ITU-T L.109 PDF

This Recommendation describe cables containing both optical fibres and metallic wires and covers the following aspects.

– Optical/metallic hybrid cables for communications systems.

– Construction of optical/metallic hybrid cables. The optical fibre dimensional and transmission characteristics, together with their test methods, should comply with [ITUT G.652], [ITU-T G.653], [ITU-T G.654], [ITU-T G.655], [ITU-T G.656], [ITUT G.657] and [IEC 60793-2-10]. Dimensional and transmission characteristics of metallic wires and coaxial units for telecommunication, together with their test methods, should comply with [b-ITU-T TR-OFCS];

– Cables designed for outdoor, indoor or indoor-outdoor use: fibre-to-the-antenna (FTTA) or distributed antenna systems (DAS) cables are examples of such hybrid cables.

– Cables for limited powering applications found in communications systems.

– A recommendation that an optical/metallic hybrid cable should be provided with cable-end sealing and protection during cable delivery and storage, as is usual for metallic or optical cables. If splicing components have been factory installed, they should be adequately protected.

– A recommendation that pulling devices can be fitted to the end of the cable if required.
