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
History of Fiber Optics
Total Internal reflection is the basic idea of fiber optic
John Tyndall demonstration in 1870

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!
Presented By The Fiber Optic Association©2004, The Fiber Optic Association, Inc.
Why Use Fiber Optics?
• Economics• Speed• Distance• Weight/size• Freedom from interference• Electrical isolation• Security
Presented By The Fiber Optic Association©2004, The Fiber Optic Association, Inc.
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.

Wavelength-Division Multiplexing
Presented By The Fiber Optic Association©2004, The Fiber Optic Association, Inc.
Fiber Optic Cable
• Protects the fibers wherever they are installed
• May have 1 to over 1000 fibers
Presented By The Fiber Optic Association©2004, The Fiber Optic Association, Inc.
Fiber Optic Connectors
• Terminates the fibers• Connects to other fibers or transmission
equipment
