Comprehensive. The first course, Fiber Optics I –Theory, is an overview of the technology of fiber optic cables including a description of the components, history, and advantages of fiber optic cables. This course also discusses the electromagnetic theory of light and describes the properties of light reflection. The manual is intended as a guide for technologists, middle-level management, as well as regulators, to assist in the practical installation of optical fibre-based systems. Optical fiber and cable manufacturing equipment are closely related to the optical fiber and cable. These are the "outside vapor deposition" (OVD) process developed by Coming Glass Works and the "vertical axial deposition" (VAD) version developed by a consortium of Japanese cable makers and Nippon Telephone and Telegraph Corporation. The OVD process is one of the most common techniques used. Fiber optic tools are specialized instruments designed for installing, terminating, splicing, testing, and maintaining fiber optic cables.
