Abstract

A self-healing passive fiber Bragg grating (FBG) sensor network (SN) is presented in this paper. The self-healing network consists of a star subnet and a ring subnet. The self-healing ability with single and multiple fiber link failures is theoretically analyzed. In addition, the self-healing function under different network statuses is experimentally demonstrated. A quantitative method for determining the status of FBG sensing signals is presented based on experimental observations, and a threshold of intensity for the FBG sensors in the FBG SN is given.
