IP Infusion and EPS Global moved eww ITandTEL’s backbone to 400G capacity, positioning the Austrian IT and telecom provider for long-term growth and improved operational efficiency. The company upgraded its MPLS network with IP Infusion’s OcNOS-SP-PLUS, shifting from a 100G architecture to an open 400G IP-over-DWDM design built around coherent ZR+ optics. The deployment spans whitebox hardware from UfiSpace and Edgecore, enabling a fully disaggregated model across a multi-vendor optical environment.
eww ITandTEL, which operates secure data centers and fiber assets across Europe, sought a scalable system that could meet rising bandwidth demand without the cost and lock-in of traditional chassis platforms. By integrating OcNOS across 400G ZR+ circuits, the operator boosted backbone capacity while standardizing control, visibility, and automation across its domains. EPS Global supported the rollout with sourcing, configuration, and integration services.
The upgrade underscores growing momentum behind open networking in regional service providers, especially as 400G ZR/ZR+ adoption accelerates across IPoDWDM backbone designs. eww ITandTEL said it expects the new architecture to strengthen network sovereignty, resiliency, and long-term economics.
• eww ITandTEL upgraded its MPLS backbone from 100G to 400G using IP Infusion’s OcNOS-SP-PLUS.
• Deployment uses 400G ZR+ coherent optics across multi-vendor DWDM spans.
• Whitebox platforms include UfiSpace S9600-56DX, S9510-28DC and Edgecore AS7946-30XB.
• Open networking replaces legacy chassis systems and avoids vendor lock-in.
• EPS Global provided distribution, integration, and supply-chain coordination.
• Architecture improves bandwidth, resiliency, operational visibility, and cost efficiency.
“The shift to an open, OcNOS-driven 400G IPoDWDM backbone gives us the control, visibility, and operational efficiency we need to keep our services consistently stable and ahead of demand,” said Christoph Ehmayer, Team Lead Network/System Engineer, eww ITandTEL.
🌐 Analysis
This deployment reflects a broader shift toward IPoDWDM and ZR+ optics among regional operators seeking to scale affordably without adopting large proprietary routing platforms. IP Infusion has expanded its footprint in Europe through disaggregated transport wins, while competitors such as Arrcus and Drivenets also pursue operators moving to open architectures. EPS Global’s continued role highlights the importance of integration and supply-chain orchestration as multi-vendor strategies become mainstream.
