Generally, according to the construction difference, the DAC cables can be classified into two types: passive DAC cable and active DAC cable.
Passive DAC cables have no electrical components built into the cable assembly. Hence, it has the minimal power consumption of no more than 0.15w and generally for short reach up to 7m.
Active DAC cables have signal amplification and equalization built into the cable assembly. Therefore, it allows a little longer transmission distance up to 15m and ensures better transmission quality. whereas it has a higher price and consumes more power around 0.5-1w.
