Abstract

Proposed is a wavelength-division multiplexed orthogonal frequency-division multiple access passive optical network (WDM-OFDMA-PON) for both wired and wireless OFDM signal access, by using a tunable generation scheme of a flat optical comb. 17 comb lines with 30 GHz space and no more than 0.5 dB flatness are obtained theoretically and experimentally. The obtained flat optical comb is used as the optical source for 17 WDM channels in the proposed WDM-OFDMA-PON. A 16-quadrature amplitude modulation OFDM signal achieving 10.85 Gbit/s traffic data is modulated onto each channel with double sideband modulation and the transmission for both wired and wireless access has been successfully demonstrated by experiment.
