Abstract:
Provided are a relay apparatus and a relay method for a passive optical network so as to largely extend a communicable distance while maintaining compatibility with existing network components. In the case of applying an optical relay to the passive optical network, a delay time is reduced by applying the optical relay so that entire transmission delay time considering the increased delay time may be within a preamble period of the upstream burst stream, thereby rapidly increasing a transmission distance of the passive optical network by using the optical relay.

Claim (Index 4):
A relay apparatus for a passive optical network which relays optical signals of an OLT and an ONT using a pair of optical transceivers, the relay apparatus comprising:\n a control unit that recovers an OLT clock from a downstream continuous signal to determine a clock of an upstream burst signal transmitted to the OLT, generates proactively an upstream burst frame preamble before the recovery of the clock and the data of the corresponding signal when the upstream burst signal is detected or predicted by a signal pattern to output the generated upstream burst frame preamble to the determined clock, and outputs all or some of the received upstream burst frame data when the upstream burst frame data is received through the burst mode clock and the data recovery as the determined clock subsequent to the upstream burst frame preamble which is proactively generated and output in advance.
