Why can’t we explore the bottom of oceans using fiber optic camera

Question

I understand bottom of oceans have huge pressure differentials and lack of light.
However I don’t see why we can’t use two fiber optic cables (one for light one for camera) to explore the bottom of the ocean. When I say fiber optics for camera I mean the slender cameras they use during surgeries.
I’m sure these strands of plastic/glass can handle way more pressure than human body or metal submersibles.

This idea is not scalable. The bottom of the oceans is so enormously gigantic, unimaginably huge, that you could spend a budget of a rich country on mapping with optic cameras every year just to progress a tiny fraction.
