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 ba 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.

* M aximum specified attenuation value available within the stated ranges.
** A ttenuation values at this wavelength reprent post-hydrogen aging performance.
Alternate attenuation offerings available upon request.
The attenuation in a given wavelength range does not exceed the attenuation of the reference wavelength (λ) by more than the value of α.
* T he induced attenuation due to fiber wrapped around a mandrel of a specified diameter.
Zero Dispersion Wavelength (λ0): 1304 nm ≤λ0≤1324 nm
Zero Dispersion Slope (S0): ≤0.092 ps/(nm2*km)
* C omplies with IEC 60794-3: 2001, Section 5.5, Method 1, (m = 20,
Q = 0.01%), September 2001.
The link design value is a term ud to describe the PMD of concatenated lengths of fiber (also known as PMD Q). This value reprents a statistical upper limit for total link PMD. Individual PMD values may change when fiber is cabled. Corning’s fiber specification supports emerging network design requirements for high-data-rate systems operating at 10 Gb/s or higher.
