“…On the receiver side, optimum photocurrent means providing sufficient LO power to saturate conversion loss, leading to improved receiver sensitivity and overall performance. In addition to BER and EVM, which are measured by comparing retrieved and transmitted sequences, the SNR is estimated from the BER result as follows for 16-QAM format [51] SNR(dB) = 20 log 10 10…”

Wireless communications at 300 GHz are expected to play an important role in the deployment of 6G and beyond networks. Multiple electronic and photonic technologies compete in this regard, each bringing its own particular benefits. While purely optoelectronic links are interesting for incorporating photonic advantages in signal transmission and reception, electronic receivers typically based on Schottky mixers are far superior in conversion efficiency. Thus, the link signal-to-noise ratio (SNR) is improved, and higher throughput can be achieved. Here, we demonstrate a fully optoelectronic 300 GHz band multi-channel link using a novel low-barrier Schottky mixer driven with a photonically generated local oscillator (LO) signal in the receiver using a modified uni-travelling-carrier photodiode (MUTC-PD). This combines the efficient down-conversion of Schottky-based mixers and the advantages of photonic LO signals such as tuneability, remote generation and distribution, and the reuse of coherent technology used in fibre networks. Up to three frequency channels are generated in the transmitter which is also based on a MUTC-PD photomixer, achieving a maximum aggregated line rate of 180 Gbps over 1.5 m under SD-FEC limit using 16-QAM format and optical intensity modulation. To the best of the authors' knowledge, this is an unprecedented data rate for fully optoelectronic terahertz communications.

“…As most of the time the data is transmitted from one point and received at another point found hundreds or thousands of km from the first it is advisable to use optical networks. Metropolitan networks use short-distance data transmission that can connect different networks, business centres, large nearby cities, etc [5].…”

The design of an optical system sets up the knowledge of the limitations dictated by the losses and dispersion in the optical fiber (in direct connection with the wavelength used) for a point-to-point connection. Except for short links used in local area networks, attenuation losses play a significant role in system design. The paper aims to analyse a fiber connection in terms of the best communication distance using Octave and Packet Tracer.
