ELECTRONICS:W. L. Gore & Assoc. Inc. has developed a 10m SFP+ copper cable assembly that is fully compliant with the SFF-8431 Revision 4.1 specification. Gore’s SFP+ (Small Form-factor Pluggable) offering can go 3 to 5m longer than other passive options and provides a lower cost alternative to power-consuming and heat-generating SFP+ transceiver modules. In comprehensive internal testing, Gore is the only cable assembly vendor who has demonstrated this use length while still complying with the SFF specification for 10 Gbyte/sec (10 GbE, 10 FCoe).Through the use of patented GORETM EYE-OPENER+® Conductor Technology and an extremely low loss expanded PTFE cable dielectric, Gore is able to balance the dWDP (waveform distortion penalty) and VMA loss (voltage modulation amplitude) parameters to achieve results within the specification limits set forth by the SFF-8431 committee. Gore has demonstrated typical values for VMA loss of 3.95 dBe and a dWDP of 5.60 dBe. The SFF-8431 specification calls out maximum limits of 4.40 and 6.75, respectively.
Gore’s proprietary expanded PTFE is branded as GORE-TEX® in the fabrics market.
A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
