Yes, optical fiber can be considered a type of transmission line, but it’s a specific kind designed to transmit light signals rather than electrical signals.
Just like traditional electrical transmission lines (like coaxial cables or waveguides), optical fibers are used to carry information over long distances. The main difference is that optical fibers use light waves (usually in the infrared spectrum) to carry the signal, whereas electrical transmission lines carry electrical signals (like voltage or current).
An optical fiber consists of a core (made from glass or plastic) through which light travels, and a cladding around the core that keeps the light signals from escaping. The fiber’s structure ensures that the light signals remain inside the core, bouncing off the cladding in a way that helps maintain signal integrity over long distances.
So, while the technology is different, both optical fibers and traditional transmission lines serve the same basic purpose: to transmit signals from one point to another.
