Design of 20 Gbps bidirectional full-duplex real-time communication system on 220 GHz band

With the rapid growth of communication demand, the terahertz communication system has attracted more and more attention. The current terahertz communication system is difficult to realize long-distance bidirectional communication due to limited power and strong crosstalk. In this paper, a terahertz bidirectional real-time communication system is proposed, which can solve the problem of limited distance and interactive communication by using the duplex of terahertz amplifiers and terahertz frequencies. After simulation and extrapolation, the system can support up to 400 m 20 Gbps upstream and downstream fullduplex real-time communication.
