Product Description
Next-generation CATV systems: architecture, protocols, technologies, and applications. *Cable modems and digital set-top boxes: architecture and operation *HFC and its competitors: DSL, FTTL, DBS, and MMDS *Evolving from two-way HFC networks to next-generation DWDM access *Key applications: EPGs, IPPV, VOD, web browsing, e-mail, e-commerce, and more Broadband cable TV networks are undergoing a massive transformation, from simply broadcasting analog TV channels to providing sophisticated, two-way interactive services such as high-speed Internet access and video-on-demand. Now, one of the field's leading experts reviews the technologies, protocols, applications associated with the CATV revolution, and previews the migration path from today's two-way hybrid fiber/coax networks to the awesome capacities of tomorrow's DWDM fiber networks. Coverage includes: *HFC cable networks vs. the competition: DSL, FTTL, DBS, and MMDS *Key fiber-optics transmission technologies: directly and externally modulated laser transmitters, optical receivers, and Erbium-doped optical fiber amplifiers (EDFAs) *Architecture of DWDM access networks *Hardware architecture and operation of digital set-top boxes and cable modems *Software architecture and applications for digital set-top boxes Ovadia offers in-depth analyses of single and multiple-wavelength fiber-optics transmission impairments over HFC and DWDM networks, and presents the emerging two-way DWDM network architecture. Finally, he discusses the DOCSIS cable modem protocol, as well as key set-top box's applications such as electronic program guides (EPGs), video-on-demand (VOD), Internet-based applications such as e-mail, and e-commerce. Whether you're an engineer, scientist, cable professional, manager, or investor, if you want to understand where cable is headed, you need Cable TV Access Networks: From Technologies to Applications. Review
Cable television networks, since they have an enormous capacity to transmit analog and digital information and reach into almost every North American home, are being called upon to serve as the infrastructure for all sorts of consumer services. In Broadband Cable TV Access Networks: From Technologies to Applications, Intel Corporation expert Shlomo Ovadia explains the operation of cable television networks for the benefit of network designers, operations engineers, and people engaged in designing cable modems and other equipment. The approach in this book is detailed and specialized, but the clear writing style, attention to detail, and eagerness to explain how principles extrapolate out to customer services make it outstanding.

Ovadia approaches the subject through electrical engineering and electronics principles, illustrating explanations with circuit diagrams, oscilloscope traces, equations, and plots. Explanations of fundamentals are accompanied by discussions with block diagrams, and are dissected in ever greater detail.

While this book has done a great job of explaining, from a technical point of view, the increasing overlap of the cable television network with the switched telephone network and the Internet, be sure to read Telecommunications Convergence for a more (but not entirely) business-oriented look at the issue. --David Wall

Topics covered: Cable television networks and why they work, with emphasis on how they can be adapted for all sorts of last-mile broadband applications. Fundamentals are covered, such as lightwave transmitters and receivers, optical fiber amplifiers, RF digital quadrature amplitude modulation (QAM) modems, and the Data Over Cable Service Interface Specification (DOCSIS) protocol.
