Overview of Optics and Optical Fiber Communication

This chapter provide a broad overview of optics and optical fiber communication, beginning with the historical development of fiber optic systems and progressing through the physical construction of fibers, cables, connectors, splicing techniques, and fabrication methods. Fundamental concepts such as light propagation in fibers, numerical aperture, acceptance angle, fiber classifications, and their technical specifications are explained to establish a strong conceptual foundation, reflecting the learning objectives outlined in the syllabus
