Cisco’s nLight technology powers CESNET to reduce network costs

Infotech Lead America: CESNET, the national research and education network which connects close to 100 science, research and education institutions in the Czech Republic, is transitioning to the Cisco CRS with 100 Gbps coherent IPoDWDM solution, using Cisco’s nLight technology.

Cisco’s nLight technology enables coherent 100 Gbps transport services supporting performance of 3,000 km without the need for costly signal regeneration. IPoDWDM solutions offer service providers an innovative way to introduce 100 Gbps technology in their networks and deliver ultra-long-haul, high-speed transport services.

With nLight silicon, Cisco’s 100 Gbps solution allows operators to utilize their existing fiber plant investments while also delivering maximum performance, especially on marginal or impaired fiber segments.

The Cisco CRS elastic core architecture delivers flexible scale, transport, and services to help service providers minimize network complexity and maximize service monetization.

“Service providers and large educational and research networks around the world are preparing for the next-generation Internet and the increasing demand for video, collaboration, and distributed computing. Innovations in 100 Gbps coherent IPoDWDM and Cisco nLight technology are a testament to Cisco’s commitment to leading the industry in both Internet Protocol and optical technologies,” said Bill Gartner, vice president and general manager, High-End Routing and Optical Group, Cisco.

CESNET is the first customer to deploy Cisco’s nLight silicon, enabling 100 Gbps IPoDWDM in a production network.

“IPoDWDM is a very innovative technology that will serve as the foundation for our high-speed data services, while helping us reduce network costs and improve network operations. The Cisco CRS provides an intelligent core solution with the ability to scale up to 400 Gbps per slot, which will meet our service demands well into the future. The CRS enables reliable and continuous operation, as well as a very smooth migration path from the CRS-1 to the CRS-3 platform,” said Jan Gruntorád, managing director and member of the board of directors, CESNET.
