The Future of Electrical Signaling in a Post-10 Gbit/s World, Part III
Practical Cabling of 25 Gbit/s Signals
by Michael Fogg, Tyco Electronics
Editor’s Note: EN-Genius is proud to present this multi-part series on what lies beyond the 10 Gbit/s barrier for serial networking and interconnect technologies. Written by an eclectic group of leading technologists, this series will discuss the challenges they are facing as higher speeds push semiconductors to their limits and blur the once-tidy boundaries between the chips and the channels they drive. Later installments will discuss technologies, standards, and design techniques being developed to cope with this brave, post-10 Gbit/s world.
Last month, October 2007, Adam Healey taught us what the industry has learned about 10 Gbit/s signaling from the development of high-speed backplanes. In this installment, Tyco Electronics’ Michael Fogg takes us on a tour of the technologies, techniques, and speed bumps we’ll encounter as we coax copper cabling towards handling 25 Gbit/s data rates.
