Black Box 4kV 10/100 Data IsolatorProtect your network infrastructure with the Black Box 4kV 10 100 Data Isolator, a compact, plugandplay device designed to shield equipment from damaging ground loops and surge events while preserving highspeed data transmission. When two networked devices sit on different ground potentials, unexpected voltage differences can create ground loops that inject disruptive currents into copper Ethernet links. This data isolator acts as a robust galvanic
