Corning® ClearCurve® Single-Mode Optical Fiber Exceeds the New ITU-T Recommendation G.657.B.3 Standard
Corning, NY, October 28, 2009 – Today Corning Incorporated (NYSE: GLW) announced its ClearCurve® bend-insensitive, single-mode optical fiber is fully compliant and exceeds the new ITU-T G.657.B.3 recommendation and the existing ITU-T G.652.D recommendation. Corning ClearCurve single-mode fiber is the world's first optical fiber specified for macrobend at a 5-millimeter radius that is fully compatible with existing telecommunications networks.
On Oct. 9, the ITU-T Study Group 15 on optical transport networks and optical access networks approved adding the 5-millimeter radius macrobend specifications into the existing ITU-T G.657 recommendation, the industry standard that outlines the macrobend performance for optical fiber. Reflective of recent industry trends, the revised recommendation now accounts for three distinct levels of macrobend performance: 5-,
7.5-, and 10-millimeter radii. Now, end users can easily specify different levels of bend performance based on their application needs.

"We value the collaborative work of industry standards organizations and believe adding 5-millimeter better defines the realities of access networks and the needs of our customers,” said Martin J. Curran, senior vice president and general manager, Corning Optical Fiber. “With Corning ClearCurve single-mode fiber, our customers can maintain the benefits of single-mode optical fiber while decreasing deployment time, maximizing system reliability, minimizing downtime, and realizing overall space savings and reduced cost."
In addition to ClearCurve single-mode fiber, Corning has a full portfolio of single-mode fiber that exceeds each of the newly defined ITU-T G.657.A.1, G.657.A.2, G.657.B.2, and G.657.B.3 recommendations. Corning’s full portfolio of bend-improved fibers allow designers, installers, and operators of telecommunications access networks and equipment to deploy optical fiber cables in more places by delivering all of the bandwidth benefits of optical fiber in a package that is as easy to handle and install as copper communication cables.
In 2007, Corning introduced its award-winning ClearCurve single-mode fiber which solved the technical and physical challenges faced by telecommunications carriers installing FTTH networks, particularly in multi-dwelling units. Bend improved fibers, including ClearCurve single-mode and multimode fibers, are the latest optical fiber innovations from Corning. Corning invented the first low-loss optical fiber nearly 40 years ago and, since then, Corning has revolutionized telecommunications by developing fiber innovations such as the first dispersion-shifted fibers, large effective area fibers, and ultra-low-loss fiber for long-haul and high-data rate transmission; the first laser-optimized multimode fibers for enterprise networks; and the first G.652.D compatible SBS-enhanced fibers and bend-insensitive single-mode fibers for access and broadband applications.
