Phase-Sensitive Optical Time Domain Reflectometer with Dual-Wavelength Probe Pulse
A dual-wavelength pulse strategy is proposed to reduce the fading phenomenon in a phase-sensitive optical time domain reflectometer ( ϕ -OTDR). The theoretical basis behind this dual-wavelength pulse strategy is presented and an experimental setup is described to help validate the proposed strategy....
