Pulse-Width Multiplexing ϕ-OTDR for Nuisance-Alarm Rate Reduction
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 data acquired at different pulse-widths are regar...
