Abstract: The present document provides a method and apparatus for processing abnormal uplink data, herein, the method includes: a first time wavelength division multiplexing TWDM channel terminal in a TWDM passive optical network PON detecting abnormal uplink data; the first TWDM channel terminal sending uplink data abnormality information to other TWDM channel terminals in the TWDM PON, herein the uplink data abnormality information is used for the other TWDM channel terminals detecting whether uplink data sent by an optical network unit ONU managed by the other TWDM channel terminals are abnormal, and processing the ONU sending the abnormal uplink data when the abnormality is detected, solves the problem that an ONU sends data on a wrong uplink wavelength channel to cause uplink data interference on the uplink wavelength channel, and further achieves the effect of rapidly locating the ONU using the wrong uplink wavelength for communication.

Abstract: Provided are a ranging method and a communication method for an optical network, an Optical Line Terminal (OLT), an Optical Network Unit (ONU), and an optical network system. The OLT sends a broadcast message to the ONU, the broadcast message being used to indicate an uplink bandwidth allocated to the ONU. The OLT opens a quiet window for the ONU in a predetermined region. The OLT receives an uplink signal sent by the ONU at the quiet window.

Abstract: The disclosure provides a method and apparatus for adjusting wavelength for an Optical Line Terminal/Optical Network Unit (OLT/ONU). The method for adjusting wavelength for an OLT includes that: a source OLT sends an adjustment notification message to a target OLT, wherein the adjustment notification message is used for indicating that an ONU is to be adjusted into a Time-Wavelength Division Multiplexing Channel (TWDM CH) of the target OLT; and the source OLT receives an adjustment acknowledgement message provided by the target OLT, wherein the adjustment acknowledgement message is used for indicating that an adjustment process of the ONU has been completed. By means of the technical solution provided in the disclosure, an ONU of a source OLT can still work normally after being switched to a channel of a target OLT, thereby achieving the effect that the continuity of a service between the OLT and the ONU may be maintained.
