Long-distance OTDR using photon counting and large detection gates at telecom wavelength

Photon-counting OTDRs are typically used in a mode with spatial resolutions in the centimeter range. Here we demonstrate that their sensitivity and dynamic range can be enlarged using lower resolutions. A 44-dB dynamic range was experimentally obtained at a wavelength of 1550 nm. This represents a 4...
