Every once in a great while a technological

breakthrough comes along that changes the

world. Today that technology the union o

glass and light is optical ber.

Necessity Is the Mother of Invention

Responding to consumer demand or bandwidth beyond what traditional cables could provide,three Corning scientists Dr. Robert Maurer, Dr. Peter Schultz, and Dr. Donald Keck invented therst commercially viable low-loss optical ber in 1970. Their revolutionary discovery provided theworld with a rapid, reliable telecommunications medium with low signal loss over long distancesand virtually limitless bandwidth.

In its basic orm, an optical ber is a hair-thin, highly transparent strand o glass comprised othree parts:

(1) the core that carries inormation in the orm o light signals;(2) the cladding which surrounds the core trapping the light within it; and(3) the durable, protective outer coating. Encoded into light signals, inormation

travels through the ber where it is decoded locally or thousands o miles away.

The Future Is Here

When discovered, optical ber promised a uture o unlimited possibilities, but only i it could bemass-produced and widely accessible. Thanks to Corning, it is. Cornings proprietary manuactur-ing processes continue to set the industry standard or the deployment o low-cost, high-capacity

optical ber communications systems. Today, with more than 1.5 billion kilometers o optical berinstalled around the globe, we are a world dependent upon the speed-o-light transmission oinormation to virtually anyone, anywhere at anytime. In other words, the uture is here.

Connecting At the Speed of Light

Cornings product innovations continue to bring optical ber closer to our homes and hands,transorming the ways we live, work and play and enabling service providers to deliver seamless,instant, and continuous connections to the Internet and other communications networks. Thisaccess has dramatically increased our entertainment options HDTV, e-books, online shopping,and game systems; opportunities or social interaction, chat rooms, blogs; and job fexibility remote e-mail access, teleconerencing, wireless laptops, and telecommuting. None o this evenwireless would be possible without the consistent reliability, ongoing durability, and limitlessbandwidth oered through optical ber.

Likewise, educational institutions, healthcare acilities, and businesses are relying on optical beror their Data Centers and Local Area Networks (LANs). Fiber directly to the desk enables users tocommunicate over longer distances and reserve higher bandwidth or uture expansion. Fromonline courses to remote patient monitoring to international teleconerencing, optical bercontinues to increase productivity and protability or organizations by streamlining the ways inwhich they provide services around the world.

Fiber: The Clear Choice

Quality Transmission

Unlike copper cabling, optical ber is immune to electrical noise (Electromagnetic Intererence or EMI).

When were rustrated by static on our phones or televisions, bers reliable signal is a welcome conve-nience. But within industrial and military environments, clear data transmission is a vital necessity. Indus-

tries with loud production lines and heavy machinery have turned to ber optics or their internal commu

nications. Similarly, the United States military uses ber to support time-critical communications because

its signal is dicult to damage, tap, or jam.

Cost-effectiveness

As o 2010, submarine cables now link all o the worlds continents except Antarctica. Copper networks

need multiple ampliers and repeaters to boost light signals and prevent signal loss. This additional equip

ment increases network cost over long distances. Cornings new ultra-low-loss, large-eective-area sub-

marine optical ber, Vascade EX2000, however, is designed or signal transmission over hundreds o mile

beore it needs to be amplied or regenerated, making it a cost-eective alternative to copper wire.

Rugged Durability

Optical ber may be made o glass, but inch or inch its stronger than steel and more durable than coppe

At Cornings Center or Fiber Optic Testing acility, we set the industry standard or perormance testing.

Every centimeter o optical ber is strength tested at a minimum o 100,000 pounds per square inch to

ensure its mechanical robustness.

There is no theoretical lietime or optical ber. The ber optic cables manuactured and installed 40

years ago are still in use today, and we know our newest cables are even stronger. Our Outside Plant (OSP)

cables, or example, are designed to withstand environmental extremes. They oer clear signal peror-

mance over a wide range o temperatures while resisting water ingress and years o the suns ultraviolet

radiation. And by carrying light instead o electricity, OSP cables are sae rom lightning strikes or electrica

aults. Fiber is the clearest choice today, and its rugged durability is showing us that we have every reason

to believe well be relying upon it or many years to come.

Scalability

Traditional copper cabling constantly struggles to meet growing bandwidth needs. As data trac on

wireless networks continues to explode (90,000 terabytes o trac per month today is expected to hit

3,600,000 terabytes per month by 2014), optical bers scalability makes it the clear choice or whats now

and whats next.

Joining the Global Conversation

Once considered a personal convenience, being connected has now become an interna-tional priority. In todays world, optical ber is the core o connectivity, providing the mediumthrough which commerce and culture are being simultaneously created and communicated

on a personal and global scale.

Corning led and continues to lead the development and delivery o the latest generation ooptical ber, making it practical or new applications and possible or burgeoning markets. Asglobal telecommunications networks expand and evolve, Corning will lead the way orward inconnecting each and every one o us at light speed, one strand o ber at a time.

Fiber Is FastOptical ber can transmit 15.5 terabits o data per second over a distance o 7,000 kilometers. Trans-lation? It would take approximately 25 seconds to send the entire iTunes catalogue rom the sunny

beaches o Florida to the bustling streets o London .

Fiber Bends

While the glass we use every day seems infexible, Cornings revolutionary ClearCurve single-mode and multimode optical ber is fexible enough to bend around tight corners, twist into hardto reach places and loop within smaller terminal boxes without sacricing perormance.

Fiber Is Light And Easy To HandleAn optical ber is only 250 m diameter -- the size o a human hair. Fiber optic cables are

orders o magnitude smaller and more fexible than the CAT5 copper cables that provide a ractiono the bandwidth.

Fibers Capacity Blows Copper AwayWhen it comes to bandwidth, ber is king. A single ber is capable o transmitting 250 million

phone conversations every second. One mile o ber weighs about 1/4th o a pound whereas cop-per cable with the same inormation-carrying capacity would weigh 33 tons.

Fiber Brings Us TogetherNearly two billion people are instantaneously and simultaneously accessing the Internet, thanks

to optical ber. Were able to exchange inormation, conduct business, learn, share, be entertained,and stay connected with amily and riends almost anywhere, almost anytime.

Fiber Means BusinessA one millisecond advantage in trading applications can be worth $100 million a year to a major

brokerage rm. (Inormation Week April 2007)

Fiber Is GreenUnlike traditional copper wiring, optical ber doesnt generate excess heat while operating, reduc-ing the load on power-hungry data center cooling systems. Businesses interested in internationallyrecognized Leadership in Energy and Environmental Design (LEED) certication are choosing optical

ber cabling systems to create more cost-ecient, environmentally riendly data centers.

Fiber Is More SecureUnlike copper wires, it is very dicult to tap or bug optical ber. An attempt to tap into a ber

cable can cause the glass to break, likely triggering maintenance and/or surveillance alarms. Thelow power levels used or optical signals increases the system sensitivity to any invasive power loss.

Fiber Is Cost-Effective

Traditional copper cable requires repeaters to ampliy signals every mile, whereas optical bersystems need repeaters every sixty miles or more. This cost advantage was one o the key drivers in

the installation o undersea cables that now connect every continent except Antarctica.

Fiber Keeps Getting Better

The rst viable low-loss ber invented by Corning in 1970 had an attenuation o 17 db/kilometer. To-day, Cornings SMF-28 ULL ber is 100 times better with signal loss o just 0.17 db/kilometer. And,

were working to ensure that the next generation bers are better still.
