10/40 Gigabit Ethernet switch for network-centric OpenVPX applications

Kontron's VX3920 switch achieves a large performance boost in data throughput, reduced costs, and long-term system availability.

Kontron has designed a 10/40 Gigabit Ethernet switch to significantly enhance and standardise data throughput in network-centric OpenVPX applications. The fully managed Layer 2/Layer 3 Switch Kontron VX3920 provides 24 high-throughput 10 Gbit/sec ports to the data plane. These can be scaled through channel bundling even up to 40 Gbit/sec bandwidth. By using this new rugged switch for inter- and intra-system communication, OEMs can achieve an enormous performance boost for their applications. Also, other highly individual data buses can now be replaced. Rugged COTS systems profit from the application of Ethernet by reduced costs, comprehensive enterprise class switching functionalities and a stable technology roadmap, which can also increase long-term system availability.

With its high port density and bandwidth, the IPv4/v6 VXP switch is an ideal backbone and infrastructure building block for COTS systems in various mobile and stationary ground based, naval and airborne applications. Application areas include, for example, High-Performance Embedded Computing (HPEC) systems for radar, sonar and image processing, "vetronics" systems (vehicle electronics) as well as rapidly deployable networks for flexible communication in the field. With up to 60 Gbit/sec data throughput provided by one Rear I/O module with 40 Gbit/sec Ethernet QSFP+ and two 10 Gbit/sec SFP+, it also enables a powerful networking for complex system clusters, which are found on larger military intelligence and surveillance applications such as naval vessels.

The non-blocking L2/L3 gigabit switch offers 24x 10 Gbit/sec ports to the backplane. These can also be bundled in groups of four on data leads with 40 Gbit/sec. For system interconnection 2x SFP+ cages for 10 Gigabit Ethernet are offered on the front. These can be used with cost saving copper cables or fibre-optic cables for long distance networking. An optional rear transition module conducts a 40 Gbit/sec Ethernet QSFP+, two 10 Gbit/sec SFP+ and one RJ45 1000Base interface. On the front side, there is a separate 1000 base RJ45 port available for switch-management via SNMP, telnet
