It is a cabling technology that uses optical fibers to carry digital data signals in the form of modulated pulses of light. The core of fiber-optic cable is made of glass or plastic and the cladding that are enclosed by a protective coating. Outer insulating jacket is made of Teflon or PVC. Kevlar fibers are used to strengthen the cable and prevent from breakages.
A brief overview of the advantages of fiber-optic cable over coaxial and twisted pair:
Speed: Fiber optic networks operate at high speeds in the gigabits range.
Bandwidth: High-capacity data transmission.
Distance: Due to lack of attenuation Signals can be transmitted over long distances without using repeaters.
Resistance: Greater resistance to outside interferences such as radios, motors and electromagnetic noise.
Expensive and very fragile.
