  • Data communications system that prevents undesired coupling between data stations
    Patent number: 5146357
    Abstract: A data communications transceiver or configuration prevents undesired coupling between data stations by eliminating any connection between the ground path circuits of those data stations and line conductors connecting such stations together. The line conductors can be metallic and are coupled to the data stations by optical couplers. The optical couplers are powered from power sources that are totally separate and independent from any power sources associated with the data stations.
