As we kick off meetings with customers and partners at OFC 2023 this week in San Diego, I’m excited to share news today with Neutral European infrastructure carrier, Sipartech, showcasing how we are driving optical innovation taking 400G over greater distances, using less power and equipment to help our customers meet their sustainability goals.

Cisco and Sipartech Successfully Test 400G Over 1,337 km to Deliver a More Efficient Transport Network for the Future 

Cisco and Neutral European infrastructure carrier, Sipartech, announced today the successful trial deployment of a 400 Gigabits per second (400G) circuit using the Cisco NCS 5504 network convergence system together with the Cisco 400G ZR+ QSFP-DD high-power Bright optical module over 1,337 km.

For the trial, Sipartech used a Cisco chassis with the 400G QSFP-DD capable line cards over a third-party line system, with eight ROADMs, a typical ‘alien wave’ deployment for the Cisco Routed Optical Network. The routers were upgraded with the 400G QSFP-DD Bright ZR+ optics at both ends. The speed of the deployment was done within a few hours.

Power saving and sustainability benefits include:

  • Based on internal Cisco testing and calculations, the solution can draw up to 87% less power than what an external transponder-based solution would draw.
  • This model significantly reduces the number of physical hardware components needed compared to an external solution, helping to reduce the carbon emissions associated with manufacturing the equipment.

The long-haul route used for this trial in the production network was from Paris to Clermont-Ferrand to Lyon, and back to Paris over mixed fiber. Sipartech has been deploying its own fiber and optical transmission networks in France and Europe since 2008, interconnecting major data centers to ensure high-quality services.

Following the trial’s success Sipartech will use Cisco’s Bright 400G ZR+ QSFP-DD high-power module to roll out 400G transponder-free services across its network footprint to connect more international businesses and ensure quality connections.

“The simplicity of the Routed Optical Networking solution demonstrated record Bright ZR+ performance and is another proof point of the significant power and space saving customers can achieve,” said Bill Gartner, SVP/GM, Cisco Optical Systems and Optics.

“With the interoperability of Cisco’s equipment, we can deploy our next generation 400G+ services with speed, simplicity, and flexibility to meet our customers’ needs, while optimizing energy expenditure and our carbon footprint as part of our global strategy,” said Julien Santina, Sipartech CEO.
