Noise waveform reflectometer based on LED and spectral interferometry technique

The paper describes Noise waveform reflectometer of a new type, which uses wideband random signals and spectral interferometry method for fiber optical network diagnostics. Also correlation based reflectometer was submitted and investigated. These reflectometers have no so-called “dead zone” and are used for metrological support of fiber-optic communication lines (FOCL).
