WDM-PON SYSTEM, ONT, OLT AND METHOD FOR INITIALIZATION OF TUNABLE LASER

摘要

A wavelength-multiplexed passive optical network (WDM-PON) and a method are described herein for setting-up (e.g., wavelength tuning, power tuning) an ONT laser by establishing a communications channel on an optical layer between an optical line terminal (OLT) and an optical network termination (ONT). The communications channel is established by utilizing the OLT's laser shutdown function and the ONT's signal detection function.
