Cat7 for a telephone extension is overkill. More twists mean the length is longer than a cat5. May cause a little more loss on the broadband than using cat5.
I'll get him to use cat5 then. Would there be any speed loss compared to connecting straight from the master socket?
Is he moving the phone or broadband (or both?)
if broadband - cat 5/e will more than suffice as it supports 1gbps
cat6 is basically reinforced cat5e to try and ensure bend radius and ensure the above
cat7 iirc is also individually screened to support 10gps
**edit** you original post says telephone extension so ignore the above
I'm planning on relocating all my AV/Comms to a cupboard under ther stairs.
The installer is going to leave the NTE5 socket where it is and wire an extension, I assyme from the back of the faceplate, to the cupboard. He will use Cat7 cable to wire it up.
Will this be ok given the quality of cable to be used and the relativelty short distance that it'll run?
To be clear, it's not running an ethernet cable. It's a telephone extension using Cat7 cable.
What happens with the filtered faceplate that sits between the NTE5 back box and the faceplate?
I assume he knows what he's doing as he does this for a living and has had no issues before. I just wondered how he does it.
Jeeze, You have said the man does it for a living and you have had no issues with him, can you not just leave him to get on with his job!!
Fair enough but I think that you should leave the man to get on with it without telling him his job or what cables to use. Either that or do it yourself.
If he is any good, which you seem to think he is I'm sure he would be able to answer your questions about what and why he is doing what he is doing and he would probably take exception to being told what cables he should be using because you have checked up on a forum, which is giving you differing opinions.
