Research of Cable Identification Method Based on Single Fiber

Qiang Sun, Qifu Wu

Abstract

Optical cable identification plays a very important role in cable maintenance and fault detection. In this paper, a new cable identification method based on optical fiber end reflection is proposed. Based on the theory of optical fiber sensor and phase modulation technology, single fiber optical cable identification is effectively achieved. System composition of this method is introduced in this paper. According to light interference principle, the expression of phase change when signal acts on fiber sensor is deduced; the relationship between redundant optical fiber and the system output signal is analyzed. The reasonable redundant fiber length is obtained by Matlab simulation, and the feasibility of the method is verified by experiment. Compared with other cable identification method, experimental results show that the single fiber optical cable identification has greatly improved in detection sensitivity and low maintenance time and costs.
