“…The coherent optical/wireless network provides capacity greater than 40 Gb/s and thus, making signal useful for dual mode operation. A simplified RoF model is proposed in [7] using QAM transmitter. Although modulation format is complex, but it provides the transmission rate six times more than the signaling rate.…”

Radio over fiber (RoF) has found to be one of the most effective communication techniques. It has the tendency to incorporate both optical fiber and free space radio paths. In this research article, importance, benefits, and applications of RoF system are discussed in detail for futuristic networks. The performance of RoF system is visualized by modulating the data with the RF signal having same frequency at both transmitter and receiver ends. Initially, the performance is checked using non-return to zero (NRZ) format and later compared with duobinary (DB) and carrier suppressed return to zero (CSRZ). Various simulations are performed which directly affect the system performance. Important parameters such as RoF link distance, data rate, transmitter power, amplifier gain, and RF signal frequency are tested. The operation is carried out at 1550 nm wavelength and 30 GHz RF frequency. System is optimized to receive the transmitted waveforms successfully. Simulations are performed in Optisystem 17.0 and MATLAB. For the analysis, the results are plotted using Q-factor and BER values.

Visible light communication (VLC) is a new paradigm that could revolutionise the future of wireless communication. In VLC, information is transmitted through modulating the visible light spectrum (400–700 nm) that is used for illumination. Analytical and experimental work has shown the potential of VLC to provide high-speed data communication with the added advantage of improved energy efficiency and communication security/privacy. VLC is still in the early phase of research. There are fewer review articles published on this topic mostly addressing the physical layer research. Unlike other reviews, this article gives a system prespective of VLC along with the survey on existing literature and potential challenges toward the implementation and integration of VLC.

In this paper, a cost‐effective and simple full duplex RoF (radio over fiber) system is developed from a simplex coherent RoF. At the transmitter, utilizing the magnitude and phase of the vector carrier, four different information are encoded simultaneously on the carrier light wave. Dividing the total carrier power into two branches, enable the transmitter to modulate two distinct information on each branch. The working of the system is described in two main sections namely uplink section and downlink section. In the first section, encoding of uplink transmitting information and decoding downlink information at the central office (CO) is described. In the second section, modulating downlink transmitting information and demodulating coherently the uplink receiving information at the base station (BS) are described. An algorithm based on fast Fourier transform is described for effectively canceling the phase noise (PN) at the BS. Considering the cost of optical components, the source used to coherently detect the uplinked transmitted information, is again used as the carrier for downlink. Altogether, this system enables to transmit three different information on uplink and are faithfully received at the BS with an average of log(BER) value −23 dB. And for downlink, one information is transmitted and is successfully received at the CO with log(BER) of −9 dB. About 10 dB decrease in log(BER) values was found after the cancellation of PN.
