Abstract
Free space optical communication (FSO) provides high data rate by allowing light passed through the atmosphere. It is very effective and efficient technology for wireless communication. This emerging field basically uses invisible beams of light such as ultraviolet, infrared, etc. This work exclusively deals with the designing of hybrid WDM based FSO system using the simulation software Opti-System 7.0 with Minimum-Shift Keying and Differential-phase-shift keying. Further their study has been made as to which modulation techniques provides better means of communication. The normal rain weakening is assessed from rain power information which are gathered for a period for six months. The concert of the future system is evaluated in terms of Bit Error Rate, Q-factor, and Receiver Sensitivity are examined with respect to link distance for using rain attenuation 20.5dBm. The transmission wavelength and data rate is 1550nm and 2.5Gbps considered for investigation.
