Optical Communication is a foundational reference covering the principles and applications of optics. The book offers a broad understanding of optics basics, the physics and mathematics behind the transmission of light, the devices that affect the passage of light, and the practical applications of optical theory in communications. It covers theoretical and practical applications of optical technology. The book demonstrates how the physics of optics translates into applications in telecommunications, optical communications in free space, and other media. This book:-- Offers a practical guide to optics and its applications in communications complementing existing works on its theory.-- Addresses the work of international standards bodies such as the ITU and ISO in aligning the physics behind the subject and the availability of standard products that can implement modern high-speed communications networks.-- Provides introductory concepts for those new to the field as well as students and professionals. This book is suitable for physicists, engineers, technicians, and chemists. Undergraduate students or anyone in the optical field who may need a grounding in associated applications or an early introduction to the field will find this book a valuable reference.
