JS are you saying:
Ethernet > FMC > optical (10 meters) > FMC > Ethernet > Switch (?) > streamer
Here’s what I have:
Switch > Ethernet > FMC > optical > FMC > Ethernet (0.5”) > streamer (Roon end point)
One of the ports from the switch is then:
Switch [same switch as above] > Ethernet > Roon Nucleus server
Switch is needed in my case for server and streamer, but I’ve also heard on other threads that audiophile switches clean up the signal even more before the FMCs. I’m having the FMCs [essentially last FMC with LPS] clean up the signal after my generic switch and right before my streamer. I haven’t heard of adding a switch after FMC utilization, but perhaps people are? I’ll let more experienced people chime in if such is the case.
