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 7):
A relay method for a passive optical network using an apparatus of relaying optical signals of an OLT and an ONT using a pair of optical transceivers, the relay method comprising:\n recovering, by a CDR unit configured in the relay apparatus, OLT clock data from a downstream continuous signal received by the optical transceiver connected to the OLT; providing, by a control unit configured in the relay apparatus, a proactive upstream burst frame preamble generated according to the OLT clock recovered by the CDR unit to the OLT-side optical transceiver when the upstream burst signal received by the optical transceiver connected with the ONT is detected or predicted by a signal pattern; recovering, by a BCDR unit configured in the relay apparatus, clock data from the upstream burst signal received by the optical transceiver and storing, by an asynchronous buffer unit, the recovered upstream burst frame data using the clock recovered by the BCDR unit as an input clock and the clock recovered by the CDR unit as an output clock; and selecting, by the control unit, all or some of the recovered upstream burst frame data stored in the asynchronous buffer unit to provide the selected upstream burst frame data to the optical transceiver connected with the OLT according to the OLT clock subsequent to the proactively generated upstream burst frame preamble.
