What Is Fiber Optics ?

Transmittingcommunicationssignals over hair thinstrands 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 distancecommunications While we already transmit signals at Gigabits

per second speeds, we have only started toutilize the potential bandwidth of fiber
