Corning® SMF-28® ULL optical fiber

Products fiber spray

SMF-28® ULL fiber, fully compatible with legacy single-mode fibers (G.652 compatible), has the lowest loss of any terrestrial grade fiber with maximum attenuation available between 0.17 and 0.18 dB/km at 1550 nm as well as the lowest PMD of any ITU-T G.652 compliant optical fiber featuring a ≤ 0.04 ps/vkm PMDQ link design specification. Combined, these features provide additional network margin that can be leveraged to extend span lengths between amplifiers, skip amplification sites, upgrade to faster bit rates, or lengthen the unregenerated reach.
