After testing the Acer WMR ( windows mixed reality , but it's just a VR headset , confusing name ), we received at work, I was quite impressed of the improvement from the O.R. and Vive, that I have also tested at work.
I chose the Samsung WMR because it solves all the problem from the Acer :
I try to extend the cables, right now I got a UGreen HMDI 2m cable extender that works great. For extending USB 3.0 it is more tricking. I try a normal UGreen Usb 3.0 3m cable extender, but the headset erratically disconnect. I tried a no-brand chinese active Usb 3.0 5m cable, but I think it's a scam and it's not working.
After some research online, I ordered a MonoPrice one, that seems to work with OR and Vive.
