This paper presents the research work involved in the development of a knowledge-based framework for the design of millimeter-wave 60 GHz radio over fiber (RoF) land networks. It combines object-oriented, rule-based, technical information, and procedural functions to support engineers in the conceptual and preliminary design of a network. The overall framework is organized in two main modules: the first module is a tutorial of the terminology and basic principles in the design of RoF networks. The second module is a design assistant system that requests input data from the user about the functional network requirements and its prioritized figures of merit. The proposed design assistant is capable of providing support on the major activities of the 60 GHz RoF land network design such as downlink and uplink channel assignment and network clustering, wavelength allocation, optical link design, and network integration. The assistant is user interactive through the implementation of a graphical user interface. To illustrate the validation of such framework, we present a case of study of a network design with specific requirements.

“…Wavelength-division-multiplexed (WDM) ROF network is a powerful solution to provide a wide coverage of service areas [4,5]. We have proposed the use of a supercontinuum (SC) light source as a multiwavelength light source and a photonic up-conversion technique, which performs the frequency conversion from intermediate-frequency (IF)-band to radiofrequency (RF)-band through an optical link by taking advantage of the stability among the SC modes [6]. This would be a potential solution to install cost-effective central station (CS) and BSs for WDM ROF systems.…”

“…1 is the conceptual configuration of the dual-band ROF networks. The system consists of one CS, dualband and mm-wave-band BSs, remote nodes, and optical fiber links, in which ROF signals are transmitted with WDM technique, assuming a star topology [3,5,6]. To successfully perform the WDM ROF transmission, optical carriers must be individually assigned to BSs with different wavelength.…”

A wavelength-division-multiplexed transmission of dual-band radio-on-fiber signals using a supercontinuum light source is proposed. Error-free photonic up-conversion operation and simultaneous fiberoptic transmissions of 2.45-GHz-and 60-GHz-band signals using the dual-band compact base station prototype are demonstrated.Index Terms -Microwave, millimeter-wave, radio-onfiber, compact base station, supercontinuum light source, wavelength division multiplexing, photonic up-conversion.

“…Moreover, wavelength division multiplexing (WDM) is the promising way to further enhance the capacity [11], [12]. Many multichannel fiber-wireless links have been presented and experimentally demonstrated [13]- [17]. However, in order to allocate a number of wavelength channels, the cost and the complexity as well as the system stability inherent to the transmitters employing multi individual light resources will be a critical problem [18].…”

Four Sub-Channel Single Sideband Generation of Vector mm-Wave Based on an I/Q Modulator

et al. 2019

In this paper, a novel scheme to generate multichannel single sideband (SSB) optical signals enabled by one single I/Q modulator based on digital signal processing (DSP) is proposed, which is more flexibility and stability for the future 5G broadband access network instead of complex multiple lasers construction. Four sub-channels carrying different vector quadrature amplitude modulated (QAM) data are modulated to the upper sideband (USB) by I/Q modulation, while the vector unmodulated RF signal is located at the lower sideband (SSB) of the suppressed center carrier. They are used to generate four different mm-wave carriers after heterodyne beating. Due to the imbalance effect of I and Q components from the I/Q modulator, we also optimize the frequency of USB and LSB to reduce the crosstalk between the USB and LSB signal. The experimental results indicate that four-channel QPSK (2 × 2 × 4 = 16 Gbit/s) and 16-QAM (2 × 4 × 4 = 32 Gbit/s) signals with 5 GHz channel spacing at Q-band can be transmitted over 80 km single-mode-fiber 28 and 0.5 m wireless link without dispersion compensation.
