Corning SMF-28 Ultra Optical Fiber-first to combine improved attenuation and bend performance in one single-mode fiber

Corning today announced its latest single-mode optical fiber innovation, Corning SMF-28 Ultra fiber. This new, premium single-mode optical fiber is the first in the market to combine the benefits of industry-leading attenuation and improved macrobend performance in one fiber. The improved macrobend performance provides greater margins for bends that regularly occur in the field during installation and maintenance, and allows for the design and deployment of smaller and lighter cables which can improve duct utilization, enable smaller enclosures, or reduce pole/tower loading in aerial deployments.


The improved attenuation of SMF-28 Ultra fiber provides additional margin that can be used to extend spans, lengthen the distance between regenerators, increase the allowable number of cable-cuts, or allow for the broader use of pre-connectorized solutions. Designed for high performance across the range of long-haul, metro, access, and fiber-to-the-home (FTTH) network applications, the new Corning optical fiber is fully backward compatible with the installed base of legacy single-mode optical fibers.
