Ethernet transmission over a 100 Gb/s real-time terahertz wireless link

In this paper, we evaluate the transmission performance of a real-time 100 Gb/s digital-coherent THz wireless link, operating on a 300-GHz carrier over a LoS distance of 0.5 m in a 2x2 MIMO configuration. Using a 100 Gb/s Ethernet traffic generator, we evaluate throughput, frame losses and latency for different frame sizes and payloads. The link shows a stable long-term performance as reported by pre-FEC BER measurements taken from the real-time modem's DSP over a period of 96 hours.
