Abstract
The present study reports a spectral-efficient free-space optics communication link. Polarization division multiplexing-16-quadrature amplitude modulation and coherent detection-orthogonal frequency division multiplexing techniques are realized to attain 400 Gbps at 42 km for clear weather conditions. Further, we investigate the proposed link performance under varying level of fog weather conditions. The overall link performance is investigated by evaluating bit error rate, maximum link range, and receiver sensitivity.
