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.
