Ethernet switch

but most such converters are not as effective in practice as in theory due to the noise generated by the circuitry doing the conversion back to digital. Installed after an optical-digital converter, the only noise a switch will have to mitigate is the noise generated by the converter circuitry of course.

That’s not true at all.

While it’s true that any Ethernet Switch with a long unshielded Ethernet cable is likely to pick up EMI/RFI, and so should be close to the DAC with a short Ethernet cable. However, virtually any Media Converter, with a proper low-noise Power Supply, and any normal to-specification optical SFP - CISPR 22/FCC Part 15 compliance (look it up) - close to the DAC, with a short unshielded Ethernet Cable, will be the least EMI/RFI polluting solution, period.
