Embodiment approach 1
[0111] There are multiple TWDM channels in the TWDM PON system, each TWDM channel corresponds to a TWDM channel terminal and a group of ONUs, each TWDM channel corresponds to a downlink wavelength channel, and corresponds to one or more uplink wavelength channels. Different TWDM channels correspond to different downlink wavelength channels and different uplink wavelength channels. The OLT command is connected to each ONU in the PON system to work on a certain TWDM channel. The ONU uses the downlink wavelength channel corresponding to the above TWDM channel to receive downlink data, and uses the uplink wavelength channel corresponding to the above TWDM channel to send uplink data. After the ONU is powered on, if the ONU does not have a downstream wavelength calibration record, the ONU tunes its own receiving wavelength from low to high, or from high to low. The corresponding relationship between the current TWDM channel or the current downlink wavelength identifier completes th...
