1. A data and power communication cable, comprising:
a first connector configured to mate with a corresponding connector of a first device, wherein the first connector is configured to receive a data signal and a power signal from the first device;
a first galvanic-isolating device configured to generate a galvanic-isolated data signal based on the data signal;
a second galvanic-isolating device configured to generate a galvanic-isolated power signal based on the power signal, wherein the second galvanic-isolating device comprises a charge pump configured to charge a shunt capacitor based on the power signal to generate the galvanic-isolated power signal;
a second connector configured to mate with a corresponding connector of a second device, wherein the second connector is configured to provide the galvanic-isolated data signal and the galvanic-isolated power signal to the second device;
a first set of one or more communication mediums configured to route the data signal or the galvanic-isolated data signal from the first connector to the second connector; and
a second set of one or more communication mediums configured to route the power signal or the galvanic-isolated power signal from the first connector to the second connector.
