1. An input/output (I/O) system comprising: a first communicative component; a second communicative component, wherein at least one of the first and the second communicative components includes a device that is superconducting below a critical temperature; and a communicative connection that communicatively couples the first and the second communicative components, the communicative connection including a plurality of printed circuit board (PCB) based stages including a first stage and at least one additional stage communicatively coupled in series with the first stage between the first and the second communicative components, at least one of the first stage and the at least one additional stage including a continuous circuitous conductive trace carried by at least one PCB and a dissipative metal communicatively coupled to the continuous circuitous conductive trace to at least partially dissipate energy carried thereby.
