WAVELENGTH INDICATION IN MULTIPLE-WAVELENGTH PASSIVE OPTICAL NETWORKS Russian patent published in 2015 - IPC H04Q11/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to optical communication engineering and can be used in passive optical network devices. The device comprises an optical line terminal (OLT) component configured to connect to an optical network unit (ONU) and transmit downlink wavelength identification to the ONU to indicate a wavelength that corresponds to the ONU, wherein the downlink wavelength identification is transmitted using a media access control (MAC) layer frame for an embedded channel, a control message channel or a data channel. A PON network device comprises an ONU component configured to connect to the OLT and transmit uplink wavelength feedback to the OLT to indicate a wavelength that corresponds to the ONU, wherein the uplink wavelength feedback is transmitted using a MAC layer frame for an embedded channel, a control message channel or a data channel.

EFFECT: high transmission channel throughput.
