A practical, applied introduction to fiber optics that takes a straightforward, non-mathematical approach to coverage. Gearing his narrative, explanations, and examples specifically to the technician-level student, this author provides a complete picture of fiber optics components and applications, along with the theoretical foundation needed for later courses. His approach is based on ray tracing, which is geometric in nature, without reliance on physics or complex mathematics. (Where ray tracing is not applicable, the results of other analysis methods are used, and explained, without their derivation). The result is a text whose depth and breadth is particulary suited to the beginning technology student.
