  • Long-Range Free-Space Optical Communication Research Challenges Dr
    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.

  • 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.

Chaudhry and Halim Yanikomeroglu Department of Systems and Computer Engineering, Carleton University, Ottawa, Canada – K1S 5B6 Abstract–Free space optics (FSO) refers to optical wireless communications in outdoor environments. The aim of this paper is to analyze the role that FSO is envisaged to play in the creation of next-generation satellite networks. To begin with, the reader is introduced to the types of FSO links and functionalities of a basic FSO system. Next, a comparison of FSO and radio frequency (RF) technologies for inter-satellite links (ISLs) is provided, including a comparison between FSO and RF links when employed between low Earth orbit satellites. After that, the types of FSO or laser ISLs are considered, and the challenges in establishing laser ISLs, the properties of laser ISLs, and the capabilities of terminals for laser ISLs are discussed. Then, the parameters of a satellite constellation are highlighted, and different aspects of SpaceX’s upcoming mega- constellation Starlink are explored. In addition, the optical wireless satellite network that is created by utilizing laser ISLs is examined. Finally, a use case is investigated for next-generation optical wireless satellite networks that are envisioned by the mid to late 2020s. WHAT IS FREE SPACE OPTICS? foundation for today’s FSO came with the discovery of the first working laser in 1960.

  • The Key Benefits of OTN Networks Introduction Optical Transport Networks Have Been Migrating from SONET Technology to WDM Architectures Over the Past 5–10 Years
    The Key Benefits of OTN Networks Introduction Optical transport networks have been migrating from SONET technology to WDM architectures over the past 5–10 years. Deploying WDM systems has allowed carriers to tap enormous capacity by carrying multiple wavelengths over a single fiber. For carriers, this means significant cost savings compared to the cost of deploying single-channel networks, or of overlaying multiple networks for each service offering. As this transition to WDM architectures occurred, it became painfully obvious that early WDM implementations lacked many key features required to properly operate and maintain these optical networks. With early WDM platforms many features, such as performance monitoring, fault detection and isolation, a standard multiplexing hierarchy and standard communication channels, were either missing or implemented in a proprietary fashion by each WDM equipment vendor. The Optical Transport Network (OTN) standards, defined by the ITU-T G.709 standards committee, were developed to add SONET-like performance monitoring, fault detection, communication channels, and multiplexing hierarchy to WDM wavelengths. The primary benefits of OTN include: • Enhanced OAM for wavelengths • Universal container supporting any service type • Standard multiplexing hierarchy • End-to-end optical transport transparency of customer traffic • Multi-level path OAM WDM Issues – The Need for OTN Standards The benefits that made SONET a robust optical transport technology, including a standardized mapping of client signals, enhanced performance monitoring at multiple layers, comprehensive fault detection and isolation, and embedded communications channels, were all missing from early WDM networks. Each vendor implemented their own proprietary methods of mapping client traffic, of detecting/isolating alarm faults, and of providing optical performance monitoring.
