THE HOW'S AND WHY'S AND APPLICATIONS ON SONET/SDH--MINUS THE JARGON Intended for use in broadband ISDN and ATM networks, SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) have taken on a life of their own. As fiber optic cable becomes the standard for data transmission, telcos and other carriers are deploying more high-speed SONET/SDH technologies to support leased-line services such as DS-1 and DS-3. In search of ever-faster data speeds, leading corporations such as Boeing, AT&T, and Disney are moving their private global networks to a SONET/SDH infrastructure. THIS BOOK IS A MUST-READ IF-- * Your're at the point where technology turns to business and shoot-or-pass decisions get made * Staying on top of what's hot in communications is your job * You need to understand the growth and workings of SONET/SDH, but don't have time for MIT * You want to compare cots, potentials, and performance of SONET/SDH with other technologies * You'd like business-model case studies of DWDM (Dense Wavelength Division Multiplexing) and WDM (Wavelength Division Multiplexing) that make sense * You sell, market, or manage for a firm that develops SONET/SDH systems * You make career choices in telecom, Internet service, networking, or the upper echelons of any large business * You invest in communications equipment makers, service providers, or applications creators * You're a curious technophile who can't get enough insider details on new communications strategies, methods, and trends * You see that there's more sun in the winner's circle than in the also-ran column The easiest way to size up SONET/SDH for your network--or simply to better understand these rapidly expanding technologies--SONET/SDH DEMYSTIFIED is the ideal shortcut to the front edge of high-speed networking.

Provides up-to-date coverage of Sonet/SDH technology written at a level that will be understandable to technicians working in the telecommunications industry. Includes detailed examples of DWDM (dense wavelength division multiplexing) and WDM (wavelength division multiplexing)

This explanative book comprehensively uncovers the operation of SDH using the functional/atomic modelling techniques.

An expert guide to the new and emerging field of broadband circuits for optical fiber communication This exciting publication makes it easy for readers to enter into and deepen their knowledge of the new and emerging field of broadband circuits for optical fiber communication. The author's selection and organization of material have been developed, tested, and refined from his many industry courses and seminars. Five types of broadband circuits are discussed in detail: * Transimpedance amplifiers * Limiting amplifiers * Automatic gain control (AGC) amplifiers * Lasers drivers * Modulator drivers Essential background on optical fiber, photodetectors, lasers, modulators, and receiver theory is presented to help readers understand the system environment in which these broadband circuits operate. For each circuit type, the main specifications and their impact on system performance are explained and illustrated with numerical values. Next, the circuit concepts are discussed and illustrated with practical implementations. A broad range of circuits in MESFET, HFET, BJT, HBT, BiCMOS, and CMOS technologies is covered. Emphasis is on circuits for digital, continuous-mode transmission in the 2.5 to 40 Gb/s range, typically used in SONET, SDH, and Gigabit Ethernet applications. Burst-mode circuits for passive optical networks (PON) and analog circuits for hybrid fiber-coax (HFC) cable-TV applications also are discussed. Learning aids are provided throughout the text to help readers grasp and apply difficult concepts and techniques, including: * Chapter summaries that highlight the key points * Problem-and-answer sections to help readers apply their new knowledge * Research directions that point to exciting new technological breakthroughs on the horizon * Product examples that show the performance of actual broadband circuits * Appendices that cover eye diagrams, differential circuits, S parameters, transistors, and technologies * A bibliography that leads readers to more complete and in-depth treatment of specialized topics This is a superior learning tool for upper-level undergraduates and graduate-level students in circuit design and optical fiber communication. Unlike other texts that concentrate on analog circuits in general or mostly on optics, this text provides balanced coverage of electronic, optic, and system issues. Professionals in the fiber optic industry will find it an excellent reference, incorporating the latest technology and discoveries in the industry.

AN UNCONVENTIONAL, FUN WAY TO MASTER THE BASICS OF CRYPTOGRAPHY Cryptography is not just for specialists. Now every wireless message, wireless phone call, online transaction, and email is encrypted at one end and decrypted at the other. “Crypto” is part of the job description for network designers, network engineers, and telecom developers. If you need cryptography basics—but dread the thick tomes that are your only other option—help is at hand. Cryptography Demystified puts the fundamentals into a 35-module, learn-by-doing package that’s actually fun to use. You must read this book if— * You prefer your simplifications from an expert who understands the complexities * 6 years of success as a short course for students and professionals works for you * you enjoy hearing the phrase “nothing to memorize” * ecommerce, email, network security, or wireless communications is part of your bailiwick * cracking cryptography means a jump up the career ladder * the words “public-key cryptography,” “channel-based cryptography,” and “prime numbers” pique your interest * best-practices cryptography is the only secure way for you—and your company—to go One of the most complex subjects in Information Technology, cryptography gets its due in this down-to-earth, self-teaching tutorial—the first to make the basics of the science truly accessible.
