I am looking for ways to send a digital signal from an underwater (depth up to 250 m) high-resolution videocamera to the surface. I was told that the Ethenet copper wire (Cat5e) would go only about 75 metres, so a "fiber optic IP cable" was suggested. I think I would need the cable, a tranceiver (?) from copper to fibre on one end, and from fiber back to copper on the other end.
I have a few questions:
- would I need any repeaters to strengthen the signal over say 250-300m of the cable length?
- how physically resilient is the cable - can it withstand repeated rolling in and off a winch and immersion in water
- is some kind of armoured cable a solution?
- where would be a good place to look for quotes (I have had problems with getting straight answer so far).
Thanks
