Specialty optical fibers and glass polarizers for telecommunications, sensing, industrial, and medical industries.

Changing the Way You See and Use Fiber

Corning’s Specialty Fibers are used in a wide range of applications including fibers required for components in the well-established telecommunications market to the fibers required in emerging markets like medical, lighting and sensing applications and beyond. We can design custom fibers to support entirely new markets and innovations where fibers will be an essential component.

Our strategy is to look at fiber — the actual glass core and cladding, and the protective coatings — in terms of a matrix where each or all can be rapidly customized at our customers direction. We can do this in terms of size, optical properties, temperature/environment resistance, bend insensitivity, operating wavelength, etc.

If you don’t see a particular fiber in our catalog that meets your needs, please contact us to discuss your unique requirements.

Our specialty fibers serve the following markets: aerospace and defense, geophysical, harsh environment, medical, sensing and lighting.

What We Do

Corning specialty optical fiber offers a large portfolio of products, and more importantly an even larger set of capabilities. Being a specialty house, we understand that our customers might need one meter of highly engineered fiber or one-thousand kilometers of the world’s most consistent erbium fiber for EDFA.

To do this we use our multiple, flexible development and manufacturing platforms (patented OVD), our deep knowledge of material science, and leveraged supply chain of the world’s largest fiber company.Learn More

Sensing: Know-How for Quick Response

More often optical fibers are used for communications as well as sensing elements in a wide variety of growing applications. Optical fiber has inherent advantages over other types of sensors given they are immune to EMI, have a wide temperature range usage, and can be multiplexed. We understand that what makes an ideal fiber for communications, might not be ideal as a sensing fiber. So we develop and manufacture fibers with unique properties to match the application. We have the deep knowledge and capabilities to rapidly customize the glass and/or coatings of the fiber to optimize performance to fit our customer’s required needs.

Lighting: Unleash the Glow

We have been in lighting since producing the first glass lightbulbs in 1879 for Thomas Edison. Now we have invented a new lighting product called Corning® Fibrance™ Light-Diffusing Fiber, a glass optical fiber optimized for thin, colorful aesthetic lighting. Unleash the brilliant design possibilities with this emerging lighting technology. Its unique attributes make it relevant for numerous applications. It is offered as a single strand of fiber or a bundle.
