Abstract

Swift demand of data rate supporting advanced number of end consumers at high speed has steered researchers to harvest Free Space Optics (FSO). This work is focused on engaging 2 × 10 Gbps return-zero (RZ) encoded wavelength-division (WDM) multiplexed Free Space Optics Communication system. The signal received is analyzed using BER analyzer and Eye diagrams
