1. A datalink tool, comprising:
a first assembly and a second assembly, wherein the second assembly is disposed to move relative to the first assembly;
a space;
a hardwired electrical connection between the first and second assemblies, such that at least part of the hardwired electrical connection is configured to be immersed in an internal fluid contained inside the space; and
a compensator sleeve contributing at least in part to isolation of the internal fluid inside the space from an external fluid residing outside the space;
wherein the compensator sleeve is disposed to expand and relax in response to pressure variations in the external fluid, such that said expansion and relaxation of the compensator sleeve attenuates transfer of said external fluid pressure variations into the internal fluid.
