It is often necessary to detect a signal in an optical fiber by extracting a portion of the guided light. For example, one often wishes to be able to distinguish between live (signal carrying) and dark (no signal) fibers, to extract a signal for sampling (e.g. to detect a modulation tone for identification purposes), to perform an approximate measurement of the guided optical power, to perform accurate differential measurement of the guided optical power before and after a possible localized loss such as a splice, and to determine the direction of traffic. It is desirable to perform these operations without disrupting, overly attenuating or distorting the signal, especially in telecommunications systems, as the margins with which many such systems operate sometimes do not permit more than about 1 dB of additional attenuation without the risk of inducing errors on the signal.
