devices may be fitted to the end of the cable if required.
