What is BS EN 50411-2-9 - Fibre organisers and closures to be used in optical fibre communications systems about?

BS EN 50411 is a series on fibre organisers and closures to be used in optical fibre communications systems. Fibre organisers and closures are devices used to provide space and protection for fibre optic cables spliced together. BS EN 50411-2-9 contains the initial, start of life dimensional, mechanical, and environmental performance requirements that a fully installed blown fibre protected, non-sealed closure for duct and micro duct cable, must meet in order for it to be categorised as an EN standard product. These products are suitable for installation of and use with micro-duct fibre units, micro duct optical fibre cables, micro duct and protected micro dust as defined within EN 60794-5 . When the non-sealed closures are installed in subterranean environments it is mandatory to use sealed ABF connectors meeting EN 50411-2-8 in order to guarantee the expected network performance and reliability.
