Higher capacity Transmit signals at 100
Gigabits per second speeds
Travel much longer distances down a fiber cable without losing its strength
Less susceptible to interference

Fiber uses reflection (L) to contain
light inside the core of the fiber
(below).
Total internal reflection (refractive
index should be n2 > n1),
Lange Law

Core Cladding Coating Strengthening fibers Cable jacket
Standard Telecommunications core diameter:
For SMF is between 8 m and 10 m,
For MMF is between 50 m and 62.5 m.
Diameter of the cladding is 125 m

Three types of material make up
fiber-optic cables:
Glass Fiber-Optic Cable
Plastic Fiber-Optic Cable

Fiber optic systems transmit using
infrared light
invisible to the human eye
It goes further in the optical fiber at those wavelengths.
