Abstract
A computer-implemented method of handling Ethernet packets in a passive optical network (PON) is disclosed. The method comprises generating, by the one or more processors, an initial envelope header that indicates that the initial envelope header is not a preamble replacement; transmitting, over the PON, by the one or more processors, the initial envelope header; accessing, by the one or more processors, an eight-byte block from a first Ethernet packet of a plurality of Ethernet packets; in response to the eight-byte block being an Ethernet preamble, generating, by the one or more processors, a first envelope header that indicates that the envelope header is a preamble replacement; and transmitting, over the PON, by the one or more processors, the first envelope header.
