Hi all, I’m trying to run a Ethernet cable to my home office in a house built in the 60s. This connection is unlabeled and I’m not sure what it is. Can I somehow replace it with an Ethernet cable? I’m new to all of this and did some poking around in the sub but I’m not really sure what I’m looking at or what I’m in for. I don’t have any coaxial cables that I can utilize (unless they are hidden behind a wall? Any easy way to find those?). Thank you.
The term you are looking for for this wiring is “ewire”. In this case, it looks like 6 pair of daisy chained ewire.
It’s slightly twisted, but not quite up to being called CAT 3. Almost certainly nailed down along it’s pathway, and unsuitable as pull wire for anything more modern.
You could throw tone over a pair, then selectively snip/reconnect at each outlet to map the physical route… but again, it’s unlikely that will serve a purpose these days.
Because of the daisy chain, using a paired copper networking medium like DSL or G.Hn for these runs will not result in decent reliable performance either (at least without a lot of work turning them into home runs).
Best bet is to put the wall plate on, tie it into your VOIP line or home intercom at the demarc, and run fresh copper (or fiber where appropriate) to each room.
