What is BS EN 50411-2-3 - Fibre organisers and closures to be used in optical fibre communication systems about?
BS EN 50411 is a series on fibre organisers and closures to be used in optical fibre communication systems. Fibre organisers and closures also known as fibre optic splicing closures is a device used to provide space and protection for fibre optic cables spliced together. BS EN 50411-2-3 contains the initial, start of life dimensional, optical, mechanical, and environmental performance requirements of a fully installed splice closure in order for it to be categorised as an EN standard product.
BS EN 50411-2-3 allows both single-mode and multimode fibre to be used and covers all EN standard optical fibre cables with their various fibre capacities, types, and designs. This includes, but is not limited to, optical fibre cable standards EN 60794-2 (indoor), EN 60794-3 (outdoor).
Who is BS EN 50411-2-3 - Fibre organisers and closures to be used in optical fibre communication systems for?
BS EN 50411-2-3 on fibre organisers and closures is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 50411-2-3 - Fibre organisers and closures to be used in optical fibre communication systems?
The fibre optic closure connects and stores optical fibres safely either in the outside plant or indoor buildings. BS EN 50411-2-3 describes the performance tests that are carried out on test samples with dispersion un-shifted single-mode fibre, the closure, once tested according to BS EN 50411-2-3, will be also suited for other fibre types like dispersion-shifted, non-zero dispersion-shifted and multimode fibres.
An inline fibre splice closures comprises a closure housing that is attached to the ends of the joined cable sheaths and a means for containing and protecting the fibres, fibre splices and other passive optical devices. The closures covered in BS EN 50411-2-3 are those that are split at the cable entry ports. This allows for assembly over pre-installed cables or where there is no access to the cable end (i.e., uncut looped fibre). This is not to be confused with an optical closure for blowing cable or fibre. This comprises an access housing that allows the interconnection of cable ducts or tubes and is attached to the ends of the ducts or cables containing empty tubes. However, BS EN 50411-2-3 is used when air blown fibres are spliced inside this type of closure. The fibre management closure provides facilities for environmental protection, housing for fibre management systems and sealing of input and output optical cables. In order to comply with BS EN 50411-2-3, the optical functionality, physical, geometrical, and mechanical requirements are defined. Using BS EN 50411-2-3 you can understand the initial, start of life dimensional, optical, mechanical, and environmental performance requirements of a fully installed sealed inline fibre splice closures Type 1 in order for it to be categorised as an EN standard product.
What’s changed since the last update?
BS EN 50411-2-3:2012 supersedes BS EN 50411-2-3:2007. BS EN 50411-2-3:2012 includes some technical changes with respect to BS EN 50411-2-3:2007. These include:
