　"Quellan specializes in analog components that improve the performance and functionality of electronic equipment.
　 By removing channel impairments and interference noise, channel performance is dramatically improved across
　 multiple market segments, and end user products are greatly enhanced."

　"To serve next generation Data Center's complex server clusters, Quellan has discovered interconnect issues are
　 critical. By inserting its analog ICs inside cabling interconnects, Quellan is able to achieve unsurpassed improvements
　 in reach, power consumption, latency, gauge size and airflow of tomorrow’s Data Centers. This new ability transforms
　 passive, cabling to intelligent “roadways” that yield lower operating expenses and capital expenditures for the expanding
　 Data Center."

"New Chip Turbocharges Copper Cabling", CIO Magazine, Sep 26, 2006

　"A small chip mounted in the plug housing could enable copper high-speed data cables to be thinner, lighter, and
　 run further, its inventor has claimed."

　"The scheme requires a chip at each end, mounted inside the plug. The chips work by adaptively tuning to
　 the expected signal, and then calculating and subtracting the coupled noise -- in effect, they learn the cable's
　 characteristics and alter the signal to suit them"
