Corning debuts first ultra-low-loss, smaller-diameter fibres for long-haul

Technologies and Products

Corning Incorporated has debuted a series of smaller, denser additions to its portfolio of long-haul fibre and cable innovations, including the world’s first submarine and terrestrial long-haul fibres in a 200-micron diameter.

The fibre and cables are designed to help network operators stay ahead of bandwidth needs driven by 5G in access networks, as well as high-performance applications like augmented reality and artificial intelligence in hyperscale data centres. They are also designed to simplify installation, extend capacity and reach, and provide enhanced density for today’s space-constrained environments.

The new products include:

A pair of first-to-market 200-micron fibres for cost-effective long-distance reach. Corning® SMF-28® ULL fibre is a G.652-compliant, ultra-low loss, future-ready solution for terrestrial long-haul networks. Vascade® EX2000 fibre is an ultra-low loss, large effective area fibre for submarine SDM systems. Both new smaller diameter fibres enable up to 33% more capacity per cable with a lower cost per bit than current solutions.

Corning® RocketRibbon™ 200 extreme-density cable, the newest addition to Corning’s award-winning RocketRibbon cable line. Utilising Corning® SMF-28® Ultra 200 fibre, it delivers the same fibre counts as other versions of RocketRibbon cable, but in diameters up to 15% smaller – reducing material and labor costs and speeding deployment in carrier and data centre interconnect networks. RocketRibbon 200 comes with fibre counts of 1,728 and 3,456.

Corning’s new ultra-compact Fibre Array Unit (FAU), which provides higher levels of fibre-to-the-chip coupling density and performance. Leveraging Corning’s Reduced-Clad Bend-Insensitive (RCBI) fibre, this new family of FAUs is designed to help switch manufacturers solve bandwidth and density bottlenecks in data centre switches.

“We are excited to launch our newest smaller-diameter fibre and cable to support data centre, access and submarine network operators in delivering a denser network while maintaining easy and proven installation methods,” said Dr. Bernhard Deutsch, vice president and general manager, Corning Optical Fibre and Cable. “These innovations are enabled by close collaboration with our customers and Corning’s unique capabilities across fibre, cable and connectivity.”
