In recent years, optical time-domain reflectometry (OTDR) has progressed from a laboratory experiment to a technique in everyday use by manufacturers and users of optical fibres. The principal attraction of the technique is its ability to give, non destructively, a good indication of the fibre-loss uniformity and therefore to reveal any localised defects in the fibre. It has also been employed as a means of measuring accurately fibre and splice losses, and of studying the longitudinal variation of fibre parameters.
