We report ultra high dynamic range coherent optical time domain reflectometry employing frequency division multiplexing and frequency demultiplexing by software processing (FDM-OTDR). We improved a 5-dB dynamic range against conventional coherent OTDR, and achieved a 100-dB dynamic range with 218 measurements at a 1-km spatial resolution. |
