Abstract
A novel optical beat interference (OBI) noise reduction technique for optical multiple access uplink using the same wavelength is presented. The OBI noise is estimated by similar-OBI and mitigated by subtracting estimated OBI noise using the digital signal processing technique. To derive similar-OBI, an RF clipping tone is transmitted out of signal band. We numerically and experimentally verified the validity of proposed OBI noise reduction method in orthogonal frequency division multiplexing access (OFDMA) passive optical network (PON) uplink where the OBI noise has been reduced and signal to noise ratio (SNR) has been improved from 4.4 dB to 10.6 dB.
