App note from ON Semiconductors about the need for long cables for high speed Type-C and Type-A connectors. Link here (PDF)
With the increasing requirement for high speed transfer of larger bulk of data, better quality video and power delivery, change over from analog to digital videos, bi−directional transfers, it become essential to use a proper cable that delivers the data correctly between external hard drives and other systems or end products.
The use of Active cable becomes a necessity with increase in cable lengths of more than 5 meters, number of ports and data rates 10 Gbps and above. To match these using passive cables will become expensive with increased weight and thickness.
