摘要： When dynamic wavelength bandwidth allocation using a fixed cycle such as a multiple request method is realized in wavelength tunable WDM/TDM-PON, there is required a wavelength switching method that can suppress a transmission delay of an uplink signal and an increase in burst characteristics, that is, suppress an increase in an allocation cycle to a minimum.An ONU requests a bandwidth of an uplink signal, and in accordance with this, an OLT calculates a time when the OLT transmits the uplink signal and a transmission duration time and performs an instruction, and a DBA cycle in which the ONU transmits the uplink signal in accordance with the instruction and a dynamic wavelength allocation cycle in which the OLT instructs wavelength switching, and the ONU switches the wavelength and belongs to a different LC are separated. While the ONU switches the wavelength, the DBA cycles can be performed plural times in the ONU whose wavelength is not switched, the switching of the wavelength is confirmed after the wavelength has been switched, and then DBA operation is performed at the switched wavelength.
