Abstract
An ONU is provided. The ONU comprises a receiver configured to receive a first PON frame from an OLT, the first PON frame comprising a first PSBd field, the first PSBd field comprising a first PSync field, the first PSync field comprising first bits, and a first quantity of the first bits being greater than 64 bits; and a processor coupled to the receiver and configured to perform synchronization of the first PON frame by matching the first bits to a pre-stored sequence.
