Abstract
The present invention provides a method and a system for transmitting data. The OLT sets a multiframe indication and an upstream timeslot indication overhead in the downstream frame sent to the ONU. After receiving the downstream frame, the ONU determines the upstream bandwidth position according to the multiframe indication and the upstream timeslot indication overhead, and sends upstream data to the OLT from the upstream bandwidth position of the upstream frame. Through controlling the upstream data transmission by multiframes, each T-CONT carries an overhead area regardless of the length, and thus able to carry longer payload as against an equivalent overhead area in the prior art. In this way, the overhead area is saved and the bandwidth utilization is improved.
