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.

Sure you could do that. But then you’d just get a video stream from… somewhere. You want to know where exactly you are and to be able to move around so you can investigate the interesting bits. Which means you need to get electrical power down there as well and some method of propulsion. This means we need a rather large device at the end of the cable.
