Field test of a fully distributed fiber optic intrusion detection system for long-distance security monitoring of national borderline

Abstract

In this paper, we presented a successful field test of a fully distributed fiber-optical intrusion detection system for security monitoring of 220km long national borderline in China. Such a fiber fence shows its outstanding ability to operate at extreme weather conditions, like strong wind, heavy snow and storm, wide temperature range from -55℃ to +50℃, et al, which may be the most difficult and complicated environment for practical applications of fiber fences.
