[time-nuts] USB over optical fiber

[Scott McGrath]

Its not so much the noise from the interface its the USB device itself i’d worry about as USB 3.0 generates RF signals up to 3 GHz.   And also has fairly strong signals in the 2.4 GHz ISM band.

I suppose this is vaguely time-nutty. 😊

I have an application where I need to take USB into an EMC faraday cage.
I see a number of optical fiber implementations available, and the prices ($200-300) are acceptable, but I’m worried about noise that the downstream end may cause, since it will need to be inside the cage.

Does anyone have experience with these?  Ones to stay away from?
