Corning ClearCurve fiber exceeds new ITU-T Recommendation G.657.B.3
OCTOBER 28, 2009 -- Corning says its ClearCurve singlemode fiber is the first optical fiber specified for macrobend at a 5-mm radius that is fully compatible with existing telecom networks.
OCTOBER 28, 2009 -- Corning Incorporated has announced its ClearCurve bend-insensitive, singlemode 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 says its ClearCurve singlemode fiber is the first optical fiber specified for macrobend at a 5-mm radius that is fully compatible with existing telecom networks.
On Oct. 9, the ITU-T Study Group 15 on optical transport networks and optical access networks approved adding the 5-mm 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-mm radii. End users can easily specify different levels of bend performance based on their application needs.
|10 mm||7.5 mm||5 mm|
|G.652 not required||G.657.B.2||G.657.B.3|
"We value the collaborative work of industry standards organizations and believe adding 5 mm better defines the realities of access networks and the needs of our customers," explains Martin J. Curran, senior vice president and general manager, Corning Optical Fiber. "With Corning ClearCurve singlemode fiber, our customers can maintain the benefits of singlemode optical fiber while decreasing deployment time, maximizing system reliability, minimizing downtime, and realizing overall space savings and reduced cost."
In addition to ClearCurve singlemode fiber, Corning has a full lineup of singlemode 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.
