Fiber or Eithenet

Just to clarify SGC is next to the router in another room.  Looking to pull cable from a switch next to the SGC to my audio room some 50 feet away.  It is that cable I need to put in place.  Thanks for the recommendation.  

Sorry new cable will go from switch next to SMC in a separate room  to audio room connecting a Bricasti M1 with network card.    

That long a run get a quality Media Converter like the Sonore Optical Module. https://www.sonore.us/opticalModule-Deluxe.html

Finisar SFP FTLX1475DFBCL and LC-LC-SM-DX-0S2 Corning Fiber. https://www.amazon.com/Fiber-Patch-Cable-Single-Duplex/dp/B00T89DIQW/ref=asc_df_B00T89DIQW/?tag=hyprod-20&linkCode=df0&hvadid=693418895745&hvpos=&hvnetw=g&hvrand=2785120018893449731&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1026899&hvtargid=pla-353208159507&mcid=de49865fd06b37f29def0e7ae4fca560&th=1

For 50FT run, Linkup cable would be more than adequate for your application. 

@tkrtrb125 - Thanks for the recommendation.  I'm using a Sonore Optical Module today right in front of my DAC.  I guess I'm asking if I should convert to fiber at my switch next to my router, run 50 feet of fiber and convert to ethernet just in front of my DAC or run 50' of ethernet and convert to fiber and then back to ethernet just in front of my DAC. Is there a SQ advantage to one?
