What is BS EN 50411-2-2 - 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 50411-2-2 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.
Who is BS EN 50411-2-2 - Fibre organisers and closures to be used in optical fibre communication systems for?
BS EN 50411-2-2 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 50411-2-2 - 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 50411-2-2 defines optical closure comprising a closure housing that is attached to the ends of the joined cable sheaths and a means for containing and protecting the fibres, splices, and other passive optical devices.
BS EN 50411-2-2 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 50411-2-2, the optical functionality, physical, geometrical, and mechanical requirements are defined. The design of the closure housing allows the joining of two or more cable ends and its configurations or applications are track joint configuration used on trunk cable, with a minimum of 2 cable entries, spur joint configuration used on local feeder cable with a minimum of 3 cable entries and distribution joints have 4 cable entry port configurations used typically on FTTH customer feed cable with a minimum of 8, 18, 36, and 66 cable entry options. Using BS EN 50411-2-2 understand the initial, the start of life dimensional, optical, mechanical, and environmental performance requirements of a fully installed splice closure.
What’s changed since the last update?
BS EN 50411-2-2:2012 supersedes BS EN 50411-2-2:2007. BS EN 50411-2-2:2012 includes some technical changes with respect to BS EN 50411-2-2:2007. These include:
- The variant XX2 additional distribution closures with more cable entrance ports were defined (new versions D2, D3 and D4 were added)
- No other technical changes were made to the document
