Hi,
for a shoot I have to tether a Canon 5Ds via an USB3 Cable. I need approximately 5 meter length.
Hi Johannes,
USB2 is known to work up to 5 metres (as it should), and Repeaters of 5 or 10m are available (can even be daisy-chained for longer lengths). But USB3 cables of length are harder to find. The practical maximum length for USB3 with copper cables is apparently 3 metres, unless special large diameter materials is used.
According to
Wikipedia:
Unlike previous standards, the USB 3.0 standard does not directly specify a maximum cable length, requiring only that all cables meet an electrical specification: for copper cabling with AWG 26 wires, the maximum practical length is 3 meters (9.8 ft)
However,
here is one of 5m I just found by searching, but I do not know how reliable USB3 is at these lengths. Construction quality and materials used will make or break the usability such a long cable.
This might be more reliable (less Radio Frequency Interference), but it uses the USB2 protocol for the data link over optical fiber, so it's probably slower. And the plugs get hot, they say.
Cheers,
Bart
