Abstract
Abstract In this work, an optical hybrid communication system is proposed. It is a combination of diffused link (DL) configuration of free space optics (FSO) setup and fiber optic setup. It is a 16-channel dense wavelength division multiplexing (DWDM) system, with 400 Gbps/channel data rate. It uses dual polarization-quadrature phase shift keying (DP-QPSK) modulation technique for all the setups. Bit error rate (BER), eye diagram, quality actor (Q-factor), optical time domain reflectometer (OTDR), optical spectrum analyzer (OSA) signals are considered as performance parameters of the proposed system. It is found that the link distance is 340 m for DL setup and 1,000 km for fiber setup. The system will be very much useful for solving first mile, last mile problem with long distance optical communication applications in 5 G era.
