opto couplers will achieve galvanic isolation but will not block HF noise on the signal lines. For that you need Ethernet filters (expensive) or you can try ferrite clamps (very cheap). The big problem is that in signal terms there is not much difference between HF noise and the Ethernet signal, especially at higher transmission rates. The frequencies can overlap, but the amplitudes are very different (normally!).- so filtering is not straightforward. 10 base-t is easier to filter than 100/1000?
