ITU-T Recommendations

ITU-T Recommendation G.667 contains parameters and definitions for devices providing adaptive chromatic dispersion compensation. These devices are needed for transmission and detection of optical signals in a system exhibiting high levels of dynamic variation of chromatic dispersion which would otherwise impair system operation. Single and multichannel line adaptive dispersion compensators are described, as well as single and multichannel adaptive dispersion compensating transmitters and receivers which may comprise electrical or optical forms of chromatic dispersion compensation. Information on single channel and multichannel adaptive chromatic dispersion compensation implementation, as well as principles of adaptive dispersion compensation, can be found in informative appendices.
