What is BS EN 50407-3 - Multi-pair cables used in high bit rate digital access telecommunications networks about?
BS EN 50407 is a series on multi-pair cables used in high bit rate digital access telecommunications networks. Multi-pair cable is an electronic cable that consists of multiple groups of twisted-pair circuits. BS EN 50407-3 defines indoor multi-pair/quad cables for installation in Multi-Dwelling units shaft supporting universal services, xDSL and applications up to 100 MBits over IP, their relative definitions, and requirements.
BS EN 50407-3 covers cables, with an overall screen, with performances up to 100 MHz, to be used in indoor networks intended to connect the broadband outside plant to the individual customer dwelling for applications 100 Mbit/s over IP maximum length of connection 100 m. The electrical, environmental, mechanical and transmission performance characteristics of the cables, related to their reference test methods, are detailed.
Who is BS EN 50407-3 - Multi-pair cables used in high bit rate digital access telecommunications networks for?
BS EN 50407-3 on multi-pair cables used in high bit rate digital access telecommunications networks is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 50407-3 - Multi-pair cables used in high bit rate digital access telecommunications networks?
Multi-pair cables construction allows many wires to be bundled into one package, reducing electromagnetic interference and crosstalk, as well as providing easier installation. BS EN 50407-3 describes the cables that are designed for indoor high bit rate telecommunication networks. They shall have an overall screen. High bit-rate applications targeted in BS EN 50407-3 involve frequencies up to 100 MHz. To restrict emission and to ensure satisfactory electromagnetic immunity, these cables include an overall screen.
These cables contain from four pairs up to 100 pairs (FFS) that can be either in pair or quad construction. According to the EN 60068 (HD 323), for all test procedures described in BS EN 50407-3, the test conditions are in the standard atmospheric conditions – (23 ± 5) °C and 20 % −70 %, Relative Humidity –, unless otherwise stated. All measured and computed values are to be rounded to the number of decimal places given in the corresponding requirement or objective. The parameters specified in BS EN 50407-3 may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to a lack of suitable standards. Acceptance criteria are interpreted with respect to this consideration. Using BS EN 50407-3 you can define indoor multi-pair/quad cables for installation in Multi-Dwelling units shaft supporting universal services, xDSL and applications up to 100 MBits over IP, their relative definitions, and requirements.
