Abstract
The wavelength division multiplexed radio over free space optics (WDM RoFSO) system is a paramount candidate to provide extended range thus enabling efficient last mile connectivity. But the conventional design is unable to transmit the information up to larger distances under harsh climate conditions. An improved 16 channel WDM-RoFSO system is proposed and simulated which yields quality transmission for extended range under the attenuation of 5.8 dB/km, 7.7 dB/km, 9.2 dB/km and 26 dB/km for foggy and rainy conditions respectively. A radio frequency (RF) signal of 60 GHz is modulated over an optical signal carrier and successfully transported with cumulative 16 × 10 Gbps bit rate up to 3.75 km in foggy environment. The link range is augmented by 1.65 km, 0.9 km, 1.8 km & 1 km for light fog, moderate fog, moderate rainfall and heavy rainfall conditions respectively.
