Abstract :
In this work, we investigate a hybrid OFDM-baseband (BB) signal and three-band OFDM wireless channels using the 2.5 GHz bandwidth directly modulated laser (DML) and 10 GHz bandwidth electro-absorption modulated laser (EML) in a passive optical network (PON) respectively. Here, each 16-QAM OFDM wireless and 64-QAM OFDM-BB signals can achieve 11.2 Gb/s and 15 Gb/s traffic data rates respectively in 20 km fiber transmission. To reduce the cost, the direct detection method is used. Moreover, the network performance has also been analyzed and discussed.
