Lumen Technologies announced NorthLine, a new low-latency fiber route directly connecting Seattle and Minneapolis to support AI-driven data movement across a northern U.S. corridor.
The route will support 100G and 400G wavelength services and integrate with Lumen’s national network. Lumen expects NorthLine to become available by the end of 2026, giving enterprises, cloud providers, and AI infrastructure operators a more direct path between the Pacific Northwest and central U.S. markets.
NorthLine will be delivered through Lumen RapidRoutes, the company’s pre-engineered route program with validated capacity and a 20-day service level agreement for qualified deployments. Lumen said the route will use new optical technologies that improve fiber efficiency while creating a path toward future 800G and 1.6 Tbps wavelengths.
- Route: Seattle to Minneapolis
- Availability target: End of 2026
- Services: 100G and 400G wavelengths
- Future roadmap: 800G and 1.6 Tbps wavelengths
- Target users: Enterprises, cloud providers, AI infrastructure operators
- Deployment model: Lumen RapidRoutes with validated capacity and 20-day SLA for qualified deployments
- Strategic role: Adds geographic diversity across the northern U.S. and supports transpacific traffic flows from West Coast landing points into central U.S. markets
“Enterprises are building for what comes next —more AI workloads, more distributed infrastructure, and more demand for low latency capacity in the right places,” said Lumen Chief Commercial Operations Officer Kye Prigg. “We’re not just building routes; we’re building a connected national fabric. NorthLine will deliver a new northern route paired with the predictable, high-capacity services customers need to make more confident infrastructure decisions.”
🌐 Analysis: NorthLine reflects a broader shift in U.S. backbone design as AI traffic increasingly moves between distributed compute sites, cloud regions, data center campuses, and power-rich emerging markets. The route also fits Lumen’s recent positioning around AI-era network infrastructure, where long-haul fiber, wavelength services, rapid provisioning, and future 800G/1.6 Tbps optical transport become central to cloud and AI workload placement decisions.
