Fiber-laser-based sensor system with bus-ring architecture

This work develops and experimentally investigates a novel fiber-laser-based sensor system with a bus-ring architecture. The bus-ring architecture with a reconfigurable function is designed to overcome the poor reliability of the ring topology. Numerous ring subnets are used to serve many fiber Bragg grating sensors. The bus subnet simplifies the interrogation process and time slot assignment. The protection mechanism is illustrated with reference to various cases of multiple link failure. Finally, experimental results indicate that the proposed fiber-laser-based sensor system exhibits improved reliability and capacity of the over a large area with multi-point architecture.
