A novel technique for mitigating the optical beat interference (OBI) noise in an optical orthogonal frequency division multiple access passive optical network (OFDMA-PON) uplink transmission is presented. By using an out of signal band RF clipping tone to the optical seed carrier, the OBI noise has been reduced and the resulting throughput and spectral… (More)
A novel technique for mitigating the OBI noise in optical OFDMA-PON uplink transmission is presented. By using out of signal band RF clipping tone to optical seed carrier, OBI noise has been reduced and resulting throughput and spectral efficiency has been doubled up.
A novel detection technique to eliminate the polarization mismatch for the stable OFDMA PON uplink multiple access transmission was proposed and experimentally demonstrated a stable transmission performance with 2 ONU uplink multiple access.
