Refraction in fiber optics refers to the change in direction of light as it passes between materials of different optical densities—specifically, from air into the fiber optic core, and between the core and cladding within the fiber.

This bending of light is governed by Snell’s Law and is essential for initiating and maintaining the transmission of light signals through the fiber.

Fiber optic cables are designed with a core (high refractive index) surrounded by a cladding (lower refractive index).

When light enters the core at a suitable angle, it refracts and then reflects entirely within the core due to total internal reflection. This process allows light to travel long distances with minimal loss, even around bends and curves in the cable.

Refraction is thus the key mechanism that enables high-speed, high-bandwidth communication in applications such as internet infrastructure, medical imaging, and data centers. Without refraction and the resulting internal reflection, fiber optics would not be able to confine and direct light efficiently.
