Study Notes
- Fiber optics is a type of network communication using light instead of electrical signals.
- It allows for long-distance communication without signal degradation and is immune to radio frequency interference.
- Fiber optic connectors are large with a protective cover, enclosing a small and thin fiber inside.
- Light is sent through the fiber using an LED or laser and reflects in the highly reflective core, bouncing until it reaches the other end.
- Two types of fiber optic cables exist: multimode and single-mode. Multimode fiber is for short-range communication using an inexpensive LED and has a larger core allowing multiple modes of light. Single-mode fiber has a smaller core, allowing only one mode of light and uses a laser for long-distance communication.
- Multimode fiber is suitable for short-range communication (up to 2 kilometers) and single-mode fiber for long-distance communication (up to 100 kilometers).
- Single-mode fiber is more expensive due to the requirement of a stronger laser light source.
