ITU-T L.79-2008 PDF

Scope: This Recommendation: - refers to microduct fibre units and microduct cables to be used for telecommunications networks with blowing installation techniques; - deals with mechanical and environmental characteristics of microduct fibre units and microduct cables. The optical fibre dimensional and transmission characteristics, together with their test methods, should comply with IEC 60793-2-10, ITU-T G.652, G653, G654, G.655 G.656 and G.657 which deal with a multi-mode graded index optical fibre and single-mode optical fibres respectively; - deals with fundamental considerations related to optical fibre cable from mechanical and environmental standpoints; - acknowledges that some optical fibre cables may contain metallic elements, for which reference should be made to the manual, Outside plant technologies for public networks (see Recommendation L.1), and other L-Series Recommendations; - recommends that microduct fibre units and microduct cables should be provided with end-sealing and protection during delivery and storage, as used for metallic cables.
