We propose in this paper a self-referenced method based on asynchronous sampling to monitor the waveform of periodic and quasi-periodic signals, with a low number of samples, typically 2<sup>14</sup> or lower. It provides a high-resolution representation of the signal under test, representative of the analog intensity signal under test. Additionally, the(More)
—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)
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)
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)
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)
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.
Telecommunication operators are investing significant resources in developing passive optical networks (PONs) to meet the increasing capacity requirements. Therefore, wireless transmission has become the bottleneck for the wireless broadband internet access due to the spectrum saturation. This issue can be solved taking advantage of the huge portions 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 novel versatile digital signal processing (DSP)-based equalizer using support vector machine regression (SVR) is proposed for 16-quadrature amplitude modulated (16-QAM) coherent optical orthogonal frequency-division multiplexing (CO-OFDM) and experimentally compared to traditional DSP-based deterministic fiber-induced nonlinearity equalizers (NLEs),(More)
