Why the network edge needs 400G today

Traffic at the network edge is growing fast, and many existing networks weren’t built to handle it efficiently. Where access networks like fiber broadband and mobile backhaul connect to aggregation and core networks, this challenge is especially noticeable. As traffic grows, simply adding more 100Gbit/s interfaces increases space, power consumption and operational complexity, making traditional scaling models inefficient and costly.

“Modern” routers haven’t really changed that equation. They’re often expensive, power-hungry and just all around large, which adds cost and complexity even when they’re marketed as next-generation platforms.

At Adtran, we’re applying real-world experience to the next generation of edge routing. Building on proven 100Gbit/s edge router deployments, including work with the Telecom Infra Project, our edge router solution introduces 400Gbit/s-enabled interfaces at the network edge, delivering high capacity while reducing space and power requirements compared to traditional designs. It provides high-capacity routing without the cost or power draw of older, oversized systems. With integrated MPLS routing, coherent optics and a common software foundation for automation, Adtran enables long-term growth while keeping the network flexible, efficient and future-ready, supporting a clear path to Terabit-scale edge capacity as demand continues to grow.

Cost-effective 400G edge routing at scale

When it comes to edge networking, performance doesn’t have to come at a premium. While many vendors now offer 400Gbit/s-capable edge platforms, solutions can cost over $100K per unit, often before software is included, with comparable capabilities to Adtran’s edge routers.

In contrast, Adtran’s edge routers deliver reliable high-capacity routing with 400Gbit/s interfaces at a fraction of the cost. The solution spans compact, cabinet-ready platforms for space-constrained edge deployments as well as high-density systems designed for large-scale aggregation environments, ensuring the right fit across different edge scenarios.

Adtran’s high-density, low-cost platforms make it easier to add capacity without introducing expensive hardware or complex integrations. Edge aggregation doesn’t have to be expensive – our solution makes scaling both affordable and simple.

Seamless scalability from 10G to 400G

From 5G backhaul to fiber broadband aggregation, Adtran’s edge router solution is built to scale as traffic increases.

With native support for 10, 100 and 400Gbit/s speeds, our routers allow networks to scale without disruptive hardware upgrades. Built-in automation with Adtran’s carrier-grade network operating system (NOS) provides a consistent software foundation across edge routing platforms. This simplifies provisioning and management as networks scale. By decoupling software from hardware, the solution allows operators to deploy, expand and evolve edge routing platforms without changing their operational model.

Whether you’re handling growing traffic volumes or deploying new services, Adtran’s solution provides the flexibility and scalability you need to stay ahead of future demands, without costly upgrades or downtime. This future-proof design saves you from the need for frequent, expensive hardware refreshes.

Simplified edge architecture with integrated routing and coherent optics

Adtran’s edge router solution, with 400Gbit/s interfaces, is designed to simplify your network by seamlessly integrating routing capabilities with coherent optics.

With plug-and-play integration of ZR/ZR+ coherent optics, our routers enable high-capacity 400Gbit/s connections directly from the router. This easy integration supports seamless scaling of your network to 400Gbit/s speeds, while maintaining compatibility with modern MPLS traffic management.

Integrated coherent optics, combined with optional IP OLS capabilities, extends the reach of 400Gbit/s traffic and enables high-capacity packet edge transport, amplifying signals to 120km+. This approach enhances the routing platform without introducing additional complexity, making it easier to scale without adding unnecessary equipment.

As your network needs grow, the IP OLS system can scale to 800Gbit/s, allowing the network to scale easily when you’re ready. The modular nature of our solution means you can add only the components you need, avoiding unnecessary complexity and keeping your network efficient and adaptable.

Why Adtran leads in cost-effective 400G edge routing

High-capacity hardware alone doesn’t solve the challenges of scaling the network edge. Throughout this blog, we’ve talked about cost-effective hardware, seamless scalability and simplified integration. What makes those advantages practical at scale is a combination of high-capacity hardware, integrated optics and a consistent software foundation that simplifies operations as networks grow. 

• A consistent software foundation across the edge: Delivers a unified feature set, command structure and automation framework across deployments, reducing operational complexity as networks scale from 10Gbit/s to 400Gbit/s.
• Automation that makes 400Gbit/s practical: Simplifies provisioning, configuration and lifecycle management, reducing cost and enabling service providers to deploy high-capacity routing without adding complexity
• Hardware flexibility without lock-in: Allows independent evolution of software and hardware, empowering operators to deploy, expand and refresh edge routing platforms without changing their operational model.
• Integrated routing and optics: Combines plug-and-play coherent optics and IP OLS capabilities within the routing architecture to simplify network design with fewer devices and fewer failure points.
• A complete ecosystem: Adtran delivers an end-to-end portfolio of hardware, software and services, simplifying operations from access to core.
