| Summary: | 碩士 === 國立臺北科技大學 === 光電工程系研究所 === 101 === This paper develops and investigates mesh architecture for large-scale multipoint fiber sensor networks with high capacity and enhanced reconfigurable functionality. The main trunk of the proposed sensor system is a mesh and the sensing branches comprise a series of ring subnets. The proposed mesh topology is constructed by 2x2 optical switches to link the ring-based subnets in a meshed architecture and remote node composing four 2x2 optical switches to construct the links. Moreover, the scheme of fiber ring laser cooperated with the signal-averaging technology is applied in the proposed architecture to improve the signal-to-noise ratio （SNR）. The experimental results indicate that the proposed fiber-laser-based sensor system exhibits improved reliability and capacity of the large area with multipoint architecture.
