Abstract

Free Space Optics (FSO) is an emerging technology of this generation. FSO uses air as a medium for transmission channel. Free-space optics technology is an alternative of fiber optics technology. The main advantages of FSO communication system are it requires less installation time and it can save the required costs significantly compared to the implementation of fiber optics without losing the capability to send high data rates. In this paper we have designed a DWDM system using FSO channel. The designed system is using Mach-Zehnder modulator as it modulates the electrical signal directly into optical signal. The performance of the FSO transmission system is evaluated in terms of Q factor and BER values. The DWDM system using FSO channel is evaluated for high data rates i.e. 1Gbps to 10Gbps.The system performance is analyzed in terms of power transmitted and received using power meter.
