Transmitting communications signals over hair thin strands of glass or plastic

Not a "new" technology

Concept a century old Used commercially

since 1980

Fiber is the least expensive, most reliable method for high speed and long distance communications

Fiber is the least expensive, most reliable method for high speed and/or long distance communications

While we already transmit signals at 100 Gigabits per second speeds, we have only started to utilize the potential bandwidth of fiber

Outside Plant vs Premises Installations

A glass optical fiber is about twicethe size of a human hair.

Fiber uses reflection (L) to contain light inside the coreof the fiber (below).

CoreCladding

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

Protects the fibers wherever they are installed

May have 1 to >1000 fibers

Terminates the fibers Connects to other fibers or transmission

equipment

Designing components Manufacturing fiber, lasers, etc. Designing systems Installing networks Training and teaching
