How does Fiber Optic Internet Work? Garth Naar
ď ˝
Fiber internet is popular for businesses looking to boost productivity. We’ll explain how these tiny glass tubes of light can transfer anything from emails with cute cat GIFs to high-definition videos anywhere around the world.
Core ď ˝
The first and most important layer is the core. The core is made up of thousands of glass tubes bundled together and supported by a central strength element (e.g. a metal rod).
Cladding ď ˝
The second layer of a fiber optic cable is the protective sheath called cladding. This increases the core’s total internal reflection to prevent data loss.
Plastic Coating ď ˝
Plastic coating is wrapped around the fiber optic cable to reinforce the core and cladding for the third layer.
Strengthening Fibers ď ˝
The fourth layer of the cable is made of strengthening fibers for added support.
Cable Jacket ď ˝
Finally, the layers are wrapped in a cable jacket to protect against elements. This outer layer is found on every cable and wire.
