40G QSFP+ high speed cable (DAC) adopts copper cable as transmission medium, which has two kinds of passive and active. The 40G QSFP+ passive high-speed cable does not need power supply, and its power consumption is low, but the transmission distance is also short; the transmission distance of 40G QSFP+ active high-speed cable is longer. According to the different connectors at both ends of copper...
