Network Switches

For now:

Router ----> Ethernet cable (copper) ----> opticalModule ---> fiber cable ---> feeding A side SFP module / cage on EtherREGEN ----> Ethernet Cable out of the B-side on EtherREGEN ---> Innuos ZENith MK3 (as Roon Server and endpoint) ---> USB cable out to DAC (MSB Discrete)
If I am using a pair of FMC’s ie. TP Link MC100CM’s at router and then a BJC CAT6 to a single source ie. an Aries streamer, does adding a switch somewhere to the chain make a difference? Or does going fibre with the FMC's already provide enough isolation to cover it.

I only have a single source.
@mikey8811  I was using similar optical isolation with dual opticalModules from Sonore each powered by its own SGC 5V power supply. I replaced the one downstream with the EtherRegen. Kept the opticalModule upstream. This change provided an audible positive SQ difference for me. EtherRegen gives us more than optical isolation. Read the technical details if so inclined:

Having said this, each system is different. You will need to try for yourself if you really want to know for sure.
