Abstract

This paper proposes a star-bus topology optic fiber sensor network with an efficient mechanism for network communication to accomplish monitoring and protection operations. The master node scans each channel for its healthy conditions with an N * M optical switch, just as in time-division multiplexing, accomplishing a comprehensive monitoring of the whole sensor network. In addition, we analyze the impact of structural parameters on network robustness, then obtain a basic design principle of network topology. We also demonstrate the proposed network’s feasibility by multiplexing different fiber sensor systems simultaneously; in addition, an optimized structure is proposed to accomplish the measurement in extreme environments and proved to be effective.
