Norwegian Enterprise-Grade Energy-Saving Optical Router

NTE in Norway deploys enterprise-grade, energy-efficient optical routers using Cisco Routed Optical Networking, combining high-capacity IP routing with coherent optics for sustainable, scalable networks.

Overview of NTE's Optical Routing Solution

NTE, a Norwegian energy and telecom provider, has implemented enterprise-grade optical routers that integrate high-speed IP routing with coherent optical networking. This approach allows NTE to deliver fiber-based internet services to over 140,000 users while maintaining energy efficiency and sustainability . The routers are part of a Routed Optical Networking solution, which converges services onto a single IP layer, simplifying network management and reducing hardware footprint .

Key Features

• High-Capacity Coherent Optics: NTE uses 400Gbps coherent optical ports, enabling scalable bandwidth for streaming, gaming, and enterprise applications .
• Energy Efficiency: By integrating optical transport directly into routers, the network reduces power consumption compared to traditional separate optical layers .
• Future-Proof Scalability: The architecture supports upgrades to 800Gbps and 1.2Tbps, ensuring long-term capacity for growing data demands .
• Centralized Management: Cisco Evolved Programmable Network Manager (EPN) allows remote provisioning, monitoring, and troubleshooting from a single interface, enhancing operational efficiency .
• Sustainability: NTE emphasizes green technologies, aligning high-performance networking with reduced carbon footprint .

Technology Background

The routers leverage coherent routing technology, which merges IP and optical domains using pluggable coherent optics and advanced digital signal processing. This eliminates the need for separate transponders, reduces latency, and optimizes energy use . Similar technologies are offered by global vendors like Nokia, with pluggable optics ranging from 100G to 1.6T speeds, suitable for metro, long-haul, and subsea applications .

Applications and Benefits

• Enterprise and Regional ISPs: Provides high-speed, reliable connectivity for businesses and residential users.
• Fiber-to-the-Home (FTTH): Supports large-scale fiber deployments efficiently.
• Next-Generation Services: Prepares networks for 5G, IoT, home automation, and metaverse applications.
• Operational Efficiency: Simplified network management reduces manual intervention and operational costs.

Conclusion

Norwegian enterprise-grade energy-saving optical routers, exemplified by NTE's deployment, combine high-capacity coherent optics, energy efficiency, and scalable IP routing. This solution ensures sustainable, future-proof networks capable of meeting increasing bandwidth demands while minimizing environmental impact .
