Corning® ClearCurve® ZBL Optical Fiber Product Information Bend Performance and Compatibility Corning® ClearCurve® ZBL Optical Fiber delivers the best macrobending 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. ClearCurve fiber 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-28e® and 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.

Optical Specifications Maximum Attenuation Maximum Value* Cable Cutoff Wavelength {XJ Mode-Field Diameter *Maximum specified attenuation value available within the stated ranges. ** Attenuation values at this wavelength represent post- hydrogen aging performance. Alternate attenuation offerings available upon request. Dispersion Value The attenuation in a given wavelength range does not exceed the attenuation of the reference wavelength (X) by more than the value a. Zero Dispersion Wavelength (X0): 1304 nm < X0 < 1324 nm Zero Dispersion Slope (S0): < 0.092 ps/(nm2-km) Polarization Mode Dispersion (PMD) Value (ps/Vkm) PMD Link Design Value Maximum Individual Fiber PMD Macrobend Loss Mandrel Number Wavelength Induced *The induced attenuation due to fiber wrapped around a mandrel of a specified diameter. Point Discontinuity ♦Complies with IEC 60794-3: 2001, Section 5.5, The link design value is a term used to describe the PMD of concatenated lengths of fiber (also known as PMDQ). This value represents a statistical upper limit for total link PMD. Individual PMD values may change when fiber is cabled. Coming's fiber specification supports emerging network design requirements for high-data-rate systems operating at 10 Gb/s or higher. Point Discontinuity protected with
