Applies to optical fibre cables which are tested at a particular tensile strength in order to examine the behaviour of attenuation and/or fibre strain as a function of the load on a cable which may occur during installation. This method is intended to be non-destructive (the tension applied sall be within the operational values). Two measuring methods are described below: - Method 501A: procedure for determining attenuation changes; - Method 501B: procedure for determining fibre elongation strain.
