Optical Fibre - English Definition & Meaning

Definition

Optical fibre, also spelled "optical fiber," is a thin, flexible strand of glass or plastic that transmits light signals. It's like a microscopic, super-efficient light pipe. This technology allows for very fast data transmission over long distances. Think of it as the superhighway for the internet, sending information at the speed of light. Unlike copper wires, it's immune to electromagnetic interference and can carry more data. It is a key component of modern communication networks.

Etymology

"Optical" comes from the Greek "optikos," relating to sight or vision, since light is used to transmit data. "Fibre" (British spelling) comes from the Latin "fibra," meaning a thread or filament. Together, it means a thread that uses light. Development ramped up in the 20th century, revolutionizing communication technology. The etymology emphasizes its reliance on light for data transfer.
