Abstract: A contactless data link for connecting a first high speed network to a second high speed network that is rotatable relative to the first high speed network. The links includes a first data processor connected to the first network, and a second data processor connected to the second network. The link also includes a plurality of capacitive data links connected between the first data processor and the second data processor. Each capacitive data link comprises a transmitter amplifier, a capacitive coupler, and at least one receiver amplifier. For communication with the networks, each data processor comprises a physical layer network interface connected to one of the networks. An encoder may be provided for encoding the networks signals into signals, which may be transferred over the contactless data links, while a decoder may be provided for decoding the signals from the networks into signals for the network.
