What Is Fiber Optics ?
Transmitting communications signals over hair thin strands of glass or plastic
Not a "new" technology
Concept a century old
Used commercially for last 25 years

Fiber Optic Applications
Fiber is already used in:
> 90% of all long distance telephony
> 50% of all local telephony
Most CATV networks
Most LAN (computer network) backbones
Many video surveillance links

Fiber Optic Applications

Fiber is the least expensive, most reliable method for high speed and/or long distance communications
While we already transmit signals at Gigabits per second speeds, we have only started to utilize the potential bandwidth of fiber

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