Abstract
Free Space Optics (FSO) communication provides an attractive solution to bridge the gap between the existing fiber optics infrastructure and the end user. This paper investigates the System level design link of FSO by using different filters for the reduction of noise and timing error. The use of FSO links has been proposed as a solution to the connectivity bottleneck problem which has arisen from the ever increasing demand for high bandwidth in different network topology. Transmitter consist of NRZ modulating LED with a wavelength of 1550 nm and using positive intrinsic negative type photodiode as a receiver, the link range is 450 meters. The result shows the response of timing error, zero crossing distortion and SNR by using different filters.
