What is BS EN 60794-3-21 - Product specification for optical self-supporting aerial telecommunication cables about?
BS EN 60794-3-21 is a safety standard on optical fibre cables. BS EN 60794-3-21 is a product specification. BS EN 60794-3-21 presents the detailed requirements specific to optical self-supporting aerial telecommunication cables for use in premises cabling to ensure compatibility with ISO/IEC 11801 and ISO/IEC 24702.
Note: The requirements of the family specification IEC 60794-3-20 and sectional specification IEC 60794-3 are applicable to cables covered by BS EN 60794-3-21.
Who is BS EN 60794-3-21 - Product specification for optical self-supporting aerial telecommunication cables for?
BS EN 60794-3-21 on the product specification for optical self-supporting aerial telecommunication cables for use in premises cabling is relevant to:
- Optical fibre technicians
- Suppliers of optical fibre
- Testing authorities
- Manufacturers of outdoor cables
- Manufacturers of self-supporting aerial telecommunication cables
Why should you use BS EN 60794-3-21 - Product specification for optical self-supporting aerial telecommunication cables?
An optical fibre is a cylindrical dielectric waveguide that transmits light along its axis through the process of total internal reflection.
BS EN 60794-3-21 provides guidance on the attenuation of cabled fibre of the single-mode and multimode fibres, the fibre bandwidth requirements of the single-mode and multimode fibres and polarization mode dispersion (PMD) requirements.
Overall, BS EN 60794-3-21 is useful as it assists with the cables that are been tested, contains a full complement of working fibres.
