OpenVPX

OpenVPX is the backbone of modern modular embedded systems for defense, aerospace, and rugged industrial applications. Based on the VITA 65 specification, OpenVPX defines a system-level architecture for interoperable VPX modules, ensuring that payloads, switches, and backplanes from different vendors can communicate seamlessly within a unified infrastructure.

At Open.Tech, we offer a complete portfolio of OpenVPX-compliant solutions—from rugged Ethernet switches and fiber transceivers to VITA 67.3 backplanes, test chassis, and high-speed cable assemblies. All of our products are built to meet or exceed the rigorous performance, interoperability, and durability standards demanded by OpenVPX and its extensions like SOSA and CMOSS.

What Is OpenVPX?

OpenVPX is a modular embedded computing standard developed by the VITA Standards Organization (VSO) to improve interoperability between VPX system components. While VPX (VITA 46) defines the mechanical and electrical interfaces, OpenVPX (VITA 65) introduces a system-level architecture that standardizes slot profiles, backplane configurations, and communication planes across vendors.

OpenVPX enables high-speed serial communication between plug-in cards using technologies such as PCIe, Ethernet, and RapidIO. It supports 3U and 6U form factors and is optimized for use in extreme environments, including ground vehicles, aircraft, and shipboard systems.

Benefits of OpenVPX:

• Standardized slot and backplane profiles

• Support for high-speed serial protocols (10G/25G/50G Ethernet, PCIe Gen4+)

• Rugged design for conduction, air, and liquid-cooled environments

• Backward and forward compatibility via clearly defined profiles

• Foundation for emerging SOSA, CMOSS, and VITA 91 systems
