Abstract
An optical line terminal (OLT) accumulates and stores a user frame for each physical layer identifier (PLID) to efficiently use a plurality of lanes used for downstream transmission from the OLT to an optical network unit (ONU). The OLT envelopes payloads that are accumulatively stored for the respective PLIDs based on a transmission rate supported by a corresponding ONU, combines an envelope header based on an envelope payload unit, and transmits an envelope frame. The OLT selects an available lane from among a plurality of lanes and may transmit the envelope frame through the selected lane.
