Fiber Optics: The Future Of The Internet
Outline
• Fiber Optics What is it?
• Research Questions
• History
• What it does today
• Types of Cables
• The Future
Fiber Optics What Is It?
• Fiber Optics are cables that are made of optical fibers that can transmit large amounts of information at the speed of light. (www.dictionary.com)
Research Questions
• What can fiber optics do for us in the future?– Improve our communication– Faster internet connection
• What would the Internet look like if this could happen?– Streaming capabilities– Download capabilities
• What is being done to make this transition happen?– Government action– Private Companies at work
Research Resources
• Internet
• Library
• Magazines (IEEE)
History• 1961-“Industry researchers Elias Snitzer and Will
Hicks demonstrate a laser beam directed through a thin glass fiber. The fiber’s core is small enough that the light follows a single path, but most scientists still consider fibers unsuitable for communications because of the high loss of light across long distances.” (www.greatachievements.com.)
• 1970- Researchers find a way to super purify glass fibers.
• 1980- At&t installs first set of fiber optic cables in major cities.
History
• 1988- First transatlantic cable
• 1996- First transpacific cable
• 1997- First Fiber Optic Link Around the Globe (FLAG)
Present
• Telecommunications
• Internet Access
• Cable and Satellite Television
• Decorative Light Source
The Cable
• Fiber Optic have three major characteristics– Composed of fibers either glass or plastic
and sometimes both
– Are very flexible
– Have different tips
Components
• Outside Jacket
• Cladding
• Core
Glass Fibers
Characteristics
• Glass Core
• Glass Cladding
• Ultra Pure Ultra Transparent Glass
• Made Of Silicon Dioxide
• Low Attenuation
• Popular among industries
Plastic Fibers
Characteristics
•Core Generally Consists Of Polymethyl Methacrylate (Acrylic Glass) (PMMA) Coated With A Fluoropolymer
•High Attenuation
•Used Mostly In Automotives
•Affordable
•Very Durable
Plastic Clad-Silica(PCS)
• Glass Fiber Core sometimes silicone
• Cladding is Plastic or silicone
• Silicone covering and insulators
• Not common
• Has Defects
Government Involvement
• United States Itself has fallen behind Europe
• Pace of fiber optic expansion has started to speed up again
• Research for having more soldiers at home base fighting using a robot
Private Companies Input
• Several Private Companies have offered large scale fiber optic networks
• Underground networks are already in place and are being used by secret societies
• UCSB itself has eight rings of fiber optic networks on campus
The Future
The Internet
• Bandwidths of up to 10Gbps
• Streaming Whole Movies in HD
• Effortless video conferencing with no lagging
• Gaming in HD quality that never lags
