WAVELENGTH BANDWIDTH ALLOCATION METHOD

摘要

The present invention is a wavelength bandwidth allocation method characterized by including in the given order: a wavelength determination step (S4) for determining a plurality of wavelengths for uplink signals from each ONU to an OLT so as to guarantee a guaranteed bandwidth corresponding to the client service class of each ONU; and a reference bandwidth distribution step (S5) in which the entire bandwidth having the plurality of wavelengths determined in the wavelength determination step (S4) is distributed as reference bandwidth to each ONU in accordance with the client service class of each ONU, and the reference bandwidth of each ONU having the same client service class is made to be the same.
