Enhanced Performance Analysis of Multibeam FSO by Incorporating Carrier Supressed Return to Zero (CSRZ).

Free space optical communication (FSO) is thriving with greater pace nowadays due to its ability to support high speed, greater capacity, improved security, ease of installation, not having of Electromagnetic interference (EMI) and unlicensed spectrum. Atmospheric turbulence like Rain, Fog, and Haze is a prominent issue in FSO system that adversely affects the performance. This paper presents the demonstration of a multibeam FSO system operating at 1.25 Gbps in several haze types, including hazardous, very unhealthy, sensitive, good, moderate, and unhealthy. Additionally, BER and Q factor comparisons are made across three distinct pulse formats: carrier suppressed RZ (CSRZ), return to zero (RZ), and non-return to zero (NRZ). Utmost goal for the deployment of multibeam FSO is to get high received power and to compensate attenuation arising from haze effects. Results revealed that CSRZ performed exceptionally well as compared to NRZ and RZ. [ABSTRACT FROM AUTHOR]
