Any gel-core direct burial cable can handle long-term shallow water
immersion. Steve is correct: the fiber in many manholes are underwater
until the next time someone needs to climb down and make a new splice.
I once asked a dark fiber provider to splice from a particular manhole
and they had to send someone out to look because it had somehow fallen
off their map. When they popped the cover to look, the vault was
completely inundated. Hadn't caused them the slightest difficulty.

Submarine cable is needed for deeper water (higher pressures) with
more armor against damage since it's just laying on the seafloor
exposed to everything that happens by.
