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!

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
