Corning® SMF-28® ULL Optical Fiber

Deployed Around the World

Corning® SMF-28® ULL Optical Fiber

Corning SMF-28® ULL fiber has the lowest loss of any terrestrial grade single-mode fiber with a maximum attenuation of 0.17 dB/km at 1550 nm.

SMF-28 ULL fiber has been deployed around the world in some of the most challenging network applications, where ultra-low attenuation can be leveraged to extend network span lengths, skip amplification sites, upgrade to faster bit rates, add network components for improved flexibility, and lengthen the distance between regenerators.
