Abstract
A method for an adaptive forward error correction (FEC) in a passive optical network. The method comprises selecting an initial downstream FEC code to be applied on downstream data transmitted from an optical line terminal (OLT) to a plurality of optical network units (ONUs) of the PON; communicating the selected downstream FEC code to the plurality of ONUs; receiving at least one downstream bit error ratio (BER) value from at least one ONU of the plurality of ONUs, wherein the downstream BER value is measured respective to downstream data received at the at least one ONU; changing the selected downstream FEC code to a new downstream FEC code based on a plurality of downstream BER values measured by the at least one ONU; and communicating the new downstream FEC code to the plurality of ONUs.
