Adtran, an Alabama-based networking equipment manufacturer, has announced the launch of a new terabit-scale routing solution designed to bring 400G internet speeds to the network edge. The solution is aimed at improving connectivity in remote and rural areas that have historically lagged behind urban centers in high-speed internet access.

Why it matters

The rollout of 400G internet infrastructure is a critical step in bridging the digital divide and ensuring equitable access to high-bandwidth applications and services, especially for underserved communities. Adtran's new routing hardware could accelerate the deployment of these faster connections in areas that have struggled with subpar internet speeds.

The details

Adtran's new terabit routing solution features a modular design that can scale to support up to 12 Tbps of capacity. The hardware is optimized for deployment at the network edge, closer to end-users, in order to minimize latency and maximize throughput. This allows service providers to more efficiently deliver 400G connectivity to homes and businesses in rural and remote regions.

• Adtran announced the new routing solution on April 2, 2026.

What’s next

The new Adtran routing hardware is expected to begin shipping to service providers in the third quarter of 2026, with wider commercial availability by the end of the year.
