Quake's PHY Reduces 10 Gigabit Ethernet Costs

\[July 24, 2006\] The QT2035S lays claim to being the industry's first physical layer (PHY) IC for all SFP+ 10 Gigabit Ethernet applications and promises to reduce the cost of 10G optics to less than a quarter the price of currently available devices. It integrates a standard XAUI-interface and 10G Ethernet PHY with complete SFP+ signal processing support. Addressing the equalization needs for various grades of installed fiber and circuit board impairments, the PHY also integrates a programmable electronic dispersion compensation (EDC) engine to provide the performance headroom required in SFP+ applications. An additional benefit of the EDC engine is allowing the use of lower performance transmit optics and running them at 10G. According to the company, the EDC engine compensates for the limited transmitter bandwidth, enabling over time a 10G short-reach SFP+ module with a cost very close to that of a Fibre Channel SFP. The QT2035S will be sampling in August. An evaluation board and SFP+ reference design will also be available at that time. QUAKE TECHNOLOGIES INC., Santa Clara, CA. (408) 727-5800.
