Internet2 to move onto CenturyLink’s new low-loss optical fiber

by Benedict Chua, Assistant Editor

Internet2 will migrate the majority of its footprint onto CenturyLink's new low-loss optical fiber.

CenturyLink recently pulled new, low-loss optical fiber over a large portion of its national network. The installation uses an ITU-T G.652.D compliant single-mode optical fiber that is optimized for high bit rate coherent systems using advanced modulation schemes supporting 100G and above. CenturyLink also realigned amplifier spacing to create more efficient resources for optimized optical networks.


Internet2 said the move will support its new all-coherent open-line system. CenturyLink has also been selected to provide the professional services to migrate Internet2 to its new platform, which will be equipped with a flex-grid open-line system being provided by Ciena. The new contractual fiber-use agreements will extend through at least 2042. Internet2 will have the ability to reach anywhere on its domestic footprint with an unregenerated wavelength of up to 200G. Many high-use spans on Internet2’s Network will also support 400G and 800G wavelengths with existing technologies and higher bitrates are expected in the coming years as new DSP technology comes into production. Internet2 has been able to achieve unregenerated spans without employing Raman amplification, a reduction in complexity and improved efficiency both at installation and for ongoing operations.

“We believe the combination of the most advanced fiber from CenturyLink with the latest coherent transmission technologies from Ciena provides enormous opportunities to enable research and academic pursuits in the United States,” said Rob Vietzke, vice president of network services for Internet2. “Whether it is tracking the origins of Neutrinos in the Antarctic, comparing gene sequences or studying the climate, this new optical network, with its ability to span very long distances at very high bandwidths and improved efficiency, is essential to providing the best research infrastructure for data-intensive science on the globe.”

“One of America’s leading research and education organizations placed its trust in CenturyLink to upgrade its network to a high-speed, high-capacity, fiber-optic network that will support today’s leading-edge research projects,” said Sonia Ramsey, CenturyLink’s vice president for the state and local government and education market. “Internet2’s selection of CenturyLink recognizes the company’s long-standing relationship with the research and education community and our commitment to meet the community’s ever-increasing advanced technology needs.”

Internet2 to deploy open line system (OLS) from Ciena

by Benedict Chua, Assistant Editor

Internet2 will deploy a flexible grid open line system (OLS) from Ciena to transform its network to a more scalable, programmable and adaptive architecture.

The upgraded network, which connects several hundred universities, government agencies, and community anchor institutions across the U.S., strengthens Internet2 and the wider R&E community’s ability to conduct scientific research, enhance collaboration, and improve operations.

The OLS element will provide access to a highly reliable, contiguous coherent optical network that can facilitate wavelength delivery and efficient data transfer throughout the continental United States. The OLS also includes Ciena’s commitment to support wavelengths launched directly from Internet2’s member networks for transport to strategic endpoints beyond their regional footprints.

Specifically Internet2 will deploy Ciena’s latest-generation Waveserver – powered by WaveLogic 5 Extreme – programmable 200G-800G coherent optics to enable Internet2 to deploy 800G wavelengths in metro locations and support efficient 400GE interconnect over native 400G wavelengths between Internet2 points-of-presence system-wide.

Ciena said Internet2’s deployment will reduce the overall space and power footprint of the current optical add-drop locations by as much as two-thirds, contributing to a lower cost and greener network that supports substantially more capacity. Internet2 will be able to tune, control and dynamically adjust optical capacity across any path using Ciena’s Liquid Spectrum ™ analytics software. Additionally, Ciena’s Manage, Control and Plan domain controller will help improve network management and operations.
Executive Comments:

“Ciena put forth a great proposal that met Internet2’s objectives to efficiently increase capacity, increase optical reach, and support open line system use cases. Together with superior coherent modems and a proven support system, the openness, flexibility and greener profile of this network will play a key role in our ability to accelerate discoveries in the research and education community. We are delighted to have Ciena as a partner in tackling the great research and education challenges of the next decade,” stated Howard Pfeffer, President and CEO, Internet2.

“Internet2 is a trailblazer in the R&E community. They are also leaders in developing collaborative environments that are shaping how future high performance, high capacity networks will be created to fuel the digital society. Ciena worked with Internet2 to establish America’s first nationwide 100G R&E network and this latest initiative will significantly enhance Internet2’s services,” said Rod Wilson, Chief Technologist for Research Networks, Ciena.
