| 摘要 |
An optical power transmission monitoring system for monitoring a multiplicity of transmission lines includes a first plurality n of optical sources; a second plurality m of optical detectors; means for time multiplexing each of the n sources through m different lines to the m detectors; and means for 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. |
