The development of a multi-parameter heterogeneous fiber sensor network based on fiber Bragg grating and Fabry-Perot

This paper proposes a heterogeneous structure of multiparameter optical fiber sensor network, which is composed of the quasidistributed temperature and strain sensor networks and the discrete pressure and vibration sensor networks. This network can multiplex different types of optical fiber sensors and can automatically identify the subnet type of the access network. We designed two structures of light source distribution and compared their advantages and disadvantages. The sensor network proposed in this paper provides a deliberate exploration for the construction of a large-capacity, large-scale, multiparameter, high-precision optical fiber sensor network.
