'''Network isolators''' are installed as part of a wired [[Ethernet]] system as [[galvanic isolation|galvanic isolators]] to reduce the potential for [[electrical injury]] and limit the extent of damage due to [[lightning]] strikes.

Through the applied principle of [[electromagnetic induction]], network data is transmitted across an electrically non-conducting barrier. High frequency [[AC voltage]]s conveying [[Data (computing)|data]] are [[transformer|induced]] across an isolating gap.

The network isolator is a [[passive device]], and functions without any requirement of an external power supply. A functional equivalent to network isolators is Ethernet over a small stretch of [[optical fibre]], using media converters or Ethernet switches/network cards with fiber connections on each end.
