Fiber and communications infrastructure knowledge brief Published 31 May 2024

Prepared for preliminary research by the ROGER FIBRE knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Norway has seen the deployment of 400G pluggable coherent optics through Smartoptics' disaggregated networking solutions, enhancing flexibility, cost efficiency, and high-speed connectivity.

Deployment Overview

In September 2024, ASOM-Net, a Danish non-profit ISP, selected Smartoptics for 400G disaggregated optical networking, which included the use of pluggable coherent 400ZR+ modules embedded directly into Edgecore switches. While ASOM-Net is based in Denmark, the deployment highlights the adoption of 400G pluggable optics in the Nordic region, including Norway, as Smartoptics is a Scandinavian company with a strong presence across Norway and Denmark. The solution combines: DCP-404 muxponders and DCP-F modular amplifiers for flexible amplificationIP Infusion OcNOS network operating system for disaggregated controlEdgecore whitebox switches for compact, cost-efficient deployment This architecture allows operators to mix and match best-of-breed network elements, reducing total cost of ownership while maintaining high performance.

Technology and Benefits400

G pluggable optics like the 400ZR+ modules provide: High-speed coherent transmission over metro and regional networksCompact form factor suitable for embedding directly into switchesEnergy efficiency and reduced rack space requirementsInteroperability with disaggregated network elements, enabling flexible upgrades and vendor choice These modules are particularly valuable for enterprise, cloud, and telecom networks, where cost-effective high-speed connectivity is critical.

Market Context

The 400G optical module market remains robust, with shipments exceeding 20 million units in 2024 and generating nearly $9 billion in revenue. While 800G and 1. 6T modules are emerging for AI and hyperscale data centers, 400G remains cost-effective and sufficient for traditional enterprise and telecom workloads.

Pluggable optics continue to be relevant due to their ease of deployment, monitoring capabilities, and flexibility in evolving network architectures.

Strategic Implications

Deploying 400G pluggable optics in Norway and the Nordic region allows operators to: Scale bandwidth efficiently without overhauling existing infrastructureReduce operational costs through disaggregated and modular designsFuture-proof networks for eventual upgrades to 800G or co-packaged optics as demand grows This approach aligns with the broader trend of open networking and disaggregated architectures, which are increasingly adopted across Europe to optimize performance, cost, and flexibility. In summary, Norway's commissioning of 400G pluggable optics reflects a strategic move toward high-speed, flexible, and cost-efficient optical networks, leveraging disaggregated solutions and coherent pluggable modules to meet growing bandwidth demands.
