Abstract

In orthogonal frequency division multiple access-passive optical network (OFDMA-PON) uplink transmission with a direct detection system, the optical beat interference (OBI) noise is a very critical issue in regard to channel performance degradation. We have proposed a novel technique to suppress the OBI noise in intensity modulation and direct detection OFDMA-PON links by using an optical spectrum broadening method using the RF-clipping tone to improve the SNR of the discrete multitone modulation (DMT) signal with OBI noise suppression. We also experimentally analyzed the dependency of the RF clipping tone on the OBI noise suppression and dither effect. The results show that the received DMT signal in the optical line terminal can achieve 3 Gb/s over a 23 km SSMF with a BER of 2.3×10-4.
