Worth knowing:Show more

Elimination of interference:
The use of isolators in data lines eliminates the effects of interference to which the PC is otherwise subjected through its data cables (ground loops, antenna effects, potential differences), remote lightning strikes).

Electrical isolators are not to be confused with surge protectors that are often incorrectly marketed for the same purpose: Surge protectors have no effect on equalizing currents that exist between the connected devices due to the potential differences, and they cannot prevent damage to interface components by such currents.
