Problems solved by technology

[0003] In the existing wavelength allocation scheme, random allocation is performed according to whether the wavelength is free and whether the wavelength is available for the ONU. Considering the discreteness of different ONU working states, this random allocation method may cause the wavelength tuning area of ​​the ONU to work in the Extreme working conditions will eventually lead to a large total power consumption of the TDM / WDM-PON system, and a short working life of the optical components of the ONU

Abstract

The present invention relates to a wavelength allocation method and a device. The wavelength allocation method comprises that an optical line terminal receives the operating parameter values transmitted by a current on-line optical network unit, the operational parameter values are N operating parameter values of a wavelength tuning area when the current on-line optical network unit utilizes N available wavelengths, the N operating parameter values correspond to N available wavelengths (N > 0); a wavelength is allocated to the current on-line optical network unit according to the operating parameter value; and instruction information is transmitted to the current on-line optical network unit, and the instruction information comprises the wavelength allocated to the current on-line optical network unit.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a wavelength allocation method and device. Background technique [0002] In Time Division Multiplexing / Wavelength Division Multiplexing-Passive Optical Network (TDM / WDM-PON) system, including Optical Line Terminal (OLT) and Optical Network Unit (Optical Network Unit, ONU). An OLT is connected to multiple ONUs, and the OLT allocates corresponding wavelengths to the channels of each ONU, so that the ONUs use the corresponding wavelengths to send and receive signals. [0003] In the existing wavelength allocation scheme, random allocation is performed according to whether the wavelength is free and whether the wavelength is available for the ONU. Considering the discreteness of different ONU working states, this random allocation method may cause the wavelength tuning area of ​​the ONU to work in the The extreme working state will eventually lead to a large total po...
