Abstract

Abstract In this paper, a hybrid DWDM/multiple-beam free space optics (FSO) communication link has been proposed consisting of 16 channels with the channel spacing of 100 GHz (0.8 nm) each transmitting at 2.5 Gbps bit rate. At the receiver terminal, an erbium-doped fiber amplifier (EDFA) is used to amplify the received signal. The results show an improved performance of hybrid DWDM/multiple-beam FSO link in terms of Q factor, received power, and link distance under rain attenuation of 19.2 dB/km. The proposed link design was able to transmit data from 16 channels, each transmitting at a bit rate of 2.5 Gbps along a link length of 2,300 m in FSO link under heavy rain weather conditions.
