cable connections for wired network

I have 3 computers on wired network and have to move one computer to another
room. It would much more convenient to use the existing cable which would
have to be coupled in two places, however I have been told that although
this can be done it is not recommended, and have also been informed that it
would be ok to use couplings. I would like to know if they are ok to use
and what type to use.

Thanks
Alan Burton.
 
I use a coupling on one, non-essential system in my wife's office. So far
(about 6 months) there's been no problem. The coupling is in a location
where it, and the adjacent cabling, aren't likely to be disturbed. It was a
103 foot run and I was too lazy to get a longer cable :)

A trip to BestBuy, or a search on the web could find you a longer cable so
you could eliminate the couplings - they're relatively cheap. Plus, the more
couplings that you add, the more chance for something to go wrong!
 
Any coupling will introduce a small signal loss. Whether, or not, this will
affect your operation can not be determined until you try it. There are
Ethernet testers available that will do the job, but a new 100 foot cable
(or whatever you need) is going to be many magnitudes less expensive than
the tester would cost.

You mean something like this...

Just use the coupler. As long as you aren't approaching a distance of 100
meters (not feet) I wouldn't worry about it.

Many people will say that you get signal loss. This is not technically true.
You add latency to the line which results in more collisions and retransmits
of data packets.

Just like the whole 100 meter limit. I have run 180-200 meters and still had
systems work. They just have very high rates of collisions with other nodes
on the same subnet. Vlan switches help nullify that issue.


With three computers I really would not worry about it and with the
assumption that you don't live in a Trump sized house.

You can always order some longer cables on-line. Try to avoid buying them at
a BestBuy or CompUSA because they will change you WAY too much for a simple
patch cable. Or, if you are feeling like an adventure, you can make your own
cable. Check out www.geeks.com for cheap kits to make net cables.
