At Corning, innovation never stops. We changed communications when we invented low-loss optical fibre.

Fibre Basics


The History of Fibre

For years we have operated within a culture of innovation that has positioned us as the world leader in specialty glass and ceramics. In 1970, we ignited the communications revolution by inventing the first low-loss optical fibre for use in telecommunications networks around the world. Since fibre was invented over 40 years ago, our ongoing product and process invations have helped make possible ever-faster telecommunications networks that link neighborhoods, connect cities and bridge continents.

The Modes of Light

How It Works

Brilliant clarity over distance.

Known for innovative design and practical applications, we have developed an array of single-mode fibre and multimode fibre products for all of today's applications. Single-mode fibre has a smaller core, allowing only one mode of light to move through it at a time. This streamlined design is used primarily in telephony applications, where the fibre needs high signal clarity over long distances. Multimode fibre has a larger core, allowing hundreds of modes to move through the fibre simultaneously. Multimode fibre is used primarily for data communications in enterprise networks, like campuses or buildings where transmission distances are two kilometers or less.
