IEC 60794-1-21:2015(E) 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 mechanical requirement performance. Throughout this standard the wording "optical cable" may also include optical fibre units, microduct fibre units, etc. General requi...view more

IEC 60793-1-43:2015 establishes uniform requirements for measuring the numerical aperture of optical fibre, thereby assisting in the inspection of fibres and cables for commercial purposes. The numerical aperture (NA) of categories A1, A2, A3 and A4 multimode fibre is an important parameter that describes a fibre's light-gathering ability. It is used to predict launching efficiency, joint loss at splices, and micro/macrobending performance. The numerical aperture is defined by measuring the far-...view more

IEC 60794-3-10:2015 which is part of a family specification, covers optical telecommunication cables to be used in ducts or direct buried applications. The cable may also be used for lashed aerial applications. Requirements of the sectional specification IEC 60794-3 for duct, buried and aerial cables are applicable to cables covered by this standard. This third edition cancels and replaces the second edition published in 2009 and constitutes a technical revision. This edition includes the follow...view more
