"Engineers explore life beyond 10 Gbit links
 Designers rally around 25G, but next step still a mystery"
 02/08/2010, 4ページ

 "At three separate industry events last week, engineers said they
  are gearing up to deliver in 2011 chips that can handle serial
  data streams running at 25 Gbits/second to drive next-generation
  100 and 400 Gbit/second networks. But they say it's still a
  mystery how - or if - they can deliver follow-on components for
  the terabit networks today's Internet data centers are already

 "The kinds of jobs required to run today's Web 2.0 services such
  as Google and Facebook can completely overwhelm current 10 Gbit/s
  Ethernet links in the warehouse-sized data centers those companies
  use. Such data centers could use hundreds of 100 Gbit/s Ethernet
  links today, although standards for such networks are still being
  completed. "

 "Facebook is not alone. Google and others have said they will need
  Terabit Ethernet products as early as 2013."

 "Indeed, engineers said the draft specifications for 25 Gbit/second
  serial-deserializers, called serdes unveiled last week at a meeting
  of the Optical Internetworking Forum are essentially based on
  pushing both silicon and board materials to the max. Serdes are
  the basic I/O building blocks out of which virtually all today's
  high-speed chips are built." (関連記事は後述)
 "The 25G serial standard is meant to relieve pressure on
  first-generation 100 Gbit Ethernet products being built today using
  ten lanes of 10 Gbit/s serial links, today's fastest interfaces."
