—In recent years considerable attention has been devoted to the merging of radio frequency and optical fiber technologies aiming to the distribution of millimeter-wave (mm-wave) signals. This effort has given birth to the field of Radio over Fiber (RoF) technologies and systems. This sort of systems have a great potential to support secure, cost-effective,(More)
The peak-to-average power ratio (PAPR) and optical beat interference (OBI) effects are examined thoroughly in orthogonal frequency-division multiplexing access (OFDMA)-passive optical networks (PONs) at a signal bit rate up to $$\sim 20\,\mathrm{{Gb}}/{\hbox {s}}$$ ∼ 20 Gb / s per channel using cost-effective intensity-modulation and direct-detection(More)
We present a novel cost-efficient architecture based on a hybrid mode locked laser capable to simultaneously generate wavelength division multipliexed (WDM) passive optical network (PON) and radio over fiber (RoF) signals for 60 GHz applications. The proposed approach is compatible with the ITU frequency grid and does not require high bandwidth Mach-Zehnder(More)
A novel low-cost photonic PON-to-RoF bridge is presented, allowing simultaneous wireline and wireless multi-Gbps data transmission with minor impact on deployed PON networks. Simulation results show that the proposed scheme does not require narrow-linewidth lasers when envelope detector mobile terminals are used, since the transmission performance is not(More)
The sideband injection locking technique is studied for the first time to the authors' best knowledge as a way to generate orthogonal frequency division multiplexing (OFDM) signal at millimetric frequencies. Simulation results are presented to show its performance in terms of electrical modulation index, and electrical modulation frequency. The viability of(More)
A programmable optical router is a key enabler for dynamic service provisioning in Future Internet scenarios. It is equipped with optical switching hardware to forward information at hundreds of Gigabits/s rates and above, controlled and managed through modular and flexible procedures according to emerging standards. The possibility to test such costly(More)
A 2D Markov-Chain analysis is used to model channel occupancy within a high mobility picocell based network including handover and outage events. Single-cell performance is evaluated by the Grade of Service and by the call dropping probability. The relations between different picocellular network parameters are analyzed and guidelines for proper MAC(More)
Simulation results of the OSNR performance of an optical switch/router are presented in this paper. The paper is completed with a cascadability analysis, which takes into account the optical link that joins the nodes, and some results that show the effects of the scheduling algorithm on the optical performance.
The exponential traffic growth driven by high bandwidth applications such as video on demand and video gaming, is continuously forcing network operators to implement new schemes to increase the capacity offered to the end user. In particular, passive optical networks with a full-duplex capacity with 10 Gbps over 40-km spans are expected to be developed(More)
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(More)
