Corning ClearCurve ZBL Single Mode Fiber (G.657 A/B)
Bend Performance and Compatibility
Corning ClearCurve ZBL Optical Fiber delivers the best macrobending performance in the industry whilemaintaining compatibility with current optical fibers, equipment, practices and procedures.
This full-spectrµmsingle-mode optical fiber when subjected to smaller radii bends experiences virtually no signal loss. ClearCurvefiber exceeds the most stringent bend performance requirements of ITU-T Recommendations G.657.B3, whileremaining fully compliant with ITU-T Recommendation G.652.D and the installed base of Corning SMF-28eand SMF-28e+ fiber.
Now network planners and designers can design optical fiber into much more challenginginstallations and environments, and cable designers can offer optical cables with unmatched ruggedness foreasier installation and handling.
