Abstract
A method implemented by an optical network unit (ONU) in a passive optical network (PON). The method includes receiving an encoded downstream (DS) signal from an optical line terminal (OLT), searching for a physical synchronization sequence (PSync) pattern in all possible alignments for all possible OLT bit-interleaving modes within the downstream signal, and transitioning to a pre-synchronization state once the PSync pattern has been found.
