N2 - To prevail against atmospheric attenuation considering unusual haze in tropical areas and to scale the growing demand for high capacity communication bandwidth and scalability, a prominent technique is used known as dense hybrid wavelength division multiplexing (DWDM)/multibeam free-space optics (FSO). In this study, attenuation arising due to haze scattering which is given as a function of link distance, wavelength and visibility is estimated from visibility data obtained from Malaysian meteorological department. Maximum attenuation of 20 dB/km has been observed due to unusual haze in Malaysia. This attenuation of 20 dB/km is applied on a proposed hybrid four channel of 1.5-Gb/s DWDM/multibeam FSO network with four wavelengths having standard downlink channel spacing of 100 GHz (~0.8 nm). The hybrid DWDM/multibeam FSO method has enhanced the performance of an FSO link in terms of the data rate, link distance, received power and scalability. The proposed approach facilitated access data to four end users at a data rate of 1.5 Gb/s each, over a link distance of 1,645 m at BER of 10 −9 under 20 dB/km attenuation.
