IEC 60794-1-20:2014 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. The object of this standard is to define test procedures to be used in establishing uniform requirements for the geometrical, transmission, material, mechanical, ageing (environmental exposure) and climatic properties of optical fibre cables, and electrical requirements where appropriate. Throughout this standard the wording 'optical cable' may also include optical fibre units, microduct fibre units, etc. Keywords: optical fibre test procedures, uniform requirements
