Corning® SMF-28® Ultra Optical Fiber - Bare Corning Fiber in Roll, with Connectorized Optional

 

"The price above is for one kilometer length"

 

Corning® SMF-28® Ultra optical fiber was the first to market to combine the benefit of industry-leading attenuation and improved macrobending performance while maintaining compatibility with the existing installed fiber base. This full-spectrum all-in-one fiber is advantaged for operation in fiber to the home (FTTH), mobile, access, metro, regional and long haul networks. SMF-28 Ultra fiber has bend performance that exceeds Recommendation ITU-T G.657.A1, and is compatible and fully compliant with Recommendation ITU-T G.652.D.
