Quake unveils 'first' PHY IC for SFP+ 10GbE apps

Quake Technologies Inc., a supplier of 10Gbit physical layer ICs, has announced the availability of the QT2035S, said to be the industry's first integrated physical layer IC for all SFP+ 10GbE applications. The advanced signal processing technology in the chip promises to reduce the cost of 10Gbit optics to less than a quarter the price of today's solutions, the company said.

The rapid growth of data-intensive applications and the broad adoption of Gigabit Ethernet have led to a greater demand for 10GbE switch ports, uplinks and server connections. Despite the demand, 10GbE still carries a significant price premium over Gigabit Ethernet. SFP+ pluggable optical modules are increasingly recognized as a technology necessary to bring the cost of 10GbE more in line with that of Gigabit Ethernet.

"Today, the wholesale cost for a typical XFP module for short-reach 10Gbit Ethernet is approximately $350. Using Quake's new QT2035S and SFP+ technology, the cost of a module for this same reach can be reduced to below $100," said Mitch Kahn, Quake's VP of marketing. "At this new price point, 10GbE becomes very compelling for a range of high-volume applications."

By reducing silicon in the optical modules to a minimum and through economies of scale between FibreChannel and Ethernet production volumes, Quake said the cost of SFP+ modules is significantly lower than larger form factors.

In order to facilitate the shift to SFP+, Quake said it has overcome the significant technological challenges associated with signal integrity at 10Gbps. According to the company, these challenges require advanced signal-processing capabilities and the QT2035S is the first silicon device to integrate a standard XAUI-interface 10GbE PHY, with complete SFP+ signal processing support.

"The signal processing problem for SFP+ presents a significant challenge," said Stan Blakey, Quake's director of product architecture. "For SFP+, the PHY must provide equalization not only for various grades of installed-base fiber, but also for circuit board impairments. The programmable Electronic Dispersion Compensation engine in our QT2035S device is the first solution to provide the performance headroom required in SFP+ applications."

"An additional benefit of the EDC performance of the QT2035S is that is allows us to use lower performance transmit optics, such as those for FibreChannel, and run them at 10GbE," continued Kahn. "The EDC engine compensates for the limited transmitter bandwidth; enabling over time a 10GbE short-reach SFP+ module with a cost very close to that of a FibreChannel SFP. At around $50, that's a 10x savings over today's technology."
