Long-range single-mode OTDR, ultimate performance and potential uses
In Proceedings of the 10th European Conference on Optical Communication.
A high-performance single-mode optical time-domain reflectometer (OTDR) is described. Dynamic ranges of 30dB and 41dB one-way are achieved using laser diode and Nd:YAG laser sources respectively. A new OTDR technique allows absolute splice-loss measurements as well as active splice alignment to be performed from one cable end only.
