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 Has More Capacity
This single fiber can carry more communications than the giant copper cable!

Fiber Optic Communications
• Applications include – Telephones– Internet– LANs - local area networks– CATV - for video, voice and Internet connections– Utilities - management of power grid– Security - closed-circuit TV and intrusion sensors– Military - everywhere!

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

Presented By The Fiber Optic Association©2004, The Fiber Optic Association, Inc.
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.
