Abstract
Ultra-high-speed data transmission can be achieved through a combination of multiplexing techniques such as wavelength and polarization division multiplexing (WPDM). However, these systems are facing the two utmost constraints i.e. high cost and inter-channel interference (ISI). For the economical operations, optical comb generation (OCG) emerged as a promising technique for meeting the ever-increasing data demands in modern optical communication systems. On the other hand, an ISI can be suppressed using diverse pulse shapes in optical line terminal (OLT) for each transmitter referred as transmitter diversity (TRD). In this work, a reach enhanced and cost effective free space optical system (FSO) is presented by incorporating WPDM and TRD supporting 900 Gbps under different weather turbulences such as clear atmosphere (CA), rain and haze. The capacity is tripled by using three diverse angles of polarization (TDAP) such as horizontal, vertical and 45° tilted (45°T). Results revealed that the horizontal TDAP performed best and the proposed system can successfully covered 10 km under CA, 2.5 km under rain and 3.7 km under the effects of rain.
