Abstract

Free Space Optical (FSO) Communication is preferred over the radio frequency communication and microwave systems for about three decades. Next generation FSO communication systems use fiber-optic technology for unseamed and better data propagation rates. Besides license-free long-range operations, it has many other advantages like high bandwidth, small size, cheap and easy installation [1]. However, atmospheric turbulence highly influences the optical waves. As a result, it has few limitations like scintillation, dispersion of beam, etc. [2]. Such challenges are overcome by using different mediums and wavelengths. This paper considers the wavelength of 1550 nm with PRBS generator at bit rate 1. 25 Gb/s using both LASER and LED. These two optical sources are then compared on the grounds of Q-factor, Bit Error Rate (BER), wavelength spectrum and eye diagrams for the analysis of the sources that can be used in the FSO systems.
