Rugged 10/40 Gigabit Ethernet OpenVPX switch for military applications introduced by Kontron

Posted by John Keller

ECHING, Germany, 25 Sept. 2013. Kontron in Eching, Germany, is introducing the rugged VX3920 10/40 Gigabit Ethernet switch to enhance and standardize data throughput in network-centric OpenVPX applications. The IPv4/v6 VPX switch is an backbone and infrastructure building block for COTS systems in various mobile and stationary ground-based naval and airborne applications.

The managed layer 2/layer 3 switch for military embedded systems has a data plane with 24 high-throughput 10 gigabit-per-second ports that users can scale through channel bundling to 40 gigabits per second bandwidth. The card also enables systems designers to replace other individual data buses.

Application areas include high-performance embedded computing (HPEC) systems for radar, sonar and image processing, vetronics, and rapidly deployable networks for flexible communication in the field.

With data throughput as fast as 60 gigabits per second, the card also enables networking for complex system clusters on larger military intelligence and surveillance applications such as naval vessels.

The VX3920 is a non-blocking L2/L3 gigabit switch that offers 24x 10 gigabits per second ports to the backplane. These also can be bundled in groups of four on data leads with 40 gigabits per second.

For system interconnection 2x SFP+ cages for 10 Gigabit Ethernet are offered on the front. These can be used with copper cables or fiber-optic cables for long-distance networking.

An optional rear switch module conducts a 40-gigabit-per-second Ethernet QSFP+, two 10 gigabits per second SFP+, and one RJ45 1000Base interface. On the front side is a separate 1000 base RJ45 port available for switch-management via SNMP, telnet, and command line interface.

For management and debugging is an EIA-232-port that also can be routed to the backplane. Two master/slave capable I²C buses allow communication with Kontron's VPX chassis monitoring board.

The card comes in air-cooled versions able to operate in temperatures from zero to 55 degrees Celsius, and in rugged conduction-cooled versions that operate in temperatures from -40 to 85 C.
