## Abstract

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.

## Claims

### Claim 1

A method for sending uplink burst data in a passive optical network (PON) system, the method comprising:
sending a synchronization pattern of the uplink burst data, wherein a length of the synchronization pattern is 66 bits; wherein the 66-bit synchronization pattern represented in a binary form is:
101111110100000010000110001010011110100011100100101101110110011010;
sending a burst delimiter (BD) of the uplink burst data;
sending forward error correction (FEC) protected data in the uplink burst data; and
sending an end of burst (BOB) delimiter of the uplink burst data.

### Claim 2

A device for providing uplink burst data in a passive optical network (PON) system, the device comprising:
a unit adapted to provide a synchronization pattern of the uplink burst data, wherein a length of the synchronization pattern is 66 bits; wherein the 66-bit synchronization pattern represented in a binary form is:
101111110100000010000110001010011110100011100100101101110110011010;
a unit adapted to provide a burst delimiter (BD) of the uplink burst data;
a unit adapted to provide forward error correction (FEC)-protected data in the uplink burst data; and
a unit adapted to provide an end of burst (EOB) delimiter of the uplink burst data.
