SMF-28 Ultra Optical Fiber

SMF-28® Ultra optical fiber was the first in the market to combine the benefit of industry-leading attenuation and improved macrobend performance, all in one fiber. This premium single-mode fiber is designed for regional, long-haul, metro, access, mobile, and fiber to the home (FTTH) applications, along with being fully backward compatible with the installed base of legacy single-mode fibers.

With the benefit of mode field diameter (MFD) backward compatibility, network operators have the freedom to deploy fiber-rich, high-density cables to address capacity and congestion – with the proven performance of SMF-28 Ultra fiber.

SMF-28 Ultra fiber can be purchased natural, colored, or ringmarked. Corning fibers with ColorPro® identification technology, our coloring solution, enable cable manufacturers to reduce cost, minimize footprint, and leverage an enhanced product offering. Find more information about Corning ColorPro Identification Technology.

SMF-28 Ultra 200 Optical Fiber

In 2015, we introduced the industry’s first 200-micron fiber which provides low loss, macrobend performance, and a 9.2-micron MFD. SMF-28 Ultra 200 fiber helps solve one of the world’s toughest network challenges – increasing fiber count without taking up more space – by providing all the benefits of SMF-28 Ultra fiber in a reduced diameter.

The newest addition to our SMF-28 Ultra fiber portfolio, SMF-28 Ultra 200 fiber, enables the design of smaller, lighter high-fiber-count, high-density cables. By exceeding the standards requirements of ITU-T G.657.A1 and G.652.D, SMF-28 Ultra 200 fiber ensures full backward compatibility with other fiber types that satisfy these requirements.

SMF-28 Ultra 200 fiber can be purchased natural, colored, or ringmarked. Corning fibers with ColorPro identification technology, our coloring solution, enable cable manufacturers to reduce cost, minimize footprint, and leverage an enhanced product offering. Find more information about Corning ColorPro Identification Technology.
