I know the newer wires that got strung in my neighborhood are aluminum, and that in home wiring when using aluminum something called Noalox (I think that's a brand name) is used at junctions for the purpose of preventing the oxides you mention. I never would have guessed it was applicable to communications, but I suppose where there's wire, there could be a need.

Be sure to read all the product precautions on the tube of ITT goo before using it. It is not to be used as a personal lubricant unless you're an android.....

No worries, we just hop over the border for a little Pennzoil when the need arises.:D

I was given some of that aluminum stuff wadded in some cellophane wrap to use and it looked like black silicon caulk, but I have no idea what it was. I believe that the dielectric grease prevents not only moisture from contacting the connection, but also the other required ingredient for oxidation; air and the oxygen it contains. And don’t smear half a tube in there. :)
