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.
