Abstract :
In this work, we propose a novel modulation of four-band OFDM channels within 10-GHz bandwidth in 40-Gb/s PON with 128 ONUs. Here, we first propose using multi-band OFDM modulation format applying in -0.7 chirp parameter Mach-Zehnder modulator (MZM) to improve and compensate the fiber dispersion and RF fading effects. Moreover, -0.37 dB power penalty at FEC level (BER of 3.8×10-3) is also observed after 20 km fiber transmission.
