WAVELENGTH NEGOTIATION METHOD AND APPARATUS OF MULTI-WAVELENGTH PASSIVE OPTICAL NETWORK, AND MULTI-WAVELENGTH PASSIVE OPTICAL NETWORK SYSTEM

摘要

This application provides a wavelength negotiation method of a multi-wavelength passive optical network, including: receiving a wavelength status table that is broadcast by an OLT over each downstream wavelength channel of a multi-wavelength PON system, where the wavelength status table is used to indicate information about available wavelengths of the multi-wavelength PON system and statistic information of registered ONUs of a corresponding wavelength channel; selecting an upstream transmit wavelength and a downstream receive wavelength according to the wavelength status table; and reporting information about the upstream transmit wavelength and information about the downstream receive wavelength to the OLT so that the OLT refreshes the wavelength status table. This application also provides a wavelength negotiation apparatus of the multi-wavelength passive optical network and a multi-wavelength passive optical network system.

1. A wavelength negotiation method of a multi-wavelength passive optical network PON, comprising:
receiving, by an optical network unit (ONU), parameters from an Optical line terminal (OLT), wherein the parameters correspond to wavelength channel of the multi-wavelength PON system; reporting, by the ONU, information about upstream working wavelength channel and downstream working wavelength to the OLT and an ONU wavelength capability set; wherein information about upstream working wavelength channel and a second information about downstream working wavelength are determined from the parameters; receiving, by the ONU, information about available wavelengths in transmit/receive wavelengths supported by the ONU from the OLT.
