Free space optics is an optical wireless communication technology that uses space for transferring data between two given points. It is used in regions where physical links are not possible. By using Orthogonal Frequency Division Multiplexing (OFDM) is a modulation technique for transmission of communication through recent wireless and optical channel. The OFDM is a recent multiple access technology for both wired and wireless mediums. It provides the data on a large number of subcarrier which has been adapted to the recent broadband communication system. This research focus to carry out investigation of performance analysis of CO OFDM FSO system using Polarization Division Multiplexing as compare to WDM-FSO system under adverse weather condition. A 10 Gbps data is transmitted using 4-QAM through free air space under light rain, heavy rain and wet snow conditions. Results show that by employing polarization division multiplexing, CO-OFDM-FSO link prolongs to 17 km with acceptable bit error rate (BER≤10-9) under light rain conditions, while under heavy rain conditions, the maximum distance is extended to 6 km and CO-OFDM-FSO system using PDM provides enhanced values of quality factor.
