The Curtiss-Wright VME-682-1326-M5 is an unmanaged Gigabit Ethernet switch/router for VMEbus-based systems operating in demanding aerospace, land, and maritime environments. Built on the Broadcom StrataXGS III multi-layer switch chip, it delivers 64 million packets per second aggregate switching capacity and supports wire-speed forwarding across up to 24 10/100/1000 Mbps Ethernet interfaces. The module includes two 10 GbE XAUI ports for high-speed backbone connectivity and switch-to-switch expansion, with flexible port configurations available in 12, 20, and 24 GbE combinations.
## Technical Specifications
