Paper Abstract

As we have already mentionned in the past, OTDR is a very interesting tool to monitor several ON/OFF sensors multiplexed along a single fiber. Indeed, Time Domain Multiplexing allows to easily monitor the time position of optical pulses reflected into a fiber line by optical microswitches or by any optical device whose reflection coefficient depends on a physical parameter (temperature, pressure, and son on). Moreover, such a technique allows to use very well known components such as pulsed laser diodes, couplers, avalanche photodiode and particularly multimode fiber whose commercial availability and reliability are now well established.
