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

What is interesting, now, is that in lieu of copper, aluminium is being
preferred as a conductor, to lower build costs.
