Abstract

A hybrid OFDM-baseband (BB) signal and three-band OFDM wireless channels using the 2.5 GHz bandwidth directly modulated laser and 10 GHz bandwidth electroabsorption modulated laser in a passive optical network (PON) is investigated. Each 16-QAM OFDM wireless and 64-QAM OFDM-BB signals can achieve 11.2 and 15 Gbit/s traffic data rates, respectively, in 20 km fibre transmissions. Moreover, the network performance has also been analysed and discussed.
