Optical fiber is used to transmit data as light signals over long distances. It's commonly used in:
The key advantage of optical fibers is that they allow for faster, more reliable data transmission over greater distances than other methods, such as copper cables.
- Telecommunications: Optical fibers are the backbone of phone and internet networks. They allow for faster data transmission with less signal loss compared to traditional copper wires.
- Internet and TV: Fiber-optic cables deliver high-speed internet and television services because they can carry large amounts of data at faster speeds.
- Medical Field: Optical fibers are used in medical instruments like endoscopes. These are thin tubes that doctors use to look inside the body without making large incisions.
- Networking: Optical fibers are also used in computer networks to connect devices at high speeds, often in data centers.
- Military and Aerospace: They are used for secure communication systems due to their resistance to interference and ability to cover long distances.
- Sensors: Optical fibers can also be used in sensors to monitor things like temperature, pressure, and strain, especially in harsh environments.
