Optical Fibre Myths

Optical Fibre Myths

Whether we’re filling a glass of water or washing our windshield, we take glass for granted as a functional yet fragile part of our everyday lives. Discover the myths and the facts behind optical fiber.

Myth #1 - All glass is the same

After a century and a half of glass research, we hold thousands of patents for glass technology. A single element added to glass can significantly change its properties. By adding titanium-doped silica to glass rods for example, Drs. Robert Maurer, Peter Schultz, and Donald Keck invented low-loss optical fibre, a technology that has revolutionised the way in which we connect and communicate around the world.

Myth #2 - Glass carries only solids or liquids

When we think of using glass containers, we usually picture filling a cup or opening a jar. But with the invention of low-loss optical fibre, we use hair-thin strands of glass to carry data, voice, and video by containing and transporting light signals. Comprised of a light transmission area (or core), and wrapped in a light-wave containment material called cladding, each optical fibre acts as an information highway, offering nearly limitless capacity to our bandwidth-hungry world.

Myth #3 - Glass is fragile

Who hasn’t dropped a glass, only to see it shatter across the kitchen floor? Yes, glass used in everyday consumer products can be fragile. But by changing the properties of glass at the molecular level, Corning scientists continue to make glass products that are as strong as steel. As thin as a strand of human hair, every centimetre of optical fibre is proof-tested through a rigorous manufacturing process for tensile strength at a minimum of 100,000 pounds per square inch. Far from being fragile, optical fibre is durable enough to withstand handling during installation and deployment in harsh environmental conditions in networks all around the world.

Myth #4 - Glass is for windows

We see the world through the glass in our windows; we connect with the world through the glass within optical fibre. Since its invention over 40 years ago, more than 2 billion kilometers of fibre have been installed around the world, creating an information superhighway that instantly and continuously connects us to global communications networks through devices such as computers, smart phones, high definition televisions, game systems, e-readers, and more.

Myth #5 - Glass doesn’t bend

While the glass we use every day seems inflexible, optical fibre is flexible enough to bend to a radius as small as 5mm, thanks to our invention of ClearCurve® single-mode optical fibres. Manufactured for much more challenging installations and environments, these fibres bend around tight corners and can be used in hard to reach places without sacrificing performance. Time magazine named this product as one of the best inventions of 2007.

Myth #6 - Glass is low tech

Corning’s low-loss optical fibre ignited the Information Age and continues to serve as the “high tech” backbone that supports the Internet, wireless and countless interactive technologies that we depend on every day. Over the past four decades, we have built on this groundbreaking invention by continuing to develop new fibre technologies for submarine, long-haul, fibre-to-the-home, and enterprise networks that enable faster, better, and more cost-effective communication.

Myth #7 - Glass can’t change the world

Through optical fibre, it already has. What began as a breakthrough discovery in 1970 has become a technology that has revolutionised the way in which we connect, communicate, and conduct business. By reading this Web page on the Internet, you are part of that revolution, joining the billions of other people accessing data, voice, and video nearly instantaneously, via optical fibre. Thanks to the power and pervasiveness of optical fibre, we are a world that runs literally at the speed of light.
