Claim:
1. A method of transmitting upstream burst data to an Optical Line Terminal (OLT) in a passive optical network system, the method comprising: detecting forward-error-correction (FEC) protected data in a first-in-first-out (FIFO) queue; transmitting a sync pattern sequence and a burst delimiter after turning on a laser; transmitting upstream burst data comprising the FEC protected data to be sent to the OLT; and transmitting an end-of-burst delimiter after the transmitting of upstream burst data has been completed, wherein the end-of-burst delimiter enables the OLT to determine the end of the upstream burst data and the end-of-burst delimiter comprises a binary sequence with alternating zeroes and ones that is 66 bits in length.
