Aquantia Gets out of the 10-Gig Gate

Another chip startup is joining the race to provide 10-Gbit/s Ethernet over copper.

Founded early in 2004, Aquantia Corp. isn't officially talking about its funding. But previous reports have noted the company raised $12 million recently from investors including megafoundry Taiwan Semiconductor Manufacturing Company (TSMC) (NYSE: TSM). Venture investors include Lightspeed Venture Partners, Greylock Partners, and Venture Tech Alliance.

Aquantia has an office in Milpitas, Calif., but the company started out homeless, in classic Silicon Valley fashion. "The lobby at the Westin Hotel was great, because they mistook us for guests and gave us free coffee. And we got free wireless," says Bill Woodruff, Aquantia's vice president of marketing.

Aquantia joins a pool of chip startups working on various forms of 10-Gbit/s over copper, including KeyEye Communications Inc., Quake Technologies Inc., SolarFlare Communications Inc., Teranetics Inc., and Vativ Technologies Inc. Of course, heavy hitters Broadcom Corp. (Nasdaq: BRCM), {dirlink 2|39} (Nasdaq: INTC), and Marvell Technology Group Ltd. (Nasdaq: MRVL) are interested, too.

Pings to the competition revealed no details about Aquantia, but it's reasonable to bet that the company's expertise lies in signal conditioning. Electronic signals get distorted by the combination of high speeds and long distances, and engineers have been developing techniques to ensure those signals get received accurately as zeroes and ones.

This isn't necessarily a penny-ante technology; SolarFlare raised $48 million early this year, bringing its funding total to $78 million. (See Solarflare Raises $48M.)

Aquantia CEO Phil Delansayhails from Lightera, which was acquired by Ciena Corp. (Nasdaq: CIEN) in 1999. Chief architect Ramin Farjadwas a founder of another signal-tweaking specialist, Velio Communications, which was acquired in pieces by LSI Logic Corp. (NYSE: LSI) and Rambus Inc. (Nasdaq: RMBS). (See LSI Snares Velio and Rambus Buys Velio's Serial Biz.)

The hottest 10-Gbit/s copper craze is the Institute of Electrical and Electronics Engineers Inc. (IEEE) 802.3an standard, also called 10GBase-T, which members say is on track for ratification in June. Note that this technology is for the LAN -- 100 meter distances -- rather than for long-distance telco uses; nobody's talking about 10-Gbit/s Ethernet to your house yet (sorry).

Another 10-Gbit/s copper standard -- 802.3ak, or CX4 -- has been ratified, but it uses InfiniBand cable and covers a shorter distance. "The gold standard for the LAN is 100 meters," says Bruce Tolley, director of marketing for SolarFlare. (See 10-GigE Copper Heats Up.)

By contrast, 10GBase-T covers 100 meters on augmented Category 6 cable and 55 meters on regular Cat 6, Tolley says. Some 802.3an members were proposing another version to cover even shorter distances, aiming to provide a lower-power option, but "they didn't have enough votes to go to the next stage," Tolley says.
