Optical fibre cables Part 4-20: Aerial optical cables along electrical power lines - Family specification for ADSS (All Dielectric Self Supported) optical cables
 N EN 60794-4-20

 

Annotation

 

This part of IEC 60794, which is a family specification, covers optical telecommunication cables, commonly with single-mode fibres to be used primarily in overhead power lines applications. The cable may also be used in other overhead utility networks, such as for telephony or TV services. Requirements of the sectional specification IEC 60794-4 for aerial optical cables along electrical power lines are applicable to cables covered by this standard.

NOTE In some particular situations in the electrical industry, short overhead links can be also designed with multimode fibres.

The ADSS cable consists of single-mode optical fibres contained in one or more protective dielectric fibre optic units surrounded by or attached to suitable dielectric strength members and sheaths. The cable does not contain metallic components. An ADSS cable is designed to meet the optical and mechanical requirements under different types of installation, operating and environmental conditions and loading, as described in Annex B.

This standard covers the construction, mechanical, electrical, and optical performance, installation guidelines, acceptance criteria, test requirements, environmental considerations, and accessories compatibility for an all dielectric, self-supporting fibre optic (ADSS) cable. The standard provides both construction and performance requirements that ensure, within the guidelines of this standard, that the mechanical capabilities of the cable components and maintenance of optical fibre integrity and optical transmissions are proper.

This standard excludes any "lashed" or "wrapped" OPAC cables.
