What is BS EN 50411-4-1 - Protective housings about?
BS EN 50411 is a series on fibre management systems and protective housings to be used in optical fibre communication systems. A fibre management system (FMS) manages optical fibre connections from outside of the fibre rack to the fibre routers. BS EN 50411-4-1 covers passive optical fibre street cabinets for use in outside plant environments under category A according to EN 61753-1. BS EN 50411-4-1 contains the dimensional, optical, mechanical, and environmental performance requirements of an installed passive optical fibre street cabinet, for it to be categorised as a European standard product.
BS EN 50411-4-1 allows EN 60793-2-50 single-mode fibres and EN 60793-2-10 A1-OM1 to A1-OM5 multimode fibres to be used and is suitable for all EN 60794 series optical fibre cables with their various fibre capacities, types, and designs if fitting in the cabinet does not contravene the minimum bend radius.
Who is BS EN 50411-4-1 - Protective housings for?
BS EN 50411-4-1 on fibre management systems are useful for:
- Telecommunication equipment and components manufacturers
- Design engineers
- Quality control personnel
- Research and development facilities
Why should you use BS EN 50411-4-1 - Protective housings?
The fibre management system is a process by which a fibre network is managed. BS EN 50411-4-1 describes passive optical fibre street cabinets as a protective housing containing a modular fibre management system with splice trays for various fibre separation levels and connector mounting plates. The optical fibre street cabinet may contain one or more storage and routing of fibre and cable, uncut (looped) fibre and cable storage, splice trays, adapters and connectors, passive optical components (optical power splitters and wavelength division multiplexers). Street cabinets can also contain active optical components (amplifiers, converters, power supplies).
The street cabinet has a means of containing and protecting the fibres, splices, connectors, passive optical splitters, and other passive optical devices, for example, WDM. Street cabinets used for blowing cable or fibre contain an area where the ends of the micro ducts or the protected micro-ducts, terminated with water and gas blocking, are placed. The design of the street cabinet may allow the joining together of at least one pair of cables that are not at the end of a cable section without cutting all fibres between both cable openings. BS EN 50411-4-1 is generally known as a mid-span or balloon splice configuration. Using BS EN 50411-4-1 you can understand the dimensional, optical, mechanical, and environmental performance requirements of an installed passive optical fibre street cabinet.
