  • Designing a Free Space Optical/Wireless Link
    Session: 2247 Designing A Free-Space Optical/Wireless Link Jai P. Agrawal, Omer Farook and C.R. Sekhar Department of Electrical and Computer Engineering Technology Purdue University Calumet Abstract This paper presents the design of a very high-speed data link between two buildings in a University campus that will operate at gigabit rates. The project uses a cutting edge technology of eye-safe laser communication through free space. This is an all-optical design is future-proof in regards to technological advancement in the rate of data transmission and introduction of newer protocols. The two buildings are approximately 500 meters apart. The free-space optical link uses 1550 nm wavelength in normal usage but has a wireless link operating at 2.4 GHz as the back-up. The line of site alignment will be achieved using telescopes initially but will have automatic tracking alignment system. The wireless back-up link is used only in very dense fog conditions. This paper presents the design of only the free-space optical connection, some parts of which are implemented in laboratory setup. I. Introduction The technology of establishing a high-speed networking between two buildings or campuses is one of the three: 1) copper wire, 2) wireless and 2) optical fiber technology. The copper technology is low-speed, labor-intensive and requires a regime of permissions. The advantages are high reliability and full availability. The wireless technology uses a few GHz carrier, is medium speed (up to few Gigabits per second), has small link span and requires a regime of licenses. Advantage is the ease of deployment.

    FIBER OPTICS Prof. R.K. Shevgaonkar Department of Electrical Engineering Indian Institute of Technology, Bombay Lecture: 25 Fiber Optic Link Design Fiber Optics, Prof. R.K. Shevgaonkar, Dept. of Electrical Engineering, IIT Bombay Page 1 The design criteria for a fiber optic link design procedure is mainly divided into broad categories which can be further subdivided as shown by the tree diagram below: Bit Rate (Dispersion Limitation) Primary Design Criteria Link Length (Attenuation Limitation) Modulation format eg. Analog/Digital Fiber Optic Link Design System Fidelity:BER, SNR Additional Design Cost: components, Parameters installation, maintainance Upgradeability Commercial Availability Figure 25.1: Fiber Optic Link Design Criteria The primary design criteria signify the most basic and fundamental information parameters to be made available by the user to the designer for designing a reliable fiber optic link. The first important information to be specified by the user is the desired bit rate of data transmission. However, the dispersion in the optical fiber exerts a limitation on the maximum achievable and realisable data rate of transmission. The next intricate information to be provided for the design process is the length of the optical link so as to enable the designer to ascertain the position of the optical repeaters along the link for a satisfactory optical data link. Along with the primary design criteria, there are some additional parameters which facilitate better design and quality analysis of the optical link. These factors consist of the scheme of modulation, the system fidelity, cost, upgradeability, commercial availability etc. A fundamental and very simple point-to-point optical communication link can be schematically drawn as shown in the figure below.

Kari Hiroyuki Minami Fujio Ohnishi Juha Saunavaara UNIVERSITY OF JYVÄSKYLÄ FACULTY OF INFORMATION TECHNOLOGY 2019 EXECUTIVE SUMMARY The submarine communication cables form a vast network on the seabed and transmit massive amounts of data across oceans. They provide over 95% of international tele- communications—not via satellites as is commonly assumed. The global submarine network is the “backbone” of the Internet, and enables the ubiquitous use of email, social media, phone and banking services. To these days no any other technology than submarine cables systems has not been such a strategic impact to our society without being known it as such by the people. This also means that it is at the same time a very interesting destination for hackers, cyber attackers, terrorist and state actors. They seek to gain access to information that goes through the networks of these continents that are connected to each other with sea cables. The main conclusion Tapping fiber optic cables to eavesdrop the information is a conscious threat.

While most broadband services around the world are delivered via copper access networks, op- tical access technology has been commercially available for sev- eral years and is being deployed in volume in some countries [1]. Where optical access is deployed, passive optical networks (PONs) are often the technology of choice because the trans- mission fiber and the central office equipment can be shared by a large number of customers. Early PON deployments were based on B-PON systems as standardized in the ITU-T G.983 series. Fig. 2. Mid-span GPON extension.

  • Inventing the Communications Revolution in Post-War Britain
    Information and Control: Inventing the Communications Revolution in Post-War Britain Jacob William Ward UCL PhD History of Science and Technology 1 I, Jacob William Ward, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 Abstract This thesis undertakes the first history of the post-war British telephone system, and addresses it through the lens of both actors’ and analysts’ emphases on the importance of ‘information’ and ‘control’. I explore both through a range of chapters on organisational history, laboratories, telephone exchanges, transmission technologies, futurology, transatlantic communications, and privatisation. The ideal of an ‘information network’ or an ‘information age’ is present to varying extents in all these chapters, as are deployments of different forms of control. The most pervasive, and controversial, form of control throughout this history is computer control, but I show that other forms of control, including environmental, spatial, and temporal, are all also important. I make three arguments: first, that the technological characteristics of the telephone system meant that its liberalisation and privatisation were much more ambiguous for competition and monopoly than expected; second, that information has been more important to the telephone system as an ideal to strive for, rather than the telephone system’s contribution to creating an apparent information age; third, that control is a more useful concept than information for analysing the history of the telephone system, but more work is needed to study the discursive significance of ‘control’ itself. 3 Acknowledgements There are many people to whom I owe thanks for making this thesis possible, and here I can only name some of them.

  • Optical Link Model White Paper
    The IEEE 802.3z Worst Case Link Model for Optical Physical Media Dependent Specification Development. Summary This document describes the IEEE 802.3z worst case link model for optical Physical Media Dependent (PMD) specification. The model is an extension of a previous worst case link model developed by Del (Delon) C. Hanson for the development of LED based links. The original model has been modified to include the effects of extinction ratio, relative intensity noise (RIN), mode partition noise (MPN) and intersymbol interference (ISI). David G. Cunningham & Mark Nowell, Hewlett-Packard Laboratories, Filton Road, Bristol BS 12 6QZ, UK and Del (Delon) C. Hanson, Hewlett-Packard Company, Communications Semiconductor Solutions Division, 350 W. Trimble Road, San Jose, CA 95131, USA and Professor. Leonid Kazovsky, Stanford University, Department of Electrical Engineering, Durand 202. MC-9515, Stanford, CA 94305-9515, USA. 1 Introduction In this document we develop a simple model which predicts the performance of laser based multimode optical fiber data communication links. The model has been developed as a tool to assist the IEEE 802.3z understand potential trade offs between the various link penalties and as a baseline for discussions on link specification. The model is an extension of previously reported models for LED based links [1,2]. Power penalties are calculated to account for the effects of intersymbol interference [3], mode partition noise [4], extinction ratio and relative intensity noise (RIN). In addition, a power penalty allocation is made for modal noise [5] and the power losses due to fiber attenuation, connectors and splices are considered. In the model we assume that the laser and multimode fiber impulse responses are Gaussian [2].

S. Institute of Technology and Science, Indore, India E-mail: [email protected] The technology of optical communication has gained importance due to high bandwidth and data rate requirements. The thrust areas of research under Optical Communications include Optical Wireless links, WDM, wavelength interleaving, newer modulation formats, etc. In recent, different scenarios of optical communication techniques like WDM, RoFSO, and bidirectional link and under water optical transmission are benefitted to utilizing optical bandwidth in the field of Free Space Optical communication (FSO). Free Space Optical (FSO) communication is capable of providing cable free communication at very high data rates up to Gbps. It is a growing area of research these days due to its low power, bandwidth scalability, unregulated spectrum, mass requirement, rapid speed of deployment and cost-effectiveness. Recent growth of FSO is evidenced by vast improvement in communication technology, resulting in investigations of many exciting simulative and experimental implementations. However, the system is influenced by unpredictable atmospheric and weather conditions, therefore it degrades the optical link performance. Current works are focusing on research trend and recent advancements in FSO communication. Solutions to make FSO an efficient technology, architecture for future mobile communication system are portrayed. The reliability of the FSO link can be improved by constructing atmospheric chamber as prototype to study free space channel and its characterization can be done under a controlled environment without the need for longer waiting times as would be in the case of outdoor FSO links.
