Fiber optic

Definition

Fiber optic refers to the technology that uses thin strands of glass or plastic fibers to transmit data as light signals over long distances. This method of data transmission allows for higher bandwidth and faster speeds compared to traditional copper wires, making it essential in modern network architecture and protocols.

5 Must Know Facts For Your Next Test

1. Fiber optic cables are made up of a core surrounded by cladding, which reflects light back into the core, allowing signals to travel long distances with minimal loss.
2. The use of fiber optics can significantly reduce interference compared to electrical signals in copper wires, resulting in clearer and more reliable data transmission.
3. Fiber optic networks can support high-speed internet services and are crucial for backbone infrastructure in telecommunications and data centers.
4. There are two main types of fiber optic cables: single-mode fibers for long-distance communication and multi-mode fibers for shorter distances within buildings or campuses.
5. Installing fiber optic technology can be more expensive than traditional wiring but offers long-term savings due to lower maintenance costs and increased efficiency.

Review Questions
