Using Optical Network Port on a Lumin U2

goleksiak  Thanks for the Tip on the Lumin site this will help !!!

I take it any fiber optic cable will do. It’s not susceptible to emi and rfi. I wouldn’t go crazy there. It’s a great option to have in a streamer. 

The Lumin website has links for SPF modules and fiber cables: https://www.luminmusic.com/support-fibre.html

OK thanks for taking the time to respond.

I will do some checking

Honestly I haven’t experimented much outside of fiber optic converters. I got the LinkUp Ethernet and whatever the generic fiber I found….my order…

Can’t tell you anything about fiber optic cables but that LinkUp Ethernet cable is really nice  

Any recommendations on the long cable for option 2?

There are a lot of options for ethernet cable but I have not seen a lot of options for fiber optic cable.

@efoo option 1 is an easiest to test - get the converters on Amazon. If you don’t like the results, return them. Your option 2 is similar to what @ozzy uses with his Lumin and we just chatted about it here - he uses EtherREGEN to output fiber optic. 
If you end up using fiber optic, get a long cable and keep all the switches, routers, converters etc as far away from the component rack as you can.
