    Long-Range Free-Space Optical Communication Research Challenges Dr. Scott A. Hamilton, MIT Lincoln Laboratory and Prof. Joseph M. Khan, Stanford University The substantial benefits of free-space optical (FSO) or laser communications (lasercom) have been well known to system designers for quite some time, c.f. [1]. The free-space channel, similar to the fiber channel, provides many benefits at optical frequencies compared to radio frequencies (RF) including extremely wide unregulated bandwidth and tightly confined beams (i.e. narrow beam divergence), both of which enable low size, weight and power (SWaP) terminals. However, significant challenges are still perceived: stochastic intensity fluctuations in a received optical signal after propagating through the atmosphere, power-starved link mode of operation, and narrow transmit beams that must be precisely pointed and tracked. Since the late 1970’s the United States [2], Europe [3] and Japan [4] have actively been developing FSO technology motivated primarily for long-haul spaceborne communication systems. While early efforts were focused on maturing FSO technology, the past decade has seen significant progress toward demonstrating the practicality of FSO for multiple applications. The first high-rate demonstration of FSO between a satellite in Geosynchronous (GEO) orbit and the ground was achieved by the US during the GeoLITE experiment in 2001. A short time later, the European Space Agency (ESA) demonstrated a 50- Mbps FSO link operating at 800-nm wavelengths between their Artemis GEO satellite and: i) another ESA spacecraft in Low-Earth orbit (LEO) in 2001 [5]; ii) a ground station located in Tenerife, Spain in 2001 [6]; and iii) an airplane flying at altitudes as low as 6,000 meters outfitted with an FSO terminal developed by France’s Astrium EADS in 2006 [7].

  • The Future of Fiber-Optic Computer Networks
    Fiber-Optic Computer Networks Paul E. Green, IBM T.J. Watson Research Center iber-optic communication is only 25 years old, but it would be difficult to exaggerate the impact it has already had on all branches of information transmission, from spans of a few meters to intercontinental distances. This strange technology, involving -of all things -the transmission of messages as pulses of light along an almost invisible thread of glass, is effectively taking over the role of guided transmission by copper and, to a modest extent, the role of unguided free-space radio and infrared transmission. If the medium itself is not strange enough, reflect on the form taken by the transmitter - the semiconductor laser diode. This device is usually no larger than a grain of sand and transmits milliwatts of infrared light - enough to send information at gigabits per second over long distances with an extremely low received bit-error rate. Yet, looking a little closer at how this supposedly revolutionary technology has been used to date, you come away with a sense that vast new unexploited opportunities await. The bandwidth is 10 orders of magnitude greater than that of phone lines (25,000 gigahertz versus 3 kilohertz), and the raw bit-error rate on the link is 10 orders of magnitude lower. Design points of are in place today (1 GHZ= io9 HZ). When you combine these numbers with the great potential for cost reductions, Fiber-optic networks it becomes clear that fiber is much more promising than anything that network architects have ever had to play with before and that a great deal more can be done have had a profound with photonic communication than is being done today.

  • A Survey on Optical Technologies for Iot, Smart Industry, and Smart Infrastructures
    Journal of Sensor and Actuator Networks Review A Survey on Optical Technologies for IoT, Smart Industry, and Smart Infrastructures Slavisa Aleksic Institute of Communications Engineering, Leipzig University of Telecommunications (HfTL), 04277 Leipzig, Germany; [email protected]; Tel.: +49-341-3062-212 Received: 1 July 2019; Accepted: 7 September 2019; Published: 17 September 2019 Abstract: In the Internet of Things (IoT), a huge number of sensors, actuators and other equipment for data acquisition and processing will be interconnected by means of an omnipresent communication network able to efficiently support heterogeneous transmission technologies and applications. On the one hand, advanced optical communication systems, which already play a significant role in modern networks, are currently evolving to meet very high requirements of modern applications. On the other hand, there are already many ways to utilize optical components and effects for building precise, efficient, and reliable sensors. Thus, optical technologies have the potential to greatly help in realizing future smart infrastructures and systems. This paper gives an overview of currently available and emerging optical technologies for sensing and communication applications and reviews their possible application in the context of the IoT for realizing smart systems and infrastructures. Keywords: optical technology; Internet of Things (IoT); optical sensors; optical communication systems and networks 1. Introduction The main prerequisite for implementing future smart city applications and systems is the existence of an efficient and reliable smart infrastructure. Such an infrastructure integrates in an efficient and reliable manner various basic infrastructures such as (i) water distribution systems, (ii) electricity grids, and (iii) transport infrastructure (roads, railways, trams, and metro) together with information technologies, distributed smart sensing systems, and communication networks.

  • Design and Optimization of Free Space Optical Networks
    Design and Optimization of Free Space Optical Networks by In Keun Son A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama December 13, 2010 Keywords: Free space optics, FSO, Network design, Network optimization Copyright 2010 by In Keun Son Approved by Shiwen Mao, Chair, Assistant Professor of Electrical and Computer Engineering Prathima Agrawal, Professor of Electrical and Computer Engineering Chwan–Hwa “John” Wu, Professor of Electrical and Computer Engineering Abstract Recent advances in wireless communication technologies and the explosive growth of the number and variety of mobile devices and multimedia applications motivate the development of next generation wireless networks, i.e., beyond 4G mobile systems. Indeed, the compelling demand for extensive coverage and high capacity has brought about a challenging problem to design adaptive and scalable network architectures. Some broadband wireless technologies, such as WiMAX, millimeter-wave, and free space optics (FSO), have been developed to meet this demand. Free space optics have emerged as a promising technology for next generation wireless broadband networks [1] [2]. FSO is a wireless telecommunication system that uses free space as transmission medium to transmit optical data at high bit rates. Compared with traditional wireless technologies, such optical wireless links have many advantages, including cost effectiveness, long transmission distance, license-free operation, interference immunity, high bandwidth, and so on. In this dissertation, we propose to design and optimize broadband wireless networks based on the FSO technology. We first provide a comprehensive survey of prior work. We classify prospective global FSO networks into three categories, and present current state of the art in the field and discuss the challenging issues and open problems.

Assuming no other architectural changes in deployment, this overlay demonstrated a significant growth lag between 800GbE and the observed growth curves. However, the 4× growth curve generated by a 1.6TbE solution would also lag all observed growth curves, except “Peering Traffic”. Furthermore, all of the underlying factors that drive a bandwidth explosion, including (1) the number of users, (2) increased access rates and methods, and (3) increased services all point to continuing growth in bandwidth.
