A Single-Channel 160 Gbps PDM-OFDM Enabled Integrated SMF-FSO Transmission: Performance Evaluation under External Weather Conditions

This research work advocates hybridization of PDM with OFDM transmission technique in fiber-free space optics (FSO) integrated data communication system. Dual-polarized-32-1eve1-quadrature amplitude modulated (DP-32-QAM) signals are used to attain 160 Gbps transmission capacity. System’s transmission is analyzed for 50 km fixed fiber length and varying FSO link range based on the external weather factors and sustainable development BER and EVM% are the performance metrics used to evaluate the transmission performance. A reliable 160 Gbps transmission is achieved along3 km range for clear sky and 1100 m for dense fog. The performance is also analyzed for Chandigarh city weather conditions and reliable 160 Gbps1800 m transmission is reported for research precision.
