6U VPX SOSA-Aligned VITA 91 Ethernet Switch

The Open.Tech 6U VPX SOSA-Aligned Ethernet Switch is a rugged, high-speed Layer 2/3 managed switch designed to meet the demands of next-generation C5ISR, SIGINT, EW, and sensor fusion systems. Built on the VITA 91 profile and fully SOSA-aligned, it delivers up to 10.4 Tbps of switching throughput across 216 or 240 channels, supporting both 25G and 50G Ethernet over fiber.

This VPX switch is available in two configurations:

• CF-02W600-10X: 240 total channels – 184x 50G backplane + 48x 25G front panel

• CF-02W600-11X: 216 total channels – 184x 50G backplane + 24x 50G front panel

Designed for OpenVPX systems in harsh environments, the switch supports conduction or air cooling, operates from -40°C to +85°C, and is engineered to meet stringent shock, vibration, altitude, and EMI requirements. Its robust mechanical design includes MIL-grade extraction levers, wedgelocks, and SOSA-compliant MIL-HD2 connectors with a 1.80mm pitch and support for 56Gb/s PAM4 signaling.
