As far as I can tell Broadcom, Teranetics/PLX, Solar Flare and Aquantia sells these. Here are the links to ICs: http://www.broadcom.com/products/Physical-Layer/ http://www.teranetics.com/products/10gbase-t http://www.webcitation.org/5jc2TUnO0 http://www.aquantia.com/pdf/AquantiaAQ1002_11172008.pdf

Solarflare is still in business as far as I can tell. Teranetics was acquired by PLX ...

SFP+ transceivers are low cost .. .it's just the Network supplier mark up that makes them expensive to the end-user. 20X OEM price.

Does anyone know what happened to Solarflaire and Teranetics? I worked on 10GBASE-T design 7 years ago and at the time they were the only two start-ups in that space....Kris

I agree... pretty sure Broadcom, Teranetics, and Solarflare all have 10GBASE-T transceivers. Although, the article does mention "integrated", so perhaps they mean a MAC/PHY single chip (which I'm not sure Intel has... I know there's the 82599 but it requires an external XAUI to 10GBASE-T conversion....)

10GBASE-T, even at 40nm, is higher in both wattage and in latency. But it is a lot cheaper. 10GBASE-KR is already selling as a LOM in HP Blade servers.

Doug, I thought the same thing too. I thought 10GBase-T had a lot higher latency due to the massive amount of signal processing needed to essentially perform the impossible. Also, what about the latency of 10GBase-T versus doing 10GB Ethernet over twinax cabling?

Doug: optical link requires E-O-E conversion so the power includes laser, photodiode etc in addition to the electronic portion...still an order of magnitude power for Base-T solution is hard to believe considering the amount of equalization one has to do at 10 Gb/s...Kris

Is this correct? Even at 40nm the 10GBase-T chips will consumer an order of magnitude less power and have dramatically lower costs and latency than the optical SFP+ links, Brown said. I thought SFP+ would always have lower latency and power compared to 10GBASE-T.

I am having hard time believing that Intel is the only company that has 10GBase-T transceiver technology...there was at least 4 guys a while back developing this, I guess some got swallowed in acquisitions but there must be another source. Anyone? Kris
