Optical beating interference (OBI) hinders signal detection in IM/DD based multiple access with single nominal wavelength. Optical pulse division multiplexing based OBI reduction is proposed and experimentally demonstrated in OFDMA-PON uplink by considering spectrum broadening and near-orthogonality.
