Abstract

An optical power transmission monitoring system (10) for monitoring a multiplicity of transmission lines includes a first plurality n of optical sources (12); a second plurality m of optical detectors (20); time multiplexing each of the n sources through m different lines to the m detectors; and spatially multiplexing each of the m detectors through n different lines to the n sources for simultaneously sensing radiation at each detector through a transmission line from a unique source.
