The standard applies to optical fibre cables for use with teleco mmunication equipment and devices employing similar techniques a nd to cables having a combination of both optical fibres and ele ctrical conductors. Presents requirements for the geometrical, t transmission, mechanical and climatic characteristics of optical fibre cables, and electrical requirements. This entirely revise d edition contains new measuring methods which were previously u nder consideration, such as torsion, snatch, kink, cable bend, t emperature cycling, sheath integrity and water penetration.
