OPTICAL NETWORK UNIT SELF-CALIBRATION IN MULTI-WAVELENGTH PASSIVE OPTICAL NETWORK

摘要

A method and an apparatus for self-calibration of an ONU receiver in a multi-wavelength PON system, said method including the initial physical layer scan of the receiver tuning range, distributed estimation of the downstream wavelength channel drift with respect to the nominal standard-based wavelengths, and reporting the estimated downstream wavelength channel drift in the downstream Channel_Map message.
