Room Nucleus One USB port out to fiber converter to Ethernet DAV?

 

Does anybody know if I will be able to connect my DAC, which as currently configured, does not accept USB streaming, to the Nucleus One USB port using one of these::

“StarTech.com USB to Fiber Optic Converter - Open SFP - 1000BASE-SX/LX - Windows/Mac/Linux - USB 3.0 Ethernet Adapter”?  
I have good SFPs and the appropriate Corning Fiber.

I ask because I’d like to get my DAC off my LAN switch.  (The Nucleus and my esro 7 pro router, which is the gateway for WiFi in the home and several other Roon  endpoints, are on that switch.)

If the USB to Fiber converter route works from the Nucleus’ point of view, i can run the fiber to a Fiber to Ethernet converter and then Ethernet cable into my DAC. But will there be a breakdown in communication between the DAC looking for Ethernet protocols and the Nucleus sending out via USB 3.0 protocols?(I’m hoping that is exactly what the StarTech USB to Fiber converter plus the SFP is designed to handle, but just looking for guidance from anyone who knows.
Thanks!

Oh, and is it possible to edit a Post’s title? I’d like to fix that “DAV”!

@erik_squires thanks  

my DAC is integrated into my NAD M33.  It’s a pretty sophisticated DAC with the ESS 9028 Sabre DAC chip.  I do not have the NAD module which would allow for a USB streaming connection.  So the best hardwired connection is ethernet.  That’s what I use currently. 
I was just wondering if that USB/fiber converter that I referred to in my original post would work so I could see what the effect if any of connecting to the room through it’s USB port. I’d use the iFI power X to power the fiber to Ethernet converter that would feed the DAC   That (and the M33) would be connected to an AQ powerquest 505.  (The USB-fiber converter runs off the USB power, no additional power source needed.) the Roon nucleus, the router, cable modem and switch are all on a separate Furman PST-8. 

i’m pretty sure that the net effect of converting back to ethernet in the first place means I’m gonna lose the higher frequency and 32-bit depth that the USB port seems to offer, but  I’m still interested to see if it’s any improvement in sound quality or reduction and noise over what I’m doing now, (which I must say seems to have a very low noise floor). 

thanks!

Thanks again. @erik_squires . What you’ve described (Ethernet/fiber/ethernet) is what I’m doing currently. Just wondering about getting the M33 off the switch.

Probably not doable. Or not advisable.
