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.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
