A pulse-width multiplexing method for reducing the nuisance-alarm rate of a phase-sensitive optical time-domain reflectometer ( ϕ -OTDR) is described. In this method, light pulses of different pulse-widths are injected into the sensing fiber; the da

High nuisance alarm rates and missing alarm rates in phase-sensitive optical time-domain reflectometer ( ϕ -OTDR) greatly restrict their practical application. In this paper, an asynchronous sampling pulse width multiplexing ϕ -OTDR is proposed to
