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

Abstract

© 2017 SERSC. Objective: To design and investigate long range efficient 32-channel WDM-FSO system under worst weather conditions at data rate of 3Gb/s. Methods/Statistical Analysis: In this paper, 32 channel WDM-FSO system has been designed and investigated under worst weather conditions using NRZ modulation at 3Gb/s. Opti-system software is used to simulate the system. Findings: In this paper, the WDM-FSO system investigated under worst weather conditions using NRZ modulation in terms of Bit error rate and quality factor at 3Gb/s and also achieved the maximum possible link range with minimum target value of Bit Error Rate (BER) by using semiconductor optical amplifier. The present system supports the transmission up to 431 km that is achieved under clear weather condition at BER of 10-10. Application/Improvements: Results showed the maximum link range under worst channel conditions with minimum acceptable bit error rate By using the SOA pre-amplification at receiver side.
