Rencently, i have found there is one optical fiber device which could come with PicoScope to expand the transmission distance of USB3.0 up to 100m (330 ft). So i can't wait to share with you. Maybe you are also exploring the same deivce.
I have tried PicoScope 6404D , 5244B and 2207 and all of them do work. Attachment are two pictures,one is how to connect PicoScope to PC via the fiber cable,the other is the schematic diagram of the USB3.0 to fiber converter.
I have get them to work togther the whole day. The downside of the converter i found is that it might be some hot when running.
If you would like to have an idea of the detailed infomation of the fiber , you could click the below link and enter its website.
