For medical and industrial applications I believe their main purpose is simply to provide electrical isolation for safety purposes and they are implemented using transformers. They presumably have higher breakdown voltages than the pulse transformers typically used on circuit-board Ethernet interfaces. Quite reasonably, in my opinion at least, they are not marketed to "improve" the digital data being transmitted.
