摘要： A method for sending uplink burst data in a passive optical network (PON) system includes: sending a synchronization pattern of the uplink burst data, the synchronization pattern being of a length, which is an integer multiple of 66 bits, and being formed by connection of 66-bit unit gene blocks; sending a burst delimiter (BD) of the uplink burst data; sending a forward error correction (FEC)-protected data in the uplink burst data; and sending an end of burst (EOB) delimiter of the uplink burst data. The technical solutions in the embodiments allow the use of a less complex equalizer at the reception end of a high-speed PON system.
