Corning® SMF-28e+® LL Optical Fiber
Product Information
Corning® SMF-28e+® LL optical fiber is an ITU-T G.652.D compliant optical fiber which builds on
Corning’s low loss fiber technology to enable extended networking distances for long haul, metro and
access applications. SMF-28e+ LL optical fiber offers industry leading specifications for attenuation
and polarization mode dispersion values which provide a solid foundation for new network deployments as well as upgrades to existing networks.

The PMD link design value is a term used to describe
the PMD of concatenated lengths of ber (also known
as PMDQ). This value represents a statistical upper
limit for total link PMD. Individual PMD values may
change when fiber is cabled.
