Corning® SMF-28e+® Optical Fiber Product Information Coming's SMF-28e+® optical fiber is the industry leader in comprehensive single-mode fiber performance for metro and access networks. It is ITU-T G.652.D-compliant and fully backward compatible with legacy standard single-mode fibers. SMF-28e+ fiber is built on Coming's solid foundation of quality and proven performance. Since we brought the first fiber to market more than 40 years ago, our demonstrated leadership in single-mode fiber Contact your sales the Optical Fiber Customer Service Department: Email: [email protected] Please specify the fiber type, attenuation, and quantity when ordering. Optical Specifications Maximum Attenuation Maximum Value* *Maximum specified attenuation value available within the stated ranges. **Attenuation post-hydrogen aging according to IEC Alternate attenuation offerings available upon request. The attenuation in a given wavelength range does not exceed the attenuation of the reference wavelength (X) by more than the value a. Macrobend Loss Wavelength Induced Mandrel Number *The induced attenuation due to fiber wrapped around a mandrel of a specified diameter. Point Discontinuity Point Discontinuity Cable Cutoff Wavelength {XJ Mode-Field Diameter Dispersion Value Zero Dispersion Wavelength (X0): Zero Dispersion Slope (S0): < 0.092 ps/(nm2-km) Polarization Mode Dispersion (PMD) Value (ps/Vkm) PMD Link Design Value Maximum Individual Fiber PMD ♦Complies with IEC 60794-3: 2001, Section 5.5, The PMD 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. SUPERSEDES: AUGUST 2009 I I I ^upercoatings
