Understanding Optical Fiber Communication by John Senior
Optical fiber communication is essentially the transmission of information as light pulses
along a glass or plastic fiber. John Senior’s approach to explaining this technology is both
accessible and thorough, making it easier for students, engineers, and tech enthusiasts to
grasp the underlying principles. At its core, optical fiber communication replaces
traditional copper wires with thin strands of glass or plastic, enabling data to move faster,
over longer distances, and with less signal degradation.
