Fiber optic

Definition

Fiber optic refers to a technology that uses thin strands of glass or plastic fibers to transmit data as light signals over long distances. This method of data transmission enables high-speed internet connections and is crucial for modern communication infrastructure, offering advantages like increased bandwidth and reduced signal loss compared to traditional copper wires.

5 Must Know Facts For Your Next Test

1. Fiber optic cables can carry large amounts of data over long distances without significant loss of quality, making them ideal for internet backbone connections.
2. They are immune to electromagnetic interference, which makes them more reliable than traditional copper cables in environments with high electrical noise.
3. The speed of data transmission in fiber optics can reach up to 99.7% the speed of light, significantly faster than copper wire connections.
4. Fiber optic technology is not only used for internet connections but also for telecommunications, medical instruments, and lighting applications.
5. There are two main types of fiber optic cables: single-mode fibers, which are used for long-distance communication, and multi-mode fibers, which are more suitable for shorter distances.
