VITA, OpenVPX & SOSA-Aligned Ethernet Switches

Amphenol Military & Aerospace VITA, OpenVPX & SOSA‑Aligned Ethernet Switches offer high‑speed, secure network switching for embedded military and aerospace computing environments. Developed by Amphenol Military High Speed, these devices extend the organization’s expertise in harsh‑environment digital interconnects to modular networking hardware compliant with established open‑architecture standards.

Standards Alignment

Each switch design follows VITA 46 / VITA 65 (OpenVPX) mechanical and electrical interface principles and conforms to the Sensor Open Systems Architecture (SOSA) technical standard for interoperability across platforms and suppliers. This alignment ensures straightforward integration within conduction‑ or air‑cooled VPX chassis and compatibility with industry‑standard payload modules and backplanes.

Rugged Construction and Environmental Qualification

The switches employ ruggedized housings and interconnects qualified to military environmental frameworks such as MIL‑STD‑810 for shock, vibration, and temperature stability and MIL‑STD‑461 for EMI/EMC protection. This environmental sealing and electromagnetic integrity make them suitable for operation in aircraft, ground vehicle, and naval systems requiring long service life under demanding conditions.

Network and System Performance

• Layer 2 and Layer 3 switching control optimized for deterministic, real‑time network performance
• Support for Commercial Off‑The‑Shelf Ethernet standards to simplify configuration and sustainment
• Designed for high‑bandwidth data routing between mission processors, sensors, and storage subsystems
• Integrated provisions for secure data transport and network separation per defense communication requirements

Integration and Applications

OpenVPX and SOSA alignment allow these Ethernet switches to serve as modular network nodes within mission computers, avionics racks, and distributed command networks. Their mechanical format simplifies replacement and upgrade cycles, supporting long‑term system sustainment without custom requalification. With standardized interfaces and Amphenol’s ruggedized Ethernet interconnect technologies, engineers can deploy reliable networking capability across tactical edge and vehicle systems.

Selection and Support

Models vary by port count, protocol support, and thermal management style to meet unique mission needs. For program development or qualification guidance, consult Amphenol Military & Aerospace technical support resources via the Amphenol Aerospace portal.
