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
