<p>Disclosed is a tuning method for a wavelength in a passive optical network, comprising: according to information reported by an optical network unit (ONU), an optical line terminal (OLT) allocating a wavelength to the ONU. Also disclosed is a tuning system for a wavelength in a passive optical network. The OLT is configured to allocate a wavelength to the ONU according to the information reported by the ONU. Also disclosed is a tuning device for a wavelength in a passive optical network, which is configured to report to the OLT information about at least one of the currently used wavelength of the ONU, the wavelength tuning range of the ONU and the time required for the wavelength tuning of the ONU, in the ONU wavelength tuning phase. The present invention is applied to solve the problem that alarms occur at the OLT side and the ONU side due to the fact that during the wavelength tuning of an ONU, the ONU cannot respond to the bandwidth allocated by the OLT or the wavelength allocation.</p> |
