Corning® SMF-28® Contour optical fiber delivers all the features needed to increase network efficiency for today and tomorrow. Combining a low outer diameter of 190 µm with bend resilience that aligns with ITU-T G.657.A2 requirements at small bend radii, this high-performance fiber enables smaller, lighter, more sustainable optical solutions. SMF-28 Contour fiber is a wide spectrum, low attenuation fiber that has a 9.2 µm standard mode field diameter for compatibility with existing installed fibers and efficient splicing.
