Kontron announces VX3406, 3U VPX card with six Ethernet ports

For harsh defense and aerospace environments, enables seamless integration of multiple IP-based sensors and communication modules

Toulon, France, June 2, 2025 – Kontron, a leading global provider of IoT/Embedded Computing Technology (ECT), today announces the VX3406, 3U VPX Ethernet board for harsh environments, the first to offer up to six 1000BASE-T ports each managed by a dedicated Ethernet controller, ensuring zero bandwidth contention, superior fault and cybersecurity  isolation, and precise traffic prioritization.

Designed for C4ISR systems, unmanned platforms and any connected warfare scenario, the ruggedized, low power consumption VX3406 ensures high resilience, secure segmentation and real-time data handling across harsh environments. 

The VX3406 integrates a powerful 8-port, 8-lane PCIe Gen3 switch offering users the ability to leverage up to four independent 1G/2.5G ports fully supporting TSN/IEEE1388 along with up to two dedicated 1G copper ports, enabling a total of six concurrent 1000BASE-T ports for unrivalled network expansion.

Easy integration of TSN-capable controllers across its multiple independent ports avoids the need for legacy deterministic protocols or external switches, ensuring guaranteed delivery and timing precision for demanding embedded aerospace and defense environments. This makes the VX3406 ideal in use cases where low-latency, jitter-free deterministic Ethernet communication is a prerequisite, including real-time sensor fusion, mission system coordination, control-loop communications and synchronized audio/video streams.

"As the first and only 3U VPX Ethernet card on the market offering six totally independent ports, the Kontron VX3406 raises the bar for communications performance, connectvity and flexibility in harsh defense and aerospace environments, with the added advantage of being designed and supported from France and therefore free of ITAR restrictions," said Christophe Ferrande, Kontron Product Manager. 

The conduction cooled Kontron VX3406 is now available with an air-cooled variant available on request.
