Coriant and Corning to Demonstrate Cost-Optimized Long Reach, High Performance Data Center Interconnect

Powerful Combination of Coriant CloudWave™ Optics and Corning® SMF-28® ULL Optical Fiber Enables DWDM 200 Gbps 16QAM Transmission over 300 Kilometers without mid-span OLAs

ANAHEIM, California, 21 March 2016 – Coriant, a global supplier of SDN-enabled end-to-end transport networking solutions, and Corning Incorporated (NYSE: GLW) today announced a collaborative demonstration of dense wavelength division multiplexing (DWDM) that will be on display at OFC 2016, March 22-24, in Anaheim, California.

This live demonstration features Coriant CloudWave™ Optics (in combination with the Coriant® hiT 7300 Multi-Haul Transport Platform) 200 gigabits per second, 16QAM transmission over 300 kilometers of SMF-28® ULL fiber in a link without intermediate optical line amplifiers (OLAs). With 50 decibels of equipment loss budget, the maximum distance is approximately 20 percent longer compared to a generic single-mode fiber.

The longer reach increases the number of data center interconnect (DCI) connections that could be covered without intermediate OLAs. The DWDM transmission demonstration also showcases the scalability of the link capacity up to 25.6 terabits per second using easy-to-deploy, co- and counter-propagating laser Class 1M hybrid Raman amplifiers with integrated OTDR functionality.

As data centers become increasingly distributed and growth in cloud traffic drives demand for higher capacity DCI links, network operators face the challenge of efficiently scaling transport infrastructure while controlling network and operational costs. This challenge is compounded by more stringent OSNR requirements when increasing data rates from 100 Gbps (QPSK) to 200 Gbps using 16QAM modulation, resulting in additional mid-span amplification to meet performance requirements and end-user service quality.

"Today's dynamic cloud networking environment demands new levels of efficiency and ease of deployment as network operators face rapidly evolving optical transport reach and performance requirements," said Uwe Fischer, Chief Technology Officer, Coriant. "We are pleased to collaborate with Corning to showcase the real-world value of low cost, high capacity DCI connectivity using our innovative Coriant CloudWave™ Optics technology and Corning's best-in-class ultra-low loss fiber."

"Corning is pleased to participate with Coriant to demonstrate how the selection of advanced technology enables high-speed data delivery in DCI networks," said Dr. Merrion Edwards, director of Market and Technology Development, Optical Fiber and Cable, Corning. "Deploying Corning's SMF-28 ULL fiber with Coriant's technology delivers extended reach that can eliminate the need for amplifiers, saving both capital and operational costs for the network owner."

Designed for application across Coriant's end-to-end packet optical transport portfolio, Coriant CloudWave™ Optics is a key photonic layer technology solution that combines a leading signal processing engine, optimized integrated photonics, and embedded software intelligence to bring a new level of optical performance, efficiency, and scalability to infrastructure networks facing unprecedented traffic growth. SMF-28 ULL fiber has the lowest loss of any terrestrial grade single-mode fiber with a typical attenuation of 0.16 dB/km at 1550 nm. SMF-28 ULL fiber has been deployed around the world in some of the most challenging environments, allowing network operators to skip amplification sites, upgrade to faster bit rates, add network components for improved flexibility, and lengthen the distance between regenerators.
