Abstract

A star-bus-ring architecture for fiber Bragg grating (FBG) sensors is proposed and demonstrated. The FBG survivability and capacity of a multipoint sensor system are enhanced by adding remote nodes and 2 × 2 optical switches to the star-bus-ring architecture. Moreover, to enhance the signal-to-noise ratio (SNR) of the sensor system, we adopt a FBG laser scheme in constructing our proposed star-bus-ring architecture. The fiber laser adopted in this system resulted in an SNR of more than 50 dB for the sensor system. Finally, the network survivability is experimentally verified.
