What is Fiber Optics?

Fiber Optics is the communications medium that works by sending optical signals down hair-thin strands of extremely pure glass or plastic fiber.

The light is “guided” down the center of the fiber called the “core”.

The core is surrounded by a optical material called the “cladding” that traps the light in the core using an optical technique called “total internal reflection.”

The fiber itself is coated by a “buffer” as it is made to protect the fiber from moisture and physical damage.

The power of fiber optic communications connects the world.

The red lines are all the submarine fiber optic cables that connect the places where people live and provide their communications links to each other.

Fiber optics connects the world under the seas and over the land. Virtually all communications at some point travels via fiber optic cable.
