Teranetics intros dual-port 10 Gigabit copper PHY

Aug. 6, 2008
August 6, 2008 -- The second generation TN2022 PHY doubles the port density of switch and network interface cards (NIC), as compared to the first generation of the company's copper 10GBASE-T PHYs.

August 6, 2008 -- Teranetics, a provider of high performance Ethernet silicon, has introduced its dual-port 10GBASE-T PHY IC. A second generation PHY, the TN2022 doubles the port density of switch and network interface cards (NIC), as compared to the first generation of the company's copper 10GBASE-T PHYs. With the smallest form factor available and a low power profile, the TN2022 enables switch manufacturers to design as many as 48 RJ-45 ports into a single rack unit, according to the company.

Typically, 48 ports is the highest density available for standalone 1 Gigabit Ethernet switches in one rack unit. Because the TN2022 supports development of new 10 Gigabit products with the same port count, original equipment manufacturers (OEMs) can design systems that deliver 10x more bandwidth at nearly one-third the cost per Gigabit of bandwidth, maintains Teranetics. At this density and price level, the company says that 10 Gigabit Ethernet becomes a viable for data center managers who require bandwidth upgrades in addition to a fabric for unifying multiple networks in the data center.

"By looking at the underlying needs of OEMs and their data center customers, Teranetics continues to design technology that encourages mass adoption of 10 Gigabit Ethernet," comments Kamal Dalmia, vice president of marketing at Teranetics. "With this new generation product, our OEM customers can fulfill the data center manager's desire to use RJ-45 for the vast majority of 10G connections in the data center using their current wiring and infrastructure."

Teranetics' first generation 10GBASE-T PHY has been adopted by OEMs such as Extreme Networks and Mellanox. The second generation TN2022 PHY consumes 6 watts per port and nearly halves the power consumption compared to the first generation PHYs, while operating at cable lengths exceeding 100 meters. In addition, the TN2022 features multi-rate capabilities, enabling use with RJ-45 Ethernet connectors and making it backward compatible with existing 1 Gigabit and 100 Megabit network gear.

"As a leading provider of 10G switches to the enterprise and service provider segments, Extreme understands that switch density and power consumption are critical to the development of attractive solutions," comments Douglas Murray, vice president and general manager at Extreme Networks. "The Teranetics TN2022 advances the technology while establishing a strong foundation for 10GBASE-T architectures."

The TN2022 dual-port 10GBASE-T PHY transceiver is now available in sample quantities.
