Fiber-optic cables—"pipes" can carry telephone calls and emails right around the world using the speed of light! Fiber optic means sending light beams down thin strands of glass. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed.
Different types of fiber, such as multi-mode and single-mode are used for different applications. For example, long distance telecommunication, or providing a high-speed data connection between different parts of a building; the bandwidth surpasses the needs of today’s applications and gives room for growth tomorrow!
