A compelling treatment of FTTH Written by telecommunications pioneer Paul Green Jr., Fiber to the Home is a comprehensive examination of the technical and social implications of fiber to the home (FTTH), the technology that extends the current fiber optic backbone to optically connect it directly to homes and offices. Fiber to the Home addresses the payoffs expected from this impending technological revolution; provides a detailed guide to the optoelectronic components and architectures of which the system is made; and includes an equally thorough guide to the mechanics of deploying the fiber paths, whether underground or elevated. Additionally, the book concludes with a recent country-by-country survey of the legalities and the state of play in this important new trend. Green points out how completing the «last mile» between today's fiber network backbone and customer premises will not only unleash new usage modes for consumer computers, TVs, phones, and other terminal types, but will also empower both the computer and telecommunication industries toward new levels of investment and profitability. Aimed at a general audience, Fiber to the Home uses essentially no mathematics, and all terms are carefully explained and reinforced with a vocabulary quiz at the end of each chapter. Because of the tutorial emphasis of the explanations, the wide spectrum of readers affected by this emerging and ever-accelerating revolution will gain a thorough understanding of the technical details of FTTH that will aid them in the practice of their professions. These readers include: * Technicians, craftsmen, and engineers involved in installing fiber systems * Telecommunication network planners * Venture investors curious about the future of this dynamic industry sector * Research and product engineers who need to know the detailed architecture, cost, and performance imperatives of this «post-bubble» optical networking business opportunity * Students interested in a vibrant new industry with new jobs and new R & D challenges * Telecommunication regulators and attorneys who need a quick fix on what the technology is and what it does * Individuals concerned with international competitiveness in an age when the country's information infrastructure is such a key ingredient for future growth With Fiber to the Home, readers are armed with all they need to fully understand and participate in the FTTH revolution.

Коллективная монография посвящена средообразующей деятельности речного бобра – ключевого вида малых рек Приокско-Террасного заповедника. Изучение динамики численности и распределения бобров в водоемах заповедника проводится более 60 лет, с первых дней реинтродукции. Рассмотрены общие природные характеристики заповедника, включая климат, рельеф, гидрологическую сеть, характеристику флоры и фауны. Представлены особенности обитания речного бобра, включая детальное описание многолетней динамики численности с характеристикой изменения размещения поселений, строительной деятельности, особенностей кормодобывания, влияния хищников и вербальное описание изменения местообитаний на территории заповедника. Особое внимание уделено математическим моделям, предназначенным для выявления основных тенденций изменения численности и построения прогноза популяционной динамики с учетом особенностей экологии вида. Охарактеризованы различные аспекты влияния бобров на водные и околоводные экосистемы малой реки Таденки, даны количественные и качественные характеристики влияния деятельности бобра на зоопланктон, макрозообентос, размножение амфибий, динамику черноольшаника и высшую водную растительность в местообитаниях речного бобра. Обсуждаются потенциальные возможности применения космических снимков среднего (Landsat 7) и сверхвысокого (IKONOS, GeoEye-1) пространственного разрешения для картирования объектов жизнедеятельности бобров. Данная монография будет интересна и полезна широкому кругу ученых – зоологам, гидробиологам и ботаникам, специалистам, работающим на стыке геоматики и экологии. Знание средообразующей деятельности бобра важно для специалистов, работающих в области сохранения биологического разнообразия, заповедного дела и рыбного хозяйства, а также для студентов и аспирантов.

For years, fiber optics was the future. Now, it's the present, and the time has come to act if you want to make a career in this fast-growing field. The Fiber Optics Installer and Technician Guide is a comprehensive resource designed to prepare you for the two leading fiber optics certifications, Fiber Optics Installer (FOI) and Fiber Optics Technician (FOT). This book's practical, objective-focused coverage includes: The history of fiber optics Principles of fiber optic transmission Optical fiber characteristics, construction, and theory Safety considerations Cables, connectors, and splicing Fiber optic light sources and transmitters Fiber optic detectors and receivers Passive components and multiplexers Fiber optic links Testing equipment Techniques for testing links and cables Troubleshooting and restoration techniques Note: CD-ROM/DVD and other supplementary materials are not included as part of eBook file.

This book provides a comprehensive account of fiber-optic communication systems. The 3rd edition of this book is used worldwide as a textbook in many universities. This 4th edition incorporates recent advances that have occurred, in particular two new chapters. One deals with the advanced modulation formats (such as DPSK, QPSK, and QAM) that are increasingly being used for improving spectral efficiency of WDM lightwave systems. The second chapter focuses on new techniques such as all-optical regeneration that are under development and likely to be used in future communication systems. All other chapters are updated, as well.

This book will provide insight into the principles and applications of nonlinear effects in fibers for students, researchers, and developers who have a basic understanding of electromagnetic theory under their belts. It will explore the physics, limitations, applications, and research results surrounding nonlinear effects in fiber optics. In addition to communications, optical fibers are already used in medical procedures, automobiles, and aircraft and are expected to have many other applications. This will expand the range of industry workers who will find a book of this type useful.

A review of the various methodologies for the surface treatment of different types of inorganic spherical and fibrous fillers, describing ball milling, cationic polymerization, vapor phase grafting, plasma treatment and UV irradiation in detail. In addition, the book connects the resulting composite properties to the modified filler surface properties, thus allowing for a purposeful, application-oriented composite design.
