Burst mode optical repeater

A burst mode optical repeater comprising:

• a downstream optical signal repeater unit relaying an attenuated optical signal transmitted downstream by receiving the attenuated optical signal, amplifying the received optical signal, and outputting the amplified signal;
• an upstream optical signal repeater unit comprising an optical reception unit which receives an attenuated optical signal transmitted upstream from an optical network unit, an optical transmission unit which transmits the optical signal received by the optical reception unit to an optical line terminal, and a delay control unit which generates a burst enable signal based on a strength of the optical signal received by the optical reception unit and controls an optical signal, which is transmitted from the optical transmission unit, to have burst characteristics by using the burst enable signal;
• and
• signal splitting units which are installed at both ends of the burst mode optical repeater and split the optical signal transmitted downstream and the optical signal transmitted upstream so that the optical signal transmitted downstream and the optical signal transmitted upstream respectively pass through the downstream optical signal repeater unit and the upstream optical repeater unit.
