I think the engineers might enjoy this.

This is from 2018 - the submarine cable industry has come a long way since then :-). Channel spacing on marine systems has always been the game. Adding intelligence into branching units (BU's), as well as improvements in amplifier design has been a contributory factor as well. What is interesting, now, is that in lieu of copper, aluminium is being preferred as a conductor, to lower build costs. Mark.
