IEC 60794-5-10:2014 is a family specification that covers outdoor microduct optical fibre cables for installation by blowing and the associated microducts, which together make up a microduct optical fibre cable system. Although primarily designed for use with outdoor microduct applications, the cable products specified herein may be used individually for short lengths in other applications as agreed upon between supplier and customer. These may include short runs inside a building or in other outdoor applications, such as a transition between separate (unconnected) microduct systems, or from a microduct system to some other protective structure such as a cable conduit or tray. Systems built with components covered by this standard are subject to the requirements of IEC 60794-5 where applicable. Keywords: outdoor microduct optical fibre cables, installation by blowing
