Fiber Optic Cable
Light created by an LED (light-emitting diode) or laser is sent down a thin glass or plastic fiber
Has extremely high capacity, ideal for broadband
Works better under harsh environments
- Not fragile, nor brittle; Nit heavy nor bulky
- More resistant to corrosion, fire, etc.,
Fiber optic cable structure (from center):
- Core (v. small, 5-50 microns, ~ the size of a single hair)
- Cladding, which reflects the signal
- Protective outer jacket
