Key Points
- Light is faster then electrical signal propogation
- No electromagnetic interference
- No attenuation
- System source-fiber-detector
- Fiber (light wire) works by total internal reflection
- Modes are present and cause dispersion
Questions
- Why use light for information transfer?
- How does a optical fiber work
- What is a mode in a fiber
- Why do fibers cause dispersion - how could we control
it.
