The Parvus DuraNET 20-11 is an ultra-small form factor (SFF) rugged Commercial Off the Shelf (COTS) 8-port Gigabit Ethernet (GbE) switch optimized for extremely demanding size, weight and power (SWaP) constrained vehicle and aircraft platforms exposed to harsh environmental and noisy electrical conditions (e.g. high altitude, extreme shock and vibration, extended temperatures, humidity, dust and water exposure, noisy EMI, and/or dirty power). The unit boasts an ultra-miniature “pocket sized” design with a physical size of roughly 10 in3 in volume, 0.50 lb in weight, and 5W typical power consumption. Bringing out Ethernet, power, console, and zeroize signals over micro-miniature MIL circular connectors, the unit is well suited for low size and weight applications with demanding electromagnetic compatibility (EMC) requirements. Validated for military and civil aircraft use as well as ground vehicle installations, the 20-11 features integrated EMI and power filtering for the input voltages, spikes, surges, transients, and EMI/EMC compatibility requirements of MIL-STD- 704F, MIL-STD-1275D, MIL-STD-461F, and RTCA/DO-160.

Not only does the DuraNET 20-11 deliver an ultra-low SWaP-optimized rugged design with IP67 dust and water ingress protection, but it also features the latest in carrier-grade, fully managed Ethernet switch technology to deliver new situational awareness and C4ISR capabilities for unmanned air and ground vehicles (UAVs, UGVs) and other SWaP constrained platforms deploying network connectivity at the tactical network edge. This fully managed, Layer 2+ switch provides a powerful set of carrier-grade networking features, including support for IPv4 and IPv6 multicast traffic, Virtual Local Area Networks (VLANs), port control (speed/mode/statistics, flow control), Quality of Service (QoS) traffic prioritization, Link Aggregation (802.3ad), Simple Network Management Protocol v1/v2/v3 management, secure authentication (802.1X, ACLs, Web/CLI), redundancy (RSTP/MSTP), precision timing (IEEE-1588v2), port monitoring, IGMP Snooping, Built-in Test (BIT), and data zeroization. The unit also supports Layer 3 IPv4/IPv6 static routing for attached WAN/ radios.

This rugged system was engineered for high reliability and validated through extensive qualification testing for extreme EMI/EMC (MIL-STD- 461F, DO-160F) and environmental (MIL-STD-810G, DO-160) conditions. Extended temperature operation from -40 to +85°C, resistance to high shock and vibration, humidity, altitude, and dust/water ingress make the DuraNET 20-11 an extremely reliable Local Area Network (LAN) switching solution for technology refresh and new platforms to connect Ethernet enabled embedded devices, including computers, cameras, sensors, and command-and-control equipment deployed in digital networked architectures at the network edge.

For applications requiring shielded Quadrax connectivity, see related DuraNET 20-12 model, which provides 6-ports of Fast Ethernet in a similar miniature form factor.
