are underwater routers a thing?

Surprisingly it is power that primarily limits repeater count in undersea spans.

Ie, most available power is going to be eaten up budget wise by the repeaters, leaving none for routers.

It’s not terribly clear that a router would substantially benefit things that a ROADM could not also accomplish, and those do exist in undersea systems.

As routers decrease in power and coalesce with silicon photonics, this may change.

The route kind of made it look like it was completely at sea, but it would kind of make sense to leave them at sea if you could put a router there.
