How does fiber optics work?

How does fiber optics work?

2021-08-09

The optical fiber for communication is composed of hair-like glass filaments covered with a plastic protective layer. The glass filament is essentially composed of two parts: the core diameter is 9 to 62.5 μm, and the outer cover is a low refractive index glass material with a diameter of 125 μm. Although there are some other types of optical fibers according to the materials used and different sizes, the most common ones are mentioned here. Light is transmitted in the core layer of the optical fiber in the form of "total internal reflection", which means that after the light enters one end of the optical fiber, it reflects back and forth between the core and cladding interface, and then transmits to the other end of the optical fiber. The fiber with a core diameter of 62.5μm and a cladding outer diameter of 125μm is called a 62.5/125μm fiber.
