Simulative Investigation of Long- Range 32x3 Gbps WDM-FSO Link Under Different Weather Attenuation Conditions

Pointing Error in FSO Link under Different Weather Conditions

125401-8686 IJVIPNS-IJENS © February 2012 IJENS I J E N S Abstract— Pointing errors is one of the main challenges that face free space optical communication and affects its performance specially at high range links, in this paper, an evaluation for the pointing error for practical Bit Error Rate is carried. This is done for an FSO link under different weather conditions at 1.55 μm. Under practi...

Reliability and Availability of FSO for different Weather Conditions

Today Free-Space Optical communication (FSO)has overcome the radio frequency communication. This paper gives an overview of the availability of an FSO system and its different weather conditions. It describes problems that the designer faces while implementing an FSO system and to overcome that problems .Performance analysis of a system for different weather conditions is carried out. Calculati...

Gbps data is transmitted over FSO link by applying WDM technique and compared with WDM-FSO system with Polarization Interleaving by varying the beam divergence angle from 1 mrad to 5 mrad. Next two FSO-WDM

111 www.ijeas.org  Abstract— This work is focused to carry out investigation of WDM Free Space Optical transmission when even and odd channels are orthogonally polarized. In this work 8 independent channels each having capacity of 1.56Gbps are transmitted over free space optical link of 15 kilometer at different beam divergence angles. Systems with and without polarization interleaving are com...

Performance Evaluation of FSO Link Under NRZ-RZ Line Codes, Different Weather Conditions and Receiver Types in the Presence of Pointing Errors

Performance evaluation for a free space optical (FSO) link with latest wireless optical communications (WOC) vendor’s networks specifications is presented. Analysis is performed for non return to zero (NRZ)-return to zero (RZ) line codes with various operating wavelengths using APD and PIN photodiodes receivers. The study includes the effect of atmospheric attenuation due to scattering effects ...
