Fibre optic is a technology that allows light to be guided through a cable, providing illumination, data transmission and other functions. It is among the most efficient ways to transmit data in the world, allowing data to be transmitted over very long distances at significant bandwidths.
Fibre optic has largely displaced many other technologies used for data transmission and, in fact, many people get their Internet connections in their homes delivered via fibre-optic technology.
Fibre-optic technology has become so ubiquitous that inexpensive fibre-optic products are readily available, such as lighting devices that allow light to be directed in hard to reach places where providing illumination by means of a flashlight or another device could be excessively difficult.
Fibre-optic technology has many characteristics that make it particularly suited for the modern world. It has properties that make it usable under conditions where other forms of data transmission are subject to significant interference or other issues that may compromise the quality of the data or slow down communication. Fibre-optic cables, for instance, can be manufactured so that they are suitable for use underwater, which makes them ideal vehicles for transmitting data across continents for large-scale networks, such as the Internet.
Fibre-optic technology is significantly important to technology on the whole in the modern world. Without it, slower data rates would compromise the ability of the Internet to get information around the world as quickly as it does and as reliably as it does.
