Multi-Gigabit Transmission over Multimode Optical Fibre

Sample

M. Oskar Deventer

Bidirectional transmission over optical fibre networks may yield a large cost reduction because of the reduction of the network infrastructure by a factor two and the potential cost reduction by an integrated transceiver design. It may also provide a cost-effective way to upgrade distribution networks by adding bidirectional channels. This book is the first to provide a comprehensive overview of bidirectional transmission in optical networks. It handles physical aspects: the behaviour of the fibre itself in bidirectional transmission transmission aspects: the behaviour and design of bidirectional systems and network aspects: the influence of bidirectional transmission on network design. £/LIST£ Practical guidelines are also given for bidirectional system design. Audience:This book is aimed at designers, builders and operators of optical networks, e.g. the manufacturers of optical transmission systems, public-network operators, developers of local-area networks, cable-television operators, etcetera. The intended level of readership is graduate level in physics or electrical engineering.

Describes the remarkable world of birds and their multitude of behaviours.Why do pigeons bob their heads when they walk? Can talking parrots understand what they say? What do birds learn and remember?Birds is an unusual collection of curious facts about our feathered friends. It describes the fascinating behaviours and physiology of birds of all shapes and sizes - from the birds in our cities to the wild birds in rainforests and at sea shores, in deserts and plains. You'll learn how birds evolved and why some came to be flightless. You'll read of the wide diversity in bird courtship rituals and territorial displays. You'll discover the art of nest building and why some birds have such well-developed senses and memory. In short, Birds explains why these creatures do the things that they do, so you can more fully enjoy and understand the birds you see every day.Gisela Kaplan and Lesley Rogers, two leading researchers in animal behaviour, cover the latest findings in bird behaviour and tell stories of their personal encounters with birds throughout the world, collected in more than twenty years of research. Supplemented with arresting photographs, this is a marvellous companion for the curious birdwatcher, the serious student of biology and for any nature or bird lover.

The essentials of XML in a short, easy-to-use format. The fastest way to learn the basics of XML! Covers the core concepts of XML without unnecessary background. Designed to introduce XML to readers with limited XML exposure. XML is the de-facto standard for manipulating and sharing data among applications. It is supported by every major programming tool and language, including Java, Microsoft .NET, Oracle, SQL Server, etc. All professional developers and administrators-- even those who don't intend to build XML applications--need a basic understanding of it just to read and maintain data they receive and process. Many of them don't have the time for a thick reference book or detailed tutorial. Sams Teach Yourself XML in 10 Minutes quickly covers the basics of XML and its family of related concepts, including basic syntax, DTDs, XML Schema, DOM, SAX, XSL and XPath. Each topic is illustrated with an example to ensure readers' understanding. Andrew H. Watt is an independent consultant and author with an expertise in XML technologies including XSLT and SVG. He most recently co-wrote Sams Teach Yourself JavaScript in 21 Days (0672322978) and previously wrote or contributed to several market-leading XML books, including Designing SVG Web Graphics (0735711666, New Riders), Professional XSL (1861003579), and Professional XML, Second Edition (1861005059), both for Wrox Press.
