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

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
