Spectra7 Microsystems Inc. and Wandtec announced they are collaborating on Spectra7 enabled 100G DSFP, 200G QSFP56 and 400G QSFP-DD Active Copper Cable (ACC) interconnects targeted at major datacenter operators and high-performance computing OEMs. The initial collaboration is for 100Gbps DSFP interconnects. Major China operators including Alibaba, Baidu and Tencent are choosing this standard for higher speed and higher density switch and server connections. 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.
