Fiber optics has become the backbone of all communications systems, including telecom - landline and wireless - the Internet, CATV, LANs, etc. All these fiber optic networks require testing to ensure they are installed properly and to troubleshoot problems when they arise. Fiber optic manufacturers and network users say that testing is the most important aspect of installation and operation but often the least well understood. This book has been written by the FOA to provide a comprehensive but understandable technical guide to this important topic. The Fiber Optic Association, Inc. (FOA) was founded in 1995 by a group of instructors who were highly experienced at teaching fiber optics. They represented educational institutions, manufacturers and commercial and government users of fiber optics, including all types of fiber optic applications. All were concerned about the absence of standards for teaching fiber optic technicians and industry certifications to show their competence. The FOA was chartered to promote fiber optics through education, certification and standards. Today the FOA is recognized around the world as the authority on fiber optic training and certification. The FOA has always tried to provide the world with sources of technically correct unbiased information on fiber optics using both print and electronic media. For such a broad subject as testing fiber optic networks, we depend on the FOA Online Reference Guide on the FOA website (www.foa.org), the largest and most widely used reference on fiber optics to supplement the material in this book. This book and the FOA Online Reference Guide provide a basic reference for testing fiber optic networks and a study guide for FOA Fiber Optic Specialist Certification in testing.

In Zukunft werden Milliarden "Dinge" über das Internet miteinander verbunden sein. Hierdurch entstehen jedoch auch gigantische Sicherheitsrisiken. In diesem Buch beschreibt der international renommierte IT-Sicherheitsexperte Nitesh Dhanjani, wie Geräte im Internet of Things von Angreifern missbraucht werden können – seien es drahtlose LED-Lampen, elektronische Türschlösser, Babyfone, Smart-TVs oder Autos mit Internetanbindung. Wenn Sie Anwendungen für Geräte entwickeln, die mit dem Internet verbunden sind, dann unterstützt Dhanjani Sie mit diesem Leitfaden bei der Erkennung und Behebung von Sicherheitslücken. Er erklärt Ihnen nicht nur, wie Sie Schwachstellen in IoT-Systemen identifizieren, sondern bietet Ihnen auch einen umfassenden Einblick in die Taktiken der Angreifer. In diesem Buch werden Sie • Design, Architektur und sicherheitstechnische Aspekte drahtloser Beleuchtungssysteme analysieren, • verstehen, wie elektronische Türschlösser geknackt werden, • Mängel im Sicherheitsaufbau von Babyfonen untersuchen, • die Sicherheitsfunktionen von Smart-Home-Geräten bewerten, • Schwachstellen von Smart-TVs kennenlernen, • Sicherheitslücken "intelligenter" Autos erforschen, • realistische Angriffsszenarios verstehen, die auf der gängigen Nutzung von IoT-Geräten durch Anwender beruhen. Darüber hinaus zeigt Ihnen Nitesh Dhanjani Prototyping-Methoden, die Sicherheitsfragen bereits bei den allerersten Entwürfen berücksichtigen. Schließlich erhalten Sie einen Ausblick auf neue Angriffsformen, denen IoTSysteme in Zukunft ausgesetzt sein werden. Stimmen zur Originalausgabe: "Dieses Buch enthüllt Sicherheitslücken, mit denen schon in naher Zukunft Milliarden vernetzter Geräte infiziert sein werden. Es bietet praktische Anleitungen zur Bewältigung aufkommender Sicherheitsrisiken für Verbraucher, Entwickler und Studierende gleichermaßen." Prof. em.

Fiber optics has become the backbone of all communications systems, including telecom - landline and wireless - the Internet, CATV, LANs, etc. Most books cover the installation of fiber optic networks, yet every network requires extensive planning and design to ensure a successful installation. This FOA book focuses on the design phase of a fiber optic network. It is aimed at the project manager, supervisor, owner, designer and installer of the network to inform them of the processes involved in the proper planning of a fiber optic communications project.

Depending on one's goals, v10 is: a guidebook for becoming a professional fiber installer, a training and reference manual for trainers and field supervisors, a manual for field installers, a study guide for passing basic and advanced certification examinations from the Fiber Optic Association [FOA], and an educational book for those interested in fiber optic communications. The information in PFOIv10 applies to data networks, data centers, telephone networks, fiber to the home networks, optical LANs, fiber to the antenna, distributed antenna systems, and CATV systems. This comprehensive manual supports achieving the five goals of installation for cables, connectors, splices, passive devices, and optoelectronics. This well-written and highly organized, 35 chapter, 496 page manual presents the concepts, numbers, product advantages, and installation and testing procedures required to achieve and verify the five goals of installation: low cost (do it right the first time), lowest possible optical power loss, low reflectance, short installation time, and high reliability. Chapters 1-9 detail essential information on available products, their most important performance parameters, and advantages of product types. This information sensitizes the installer to the capabilities and limitations of the products he installs. With this sensitivity, the installer understands how his actions influence power loss, reflectance, and reliability. Chapters 10-13 present the principles and methods of installation, through which the installer achieves the five goals. Chapters 14-20 detail testing and inspection principles and methods, which enable the installer to verify proper and reliable installation. Chapters 20-28 provide detailed, cookbook-like instructions for performing installation, inspection, and testing activities. By following the instructions in these 9 chapters, the installer develops 38 critical skills and abilities essential to achieving the five goals of a professional installer. Chapters 29-35 focus information in previous chapters on 7 applications: outside plant, fiber to the antenna, distributed antenna systems, fiber to the home [PON], data centers, optical LANs, and fiber characterization. Chapters 1-20 enable installers to pass the FOA CFOT basic certification examination. Chapters 10-17 and 29-35 enable installers to pass 10 of the FOA advanced certification [CFOS] examinations. PFOIv10 provides the trainer with tools for effective training: modular organization, 35 focused chapters, 749 review questions, 651 figures, and 75 tables. The modular organization facilitates training programs with multiple goals: basic skill development, advanced skill development, connector installation, splicing, inspection and testing. Finally, PFOIv10 includes 10 chapters of hands-on activities. PFOIv10 is based on the author's extensive field and training experience, which includes: Mr. Pearson has the following credentials: 39 years in fiber optics, 27 years of training manual development, 554 fiber presentations, 8886 fiber trainees, 49,728 connectors installed or supervised, 104,256 insertion loss tests supervised, 30,266 OTDR traces made or supervised, and 12 years as a Director of the FOA and developer of certification examinations. The author has been recognized as a Master Instructor by the FOA and, for 15 years, was a BICSI Master Instructor. He has degrees from Massachusetts Institute of Technology [BS] and Case-Western University [MS]. Both degrees are in Metallurgy and Materials Science.

Neoliberalismus ist eine Doktrin. Sie besagt, dass der Markt an sich eine Ethik darstellt und in der Lage ist, alles menschliche Tun und Trachten in die richtigen Bahnen zu lenken. Seit rund dreißig Jahren ist der Neoliberalismus aber auch politische Praxis, und viel ist darüber schon publiziert worden. Doch David Harvey legt mit diesem Buch das "lebendigste, lesenswerteste, verständlichste und kritischste Handbuch über den Neoliberalismus vor, das es derzeit gibt". (Leo Panitch, Professor für vergleichende politische Ökonomie an der York-Universität in Toronto) Harvey rekapituliert die Geschichte des Neoliberalismus, wobei nicht nur die allgemein bekannten "Pioniere" Thatcher und Reagan zu Ehren kommen, sondern auch das neoliberale "Modellland" Chile (unter Diktator Pinochet) oder das China des Deng Xiaoping. Er beschreibt den rasanten globalen Siegeszug der neoliberalen politischen Praxis in den 90er-Jahren und analysiert deren verheerende Auswirkungen in den meisten Ländern des Globus. Er zeigt aber auch anhand zahlreicher Beispiele, wie mit Zahlenmaterial gemogelt wird, um den "Erfolg" des Neoliberalismus zu beweisen. Nach diesem Buch wird das nicht mehr so einfach möglich sein.
