    DC Data Centers: A Necessary Paradigm Shift for Sustainability and Savings

    DC power supplies enable leaner, more powerful data center system architectures that — through skillful planning — can also mitigate total system cost. But first, we must make a paradigm shift. DC data centers Vast amounts of unused electricity simply disappear in data centers, lost to tedious, continuous, and ultimately unnecessary conversion and transformation processes. But Read More >>

  • New VITA 46 Updates for High-Speed Interconnects

    ANSI has ratified updates to an embedded computing standard that has important ramifications for military electronics. The American National Standards Institute (ANSI) recently ratified the VITA 46.0 (commonly known as VPX) baseline standard for critical embedded computing. VITA 46, or VPX, provides Versa Module Europa bus (VMEbus) based systems with support for switched fabric network topologies over a new Read More >>

Photonic Systems Manufacturing Consortium Enlists Participation in a 10-Year Roadmap

The Photonic Systems Manufacturing Consortium enlists participation in a 10-year roadmap for the development and manufacturing capabilities needed to produce low-cost, high-volume, integrated photonic systems. The Photonic Systems Manufacturing Consortium (PSMC), a collaboration of the International Electronics Manufacturing Initiative (iNEMI) and the MIT Microphotonics Center, is enlisting the participation of key industry stakeholders in its development of Read More >>

FCI's QSFP+ 40Gbase CR4 cable assembly

The Future of Copper 40-Gigabit Ethernet

The first standard for 40G structured cabling, IEEE 802.3ba, only covered fiber optics and short-reach copper twinax. Now an active task force is developing a copper twisted-pair standard. Here is a look at the technology and potential market for copper 40-Gigabit Ethernet. While the TIA touts its premise wiring standards as “application non-specific,” the industry Read More >>

Multi-Contact Coax Connectors and VITA Standards

Using multi-contact coax connectors and VITA standards can preserve space on the front panel and facilitate insertion/removal of cards for installation, repair, and upgrades. A growing trend in electronic packaging for military and aerospace applications is the availability of multi-contact coaxial interconnects. A key driver is the desire to provide RF disconnect capability at the backplane/daughtercard Read More >>

Meeting Medical Industry Standards for Cable Design

With no medical industry standards for cable, the industry adopts voluntary specifications to ensure patient safety. The medical device industry tolerates a much smaller margin of error than most other industries. Medical devices are highly precise and sensitive instruments. As such, medical interconnect cable, and more significantly, the material used in such apparatuses, must be Read More >>
