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.

It’s already done, with a big robot attached to that fiber optic. A 4km long endoscopic probe wouldn’t be very practical.
Eg: [https://nautiluslive.org/](https://nautiluslive.org/) (you can watch them explore live during expeditions)
edit: ok i’m cheating, that fiber optic transmit data.
