  • Patent number: 12028153
    Abstract: Provided are wavelength switching and configuration methods and devices for a Passive Optical Network (PON). The switching method includes the following operations. An Optical Network Unit (ONU) responds to a ranging request message sent by an Optical Line Terminal (OLT) on a first uplink wavelength supported by the ONU. The ONU receives ranging information sent by the OLT. The ONU uses the received ranging information as ranging information about a second uplink wavelength of the ONU, and performs data transmission on the second uplink wavelength according to a bandwidth allocation from the OLT. A path transmission time difference caused by a wavelength interval between the first uplink wavelength and the second uplink wavelength is less than a corresponding fault tolerance range when the OLT receives data. The ranging information is obtained by the OLT according to a ranging response sent by the ONU on the first uplink wavelength.
