    Abstract - (Show below) - (Hide below)

    Gives methods for measuring the length and elongation of optical fibres (typically within a cable). Length is fundemental for evaluation of transmission characteristics such as losses and bandwidths. Five methods are described: delay measurement, backscattering, fibre elongation, mechanical length, and phase shift.
