Simulation and Analysis of Optical Communication System Using Different Channels
Abstract
Optical wireless has received major attention in the communication world due to growing demand for wireless broadband communication and overcrowding on bandwidth of RF spectrum. The performance analysis of an optical communication system with Single Mode Fiber (SMF), Free Space Optics (FSO), and Optical Wireless Communication (OWC) in different ranges where all the channels are operated at the same optical transmitted power with non-return-to-zero (NRZ) modulation has been analysed. The major problem in optical communication system is Strong atmospheric turbulence (disturbance due to rain, fog, haze etc.). Performance study is done for variable ranges 5, 7 and 10 km for the different channels at low bit rate 2.5Gb/s per channel. Comparison is made in terms of Q factor, BER and received optical power. It is concluded that the signal transmitted with has OWC system better Q factor, least BER and high received power as compared to SMF and OFC. .
