Corning ClearCurve ZBL Single Mode Fiber (G.657 A/B)
Bend Performance and Compatibility
Corning ClearCurve ZBL Optical Fiber delivers the best macro bending performance in the industry while maintaining compatibility with current optical fibers, equipment, practices and procedures.
This full-spectrum single-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, while remaining 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 challenging installations and environments, and cable designers can offer optical cables with unmatched ruggedness for easier installation and handling.
