The Curtiss-Wright VPX6-688 Gigabit Ethernet switch was designed to provide a complete networking solution for VPX systems. Suitable for a wide range of embedded computing and vehicle network applications, the VPX6-688 provides 24 ports of IEEE 802.3 compliant 1000BASE-T Gigabit Ethernet to the backplane. Optional optical interfaces provide four 1000BASE-SX Gigabit links.

Ensuring that mission-critical data is given priority as platform networks become more congested calls for switches with the latest networking features. Today’s switches must manage quality of service, ensure efficient multicast stream distribution and enforce policies for filtering and limiting data rates. The VPX6-688 incorporates robust, multi-layer switching services based on proven enterprise-class networking software, with regular updates to help systems keep pace as requirements evolve.

Connecting embedded systems to intra-platform and wide-area networks also introduces a range of cybersecurity threats. Protecting against the ever-evolving array of vulnerabilities requires products designed for network security, with regular maintenance to address new threats. With the VPX6-688, Curtiss-Wright is delivering a networking solution that delivers the latest switching and routing features, and is also designed to address current and future cybersecurity challenges.

To support lifecycle extensions and upgrades, the VPX6-688 is a pin-compatible replacement for the earlier VPX6-684 switch products and support by lifecycle management services from Curtiss-Wright.
