John Gowar’s text operates on the premise of a massive technological shift: the transition from traditional copper-based coaxial cables to optical fibers. In the mid-to-late 20th century, the exponential demand for data transmission pushed electrical systems to their physical limits. Optical communication offered a solution by using light as an electromagnetic carrier wave. Because the frequency of light is several orders of magnitude higher than radio frequencies, optical systems yield an unprecedented channel bandwidth. Gowar expertly bridges the gap between the physical properties of materials (how light interacts with glass and semiconductors) and the engineering systems required to transport data across them.
