What is BS EN 50411-3-8- Fibre management system about?
BS EN 50411-3-8 is a safety standard on fibre organizers and closures to be used in optical fibre communication systems.
BS EN 50411-3-8 specifies the dimensional, optical, mechanical, and environmental performance requirements of Terminal Equipment Boxes for the FTTX networks. The Terminal Equipment Box houses the ONT/CPE (electronics), and it protects the optical fibres, splices and connectors from direct contact with the user. Optionally it can contain the network test interface, the power supply and the batteries.
BS EN 50411-3-8 contains the initial, start of life optical, mechanical, and environmental performance requirements of the optical fibre termination in a Terminal Equipment Box. The tests selected combined with the severity and duration is representative of indoor and outside plants. The anticipated service life expectancy of the product in this environment is 20 years.
Note 1: The performance of the electronics, power supply or batteries are not part of BS EN 50411-3-8. These are covered by EN 50700.
Note 2: Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme.
Who is BS EN 50411-3-8- Fibre management system for?
BS EN 50411-3-8 on fibre management system, terminal equipment box is relevant to:
- Optical fibre technicians
- Suppliers of optical fibre
- Electromagnetic engineers
- Manufacturers of terminal equipment
- Testing authorities
Why should you use BS EN 50411-3-8- Fibre management system?
Fibre management system is a system to control fibre routing from the incoming to the out-going fibres, containing one or more splice cassettes and additional functional elements.
BS EN 50411-3-8 provides a means for routing, storing, and protecting fibre splices, connectors, or other passive optical devices in a predetermined order, from one cable sheath opening to another. BS EN 50411-3-8 assists with a test point that defines the service maintenance boundary of an access network at which external service providers may be assessed and which can be associated with protection devices. BS EN 50411-3-8 also assists with microduct system which is a system that provides routing air blown fibres or microduct fibre units, between hollow conduits (micro ducts), and interconnects the micro ducts by use of pneumatic connectors, tube welding, crimp connectors or push-on connectors.
The terminal equipment box provides:
- Facilities for mounting and protection of stored fibres, connectors, network test interface ENTI (optional), electronics (ONT/CPE), power supply (optional) and batteries (optional)
- Access by the user to the electrical data, CATV and telephone outputs
- A protected fibre management system for storing fibres, connectors, and splices
- Sealing of input and output optical and electrical cables
BS EN 50411-3-8 includes terminal equipment boxes used for micro duct cable or fibre. The design of the terminal equipment housing allows the jointing or termination of a minimum of one incoming cable to the specified number of optical connectors.
Overall, BS EN 50411-3-8 is useful as it aids on the product specifications and fibre management system, terminal equipment box type 1 for category C which can be helpful for your business.
