1. Principle of light guidance
An optical fiber is a thin glass cylinder in which light is trapped by total internal reflection. To understand how light propagates in a fiber, we can consider a geometrically simpler system, the symmetrical planar waveguide, consisting of a planar layer of a medium of refractive index n 1 sandwiched between two layers of a medium of index n 2 less than n 1 . The main properties are then transposed to the case of cylindrical optical fiber. We first describe the characteristics of the waveguide (§ 1.1 ...

A handful of major manufacturers share the worldwide market for optical fibers and cables for long-distance telecommunications networks. These "generalist" groups manufacture just about every type of fiber used in telecommunications, and are capable of producing thousands of kilometers of fiber.
