What is BS EN 50411-3-5 - 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 is a high-speed data transfer protocol providing in-order, lossless delivery of raw block data. BS EN 50411-3-5 covers wall outlets for up to 4 SC foot-print adapters. Various connector types (e.g., SC, LC) can be implemented as long as the adapter fits in the SC footprint dimensions. A Wall Outlet is the passive end connection point of a fixed Single Mode fibre-based FTTH network to the flexible network of service unit (CPE, ONT) indoors. Products defined by IEV 442-08-02 or IEV 723-09-22 can be considered as Wall Outlets.
BS EN 50411-3-5 covers the possibility of using hybrid (fibre/copper) wall outlets with a 1 RJ-45 footprint. Wall outlets covered in BS EN 50411-3-5 will include a fibre management system (FMS) for managing the incoming cables or fibres. The FMS may include trays for splicing pigtails to incoming cable/fibre. BS EN 50411-3-5 contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements of an optical fibre wall outlet, in order for it to be categorized as a European Standard product.
Note 1: SI or ENTI are not part of this wall outlet specification.
Note 2: Performance of copper cabling and connectivity is not in the scope of BS EN 50411-3-5 but should be verified in line with EN 50346.
Who is BS EN 50411-3-5 - Fibre organisers and closures to be used in optical fibre communication systems for?
BS EN 50411-3-5 on fibre organisers and closures to be used in optical fibre communication systems is useful for:
- Telecommunication component manufacturers

- Design engineers
- Quality control personnel
Why should you use BS EN 50411-3-5 - Fibre organisers and closures to be used in optical fibre communication systems?
An electrical outlet is the source of electrical power you use to plug in many of your appliances, which is how you create that circuit in your home. BS EN 50411-3-5 describes Wall outlets that are placed in end-user premises by installers and the contents are not intended to be user-accessible. Wall outlets may be mounted using a number of techniques: surface mounted on a wall, patress boxes, trunking or raceway; flush mounted or between cable trunking. Cable entry points vary with mounting method: surface mounted or flush mounted boxes may require large holes at the rear of the wall outlet for cable entry requiring little or no strain relief, whereas boxes with cable entry visible to the end-user will need cable sealing and strain relief.
The wall outlet provides facilities for environmental protection, housing for a fibre management system, and prevention of ingress of objects larger than 1 mm in diameter. BS EN 50411-3-5 also discusses wall outlets used for blowing micro duct cable or fibre. The design of a wall outlet housing that allows the joining of a minimum of one incoming cable to the specified numbers of outputs. It is desirable that the wall outlet can be re-opened, when necessary, without interruption or disturbance of the traffic of the live circuits. Using BS EN 50411-3-5 you can specify wall outlets for up to 4 SC foot-print adapters.
