Hello All,
For complicated reasons I have this cable in place. It was installed
20 years ago and is inaccessible except at the ends. Total length is about 20m.I have not found data on it but there is a 268-307-20 which is a single core 75 ohm coax and this one seems to have six of these, plus what looks like smaller (audio type) coaxes.
It looks like a professional video cable.
I need to send ethernet over it.
I know one can run ethernet over a 50 ohm coax using an RJ45 to coax media converter. These are common and cheap. And one could convert 50 ohm to 75 ohm with adapters which presumably just contain a transformer.
But that gives you only 10 megabits/sec. That is only just barely enough for media (video) over ethernet.
How could I get say 50 megabits/sec? Or possibly standard 100mbps?
Any ideas much appreciated.
