Optical Ethernet Transceivers

Marvell (Santa Clara, CA) offers the Alaska® family of secure optical Ethernet transceivers for datacenters and carrier networks. The four products cover applications at 10G, 1G, and 100Mb Ethernet speeds. The 88X2140M quadport and 88X2120M dual-port series of 10G transceivers feature XFI 10G serial and reduced XAUI interfaces to support SFP+ applications. These 10G PHYs are suitable for dense multi-port applications such as carrier class switches and routers. The 88E1542M and 88E1522M products are designed to support 1000BASE-X and 100BASE-FX in quad-port and dual-port configurations in space-efficient packages enabling high port densities as well as modular applications.

Multicore Tools for Embedded Systems — Staying Ahead of the Game —

Building a multicore system means dealing with non-determinism. Interactions between tasks running on different cores can occur in a different order, and at a different rate from one run to the next. This makes it harder to reproduce, find, and fix bugs. It also lowers the probability that validations and QA have caught all problems.

Redesigning COTS Servers for Military Applications

Military and ISR operations are inundated with vast amounts of data collected from an expanding network of sources, including sensor data from UAS, satellites, and remote monitoring stations. Critical information must be processed quickly and reliably, and delivered in real time to command centers and forces on the battlefield. Processing this plethora of information requires a multitude of computers, many of which are outdated or on proprietary platforms. To remain sustainable, systems used for enterprise computing, field operations, warfighting, and command and control, must be continually upgraded or replaced. Many of these systems need to be integrated, consolidated, and securely linked to multiple networks.

When the Going Gets Tough...

The theaters of operation for marine, air and land vehicles continue to redefine the term “rugged environment.” No longer bound by on-board human operators, autonomous and unmanned military vehicles are now free to operate within unparalleled temperature, vibration and shock regimes. The limitation on survivability of such vehicles is defined primarily by the robustness of their internal electronics. To meet these challenges, suppliers of hardened electronic systems must employ various ruggedization techniques.

New Wiring Technology Could Reduce EMI Susceptibility in Army Helicopters

Minnesota Wire’s R&D division, Minnovate, has been awarded a Phase One Small Business Innovation Research (SBIR) contract by the U.S. Army’s Program Executive Office (PEO) for Aviation. The objective of the R&D project, titled “Lightweight EMI Resistant Wiring Solutions,” is to demonstrate and develop technologies that can reduce the electromagnetic interference (EMI) susceptibility and impact of both existing and future power wiring harnesses on Army helicopters.

Low Noise Advances in RF & Microwave Signal Analysis Platforms

Spectrum measurements are essential to RF and microwave testing. The newer signal analyzers available today deliver performance far better than those of just a few years ago. The older classic swept spectrum analyzer is a super heterodyne downconverter, perhaps with a high band front end. This downconverter feeds a filter and then an amplitude or envelope detector. The detector produces a single-ended output proportional to the magnitude of the signal, and discards phase information.

Airbrush-Fabricated Carbon Nanotube Supercapacitor Electrodes

In order for the batteries used by soldiers to provide peak power, an increase in battery size and weight is necessary, which is becoming a burden. A light, compact alternative to large batteries for supplying peak power is electrochemical double-layer capacitors. These supercapacitors have a much higher energy density than conventional capacitors. Supercapacitors also have a higher cycle life, higher efficiencies, and a higher specific power than conventional batteries. Such supercapacitors will complement batteries and fuel cells to produce hybrid systems with extended capabilities.
