* Ideal for those with some background in communications but without previous knowledge of fiber optics * Provides a comprehensive treatment of the fundamentals of fiber optic systems and their individual components * Places emphasis on practical techniques of component installation and system designFiber Optics is a technology that uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. Fiber optics have several advantages over traditional metal communications lines. While there are plenty of theoretical texts on fiber optics, high-level engineering texts and installation guides, there are few comprehensive applied texts for practicing engineers. This book covers design issues, installation and troubleshooting in the right depth for engineers working in industry. Readers will use this knowledge to develop the required techniques for design, installation and maintenance of their own fiber optic systems.
An introduction to the essentials of fiber-optic systems for engineers and communications professionals.
