Cheating with a Cat5 installation?

Hi all
I need to install another access point along a lenth of previously installed
cable. It will be a major problem to fun a seperate cable back to the switch
point, so I was wondering if I can use the unused pair of cables inside the
existing cable to create the new access point. I understand that although
there are 8 cables inside a standard cat5 cable only 4 our used, connected
to pins 1,2,3 &6 if I carefully strip out the other wires and install them
to a new RJ45 socket, and do this at both ends, will that work ?
Thanks
Tony

Given that Cat5 cables are shielded and you'd penetrate the shielding, I
think you'd wreck the cables.

If it's a low transfer rate you need, why not put down some BNC cable
instead? That will take connections in various places.

Thanks for the suggestion, the problem is that I can`t put in any type of
cable without it becoming a major problem, I was wondering if I could just
"carefully" open the outer cove and without cutting the 4 wires that are
already being used make a new connection using the other 4 wires.

5 port Switch ----Cat5--------Cut-----8
wires-------------------------------------Existing PC
4 wires

New PC

Does this make sense ?
Thanks

Yes, it should work OK for 10/100 MBps Ethernet.

Personally, not being an expert, I'd say it's not possible. Have you
considered WiFi instead?

Eh? I've seen lots of Cat5 cable but never any that's shielded.

I have some that appears to have shielding. It's definitely got something
wrapped around under the cover and I use it as a crossover lead.

There's UTP and STP cable, being unshielded and shielded respectively.
Shielded is used sometimes in noisy environments, but UTP is by far the
more common.

I don't think you will have any problems doing this if you are running at
10/100.

The cable is probably not shielded, so you won't have any problems there
either.

Obvioulsy the two "spare" pairs you use will need to be wired to the correct
pins at both ends, so the colour coding will not match the normal
convention, but so long as you know what's going on then not a problem.

I've got many cat 5 runs in my place all of which support two sockets from a
single 4 pair cable, was the quickest, easiest (and cheapest) way of getting
two sockets to each room. Some rooms have 2 x ethernet and some have 1 x
ethernet and 1 x telephone, and one has an ethernet and a wired intercom -
I've not had any crosstalk problems and they all run at 100meg ok.

Just keep the pairs twisted right up to the RJ45 socket, you only want them
parting about 1/4" before the IDC punchdowns.
