What Is A Fiber-Optic Cable?

fradminCommon Internet FAQs

A fiber-optic cable holds multiple strands of fiber in order to transfer data. Each fiber is made of flexible glass or plastic and transmits light signals. This technology provides homes and businesses with phone, Internet and TV services. Because fiber-optic cables use light, they can transmit more data, farther and in less time than other mediums.

What makes up a fiber-optic cable?

A fiber is made up of a core, a cladding and a plastic buffer. The core, like the name implies, is at the very center of the fiber. This is made from very thin plastic or glass. Surrounding the core is the cladding, where the light is reflected into. This is made of an optical material. The plastic buffer then surrounds both the core and the cladding to protect the materials from any damage.

Once multiple fibers are put together and covered, they create a fiber-optic cable. The cables deliver the signal to a “node,” which is a type of network box. From the node, the signal can travel to one of two places – to a curb within 1,000 feet of a home or business, or directly to a building or house.

How does fiber optic work?

Laser-generated pulses of light are transmitted by fiber-optic phone lines and cables to provide phone, Internet and TV services to homes and businesses. The data is converted from light to electricity so it can be understood on the receiving end.

Multimode vs. single-mode fibers

There are two main types of fiber-optic cables. A multimode fiber uses multiple light sources to transmit several data streams. Because of its small core, a single-mode fiber can carry more bandwidth over a long distance. However, it only allows one data stream to travel.

Faster speeds and greater reliability

Fiber-optic cables provide the best entertainment and communications services. Through this technology, homes and businesses can enjoy faster speeds and greater reliability. The availability is limited; however, many Internet service providers are expanding their fiber-optic networks.
