Thank you for your interest in the Intel® RealSense™ Camera ZR300.
I’m sorry to hear that the cable provided doesn’t seem to be suiting your needs.
The fact is that I haven’t used another cable, so I can’t personally recommend an alternative. Also, you have to take into account that the cables provided are the ones that have been officially tested by Intel, so even if another community member provides a suggestion, there is no guarantee that the device will operate as expected.
If you have any other question or update, don’t hesitate to contact us.
Have a nice day.
Andres is correct in his advice that the provided cable has been specially rated for use with the RealSense camera. Having said that, if you want to take the risk of purchasing a longer cable then the best results with other RealSense camera models has been with a 1 m cable. This is because the camera's signal gets lost over a long cable. The majority of people in the past who used a 2 m cable failed to get the camera to work with it, though there was a couple of cases where people got it working with a more expensive 2 m cable (i.e a high-end, well made one rather than a budget one).
