Abstract

Free space optics is a technology which uses beam of light to provide optical connection for transmitting and receiving purposes. For the increasing demand for high bandwidth in different network topology, FSO links has been a solution to the connectivity bottleneck problem. Transmitter consists of NRZ modulating CW laser with the link range 1 km in the wavelength 1310 nm or 1550 nm. When the signal is transmitted in the channel, the performance could be severely degrated due to atmospheric attenuation and earth inequalities. The purpose of this paper is to find a suitable filter for any of the two receivers i.e APD and PIN for the reduction of noise. Filters used are low pass Bessel filter, low pass butterworth filter, low pass Chebyshev filter.
