Abstract
Provided are a system and method for setting a downstream forward error correction code for a downstream frame which is transmitted from an optical line terminal to an optical network unit in a time division multiplexing passive optical network. A system for setting a downstream forward error correction code in a time division multiplexing passive optical network includes: an optical line terminal configured to change a downstream forward error correction (FEC) indication included in a downstream frame and set a downstream FEC indication counter included in the downstream frame to transmit the downstream frame; and an optical network unit configured to receive the downstream frame from the optical line terminal and synchronize an FEC setting of the optical network unit with the FEC setting of the optical line terminal as a result of detection of the downstream FEC indication and downstream FEC indication counter included in the downstream frame.
