RAD Debuts 400G Ethernet Platform for DCI, Enterprise Connectivity

Why It Matters

The platform delivers the bandwidth and security needed for AI‑driven data transfers, giving CSPs a competitive edge in the rapidly expanding DCI market.

Key Takeaways

• RAD introduces ETX‑2i‑400G 400 Gbps Ethernet platform.
• Supports AI‑driven DCI with low latency.
• Includes quantum‑ready security (QKD, PQC).
• Targets CSPs for high‑capacity, SLA‑based services.
• Demo at MWC Barcelona March 2026.

Pulse Analysis

The surge in artificial‑intelligence model training has amplified demand for ultra‑high‑speed data‑center interconnect (DCI) solutions. Traditional 100 Gbps links are increasingly strained as datasets grow into petabytes, prompting vendors to accelerate Ethernet standards. RAD’s ETX‑2i‑400G arrives at a pivotal moment, offering a 400 Gbps backbone that can move massive AI workloads between sites while preserving low latency, a critical factor for keeping GPU farms productive.

Beyond raw throughput, the ETX‑2i‑400G distinguishes itself with a crypto‑agile architecture. By integrating Quantum Key Distribution (QKD) and post‑quantum cryptography (PQC), the platform anticipates future security threats and aligns with emerging carrier‑grade certifications such as Mplify’s AI‑ready program. Its modular QSP‑DD interfaces enable scalable deployment, allowing service providers to incrementally expand capacity without overhauling existing edge infrastructure. This blend of performance and forward‑looking security positions the device as a cornerstone for next‑generation carrier Ethernet services.

For communications service providers, the announcement signals a strategic opportunity to monetize high‑value, SLA‑based offerings for enterprises and hyperscalers. The ability to guarantee secure, high‑capacity links can differentiate CSPs in a crowded market where latency and data integrity are paramount. RAD’s showcase at Mobile World Congress will likely attract operators eager to future‑proof their networks, making the ETX‑2i‑400G a catalyst for broader adoption of 400 G Ethernet across global DCI ecosystems.
