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.
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 (mmwave) 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)
High-speed demand driven by bandwidth-consuming applications, such as video streaming and cloud computing, is exceeding available network capacity, forcing operators to implement innovative technologies to increase the throughput offered to end users. In particular, passive optical networks (PONs) with a full-duplex capacity of 10 Gb/s over a 40-km span are(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)
Radio over Fiber (RoF) systems have emerged as a cost effective solution for future multigigabit wireless networks operating at millimeter wave (mm-wave) bands. Such networks are composed of three subsystems: a central station, an optical distribution network, and several remote base stations. The design of an RoF land access network is a very(More)
