Aiming at the problem of low spatial resolution of Optical Time Domain Reflectometer (OTDR) in long distance optical fiber link detection, this paper proposes a new scheme of Linear Frequency Modulation (LFM) -Golay OTDR. The scheme improves the dynamic range and spatial resolution of the OTDR by ge...
