"10GBase-T Compliance in Doubt", March 19, 2007, Byte and Switch News Analysis.

"Claims by Ethernet adapter makers that they comply with the new spec for 10-Gbit/s Ethernet over
copper may be premature, warn vendor and standards body sources. And until interoperability tests are
completed at the University of New Hampshire's InterOperability lab in April, no one can really claim to
support the specs, they add."

"Until then, vendors such as Chelsio and Tehuti Networks may want to tone it down where claims of
being "first" to support 10GBase-T are concerned, vendor sources say."

"...to support links up to 50 meters on standard Category 6 copper cabling, and up to 100 meters on
what's called Category 6a,"
"But Chelsio does not support those distances, apparently."

ついでに、
""The first generation of 10GBase-T products are burning 10 to 12 watts of power," says Bob Wheeler of
the Linley Group consultancy. That kind of consumption will be unacceptable to most users, he says."

しばらく様子見が必要そうですね。

"Two adapter vendors, Chelsio and Tehuti Networks, are claiming to have the first 10-Gbit/s Ethernet
cards to work with Category 6 and 7 copper cabling. But it may be awhile before users see real benefits."
