Corning intros bendable SMF-28 optical fiber

Corning introduced its SMF-28 Contour optical fiber featuring enhanced bend resilience, network compatibility, and industry-leading low loss characteristics.


  • Superior bendability designed to reduce the impact of errors during installation and optimize reach in densely cabled environments where 5G networks are being deployed. SMF-28 Contour fiber is an ITU-T G.657.A2 fiber that has 10 times the macrobend resilience of G.652.D fibers and seven times the macrobend resilience of G.657.A1 fibers. The associated increase in microbend resilience enables dense, high-fiber-count cables needed to meet the demands of future high-capacity networks.
  • Exceptional compatibility with legacy networks while providing superior bend protection, which can mean up to 50% faster installation by minimizing corrective splice-loss work. Other G.657.A2 fibers also provide bend protection but with a compromised, lower mode field diameter. SMF-28 Contour fiber does not compromise, providing both G.657.A2 bend protection and a matched 9.2-micron mode field diameter in the same product.
  • Wide spectrum and industry-leading low-loss transmission across all the wavelengths that constitute the communication systems of today and tomorrow. First, SMF-28 Contour fiber’s industry-leading low attenuation delivers 10% longer reach in all networks and up to 20% wider access-network coverage. Second, SMF-28 Contour fiber’s bend loss protection enables up to twice the network reach in new long-wavelength FTTH systems. Together, these features enable larger FTTH subscriber areas and greater revenue potential.

SMF-28 Contour fiber is available in a standard 242-micron configuration and a smaller 190-micron configuration. 

Corning says smaller-diameter designs are increasingly important because while bandwidth demands have grown, the space available for network infrastructure has not. The 190-micron version of SMF-28 Contour fiber enables smaller cables with higher fiber counts – maximizing use of existing infrastructure

“Corning’s revolutionary SMF-28 Contour optical fiber is the latest example of our ability to solve tough industry challenges,” said Dr. Bernhard Deutsch, vice president and general manager, Corning Optical Fiber and Cable. “Operators today are looking to deploy future-ready networks as efficiently as possible, often in densely cabled environments, and we’ve designed this new product to answer those needs. Fifty years after Corning scientists invented the first low-loss optical fiber, we’re proud to help drive a new era of industry growth and network transformation.”
