Parvus introduces rugged fiber optic Gigabit Ethernet switch subsystem

DuraNet 1268

SALT LAKE CITY, Utah, 26 May 2012. Parvus, a subsidiary of Eurotech, has released tactical fiber optic media support for the DuraNET 1268, a rugged Layer 2 Gigabit Ethernet switch subsystem equipped with ten triple-speed 10/100/1000Mbps ports for connecting IPv4 and IPv6 compatible sensors and computing devices onboard network-centric manned and unmanned vehicles and aircraft. The DuraNET 1268 is a ruggedized commercial-off-the-shelf (COTS) device and is designed for SWaP (size, weight and power) efficenicy. The DuraNET 1268 is suited for instances that require military embedded systems, such as C4ISR technology and situational awareness programs. The device features no moving parts, a low-cable internal design, industrial temperature grade components,  EMI filtering, and a sealed dust-and-waterproof aluminum chassis with an isolated MIL-STD-1275/704 power supply to protect against voltage surges, spikes and transients.


The Gigabit Ethernet interfaces are brought out over rugged MIL-DTL-38999 connectors on the front panel and on optional Tactical Fiber Optic Cable Assembly (TFOCA II) connectors on the rear. These optical interfaces were selected by the U.S. ARMY WIN-T program as the standard fiber optic connector for military tactical deployable networks.

Managed and unmanaged switch configurations are available for configurable or "plug and play" Gigabit Ethernet LAN applications. The base DuraNET 1268 was qualification tested for extreme MIL-STD-461F EMI/EMC and MIL-STD-810G thermal, shock, vibe, humidity, altitude, and ingress conditions, as well as RTCA/DO-160G airworthiness tests for low temperature and high altitude operation.

The DuraNET 1268 features an onboard microprocessor for local/remote control and port monitoring, as well as support for Quality of Service traffic prioritization, Virtual Local-Area Network (VLAN) trunking, Telnet remote Command Line Interface (CLI) management, and Rapid Spanning Tree redundancy. The unit integrates recoverable data zeroization for declassifying switch data, along with RS-232 CLI and Ethernet management ports. Status LEDs indicate zeroization signal, power, and port link/speed/activity.

DuraNET 1268 subsystems with fiber optic support will start sampling before 60 days. The datasheet for the system can be found here.
