Spectra7 Microsystems Inc., a provider of high-performance analog semiconductor products for broadband connectivity markets, and Wandtec, an interconnect technology supplier with operations in both the US and China, announced that the companies are collaborating on delivering Spectra7-enabled 100G DSFP, 200G QSFP56 and 400G QSFP-DD Active Copper Cable (ACC) interconnects aimed at major data center operators and high-performance computing OEMs.

"Spectra7 has created a compelling solution to address the dramatically increasing power and cost of data center interconnects," commented Xin Wu, CEO at Wandtec.

Wu added, "We are seeing significant interest from our customers for ACCs with Spectra7 technology and are pleased to be partnered to deliver unprecedented solutions for low power, low latency and extended reach. In combination with our innovative WDTCDR Twinax cable and patent pending crosstalk noise mitigation technology, we are able to extend 56G PAM4 based copper interconnects to lengths of 10m while being compliant to the IEEE 802.3cd standard."

The initial collaboration between the partners is for 100Gbps DSFP interconnects. The companies note that major operators in China including Alibaba, Baidu and Tencent are choosing this standard for higher speed and higher density switch and server connections.

Per Spectra7:

The DSFP standard using 56G PAM4 signaling enables a 4x increase in bandwidth over currently deployed SFP28 interconnects but the higher data rate limits the interconnect length that can be served by low-cost direct-attach copper (DAC) passive cables. Spectra7's GaugeChanger silicon enables ACC cables up to three times the reach of passive DSFP copper cables.

"Wandtec is an up-and-coming innovative technology leader in data center interconnects," concluded Spectra7 CEO Raouf Halim. "Partnering with them is significant and will accelerate adoption of our technology in this rapidly growing market."
