OFC: Corning introduces low-loss, flexible cable

Corning Incorporated has introduced the Corning SMF-28® Contour optical fibre which features increased bendability, is designed to reduce errors during installation and optimise reach in densely cabled environments where 5G networks are being deployed. SMF-28 Contour fibre is an ITU-T G.657.A2 fibre that has 10 times the macrobend resilience of G.652.D fibres and seven times the macrobend resilience of G.657.A1 fibres. The associated increase in microbend resilience enables dense, high-fibre-count cables needed to meet the demands of future high-capacity networks.

The cable features wide-spectrum and low-loss transmission across all the wavelengths, delivering 10% longer reach in all networks and up to 20% wider access-network coverage. Also, SMF-28 Contour fibre’s bend loss protection enables up to twice the network reach in new long-wavelength fibre-to-the-home (FTTH) systems. Together, these features enable larger FTTH subscriber areas and greater revenue potential.

“Corning’s revolutionary SMF-28 Contour optical fibre is the latest example of our ability to solve tough industry challenges,” said Dr. Bernhard Deutsch, vice president and general manager, Corning Optical Fibre 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 fibre, we’re proud to help drive a new era of industry growth and network transformation.”

SMF-28 Contour fibre is available in a standard 242-micron configuration and a smaller 190-micron configuration. 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 fibre enables smaller cables with higher fibre counts – maximising use of existing infrastructure.
