RE: Square one stuff

Bryan,
Gigabit Ethernet (1000BASE-T) uses all 4 pairs in a Cat5e cable to send the
data so you do need to run a separate cable to each socket from node0
unless you can put a switch somewhere nearer to the places you need
multiple outlets. See this for further details http://en.wikipedia.org/wiki/Gigabit_Ethernet

Cheers

Hi all,

Please be kind to me - I'm new to this. :-[

As I understand it, Cat 5e has four pairs, so could terminate to four
RJ45 sockets. If I only need one or two, can I strip the cover off and
route the other pairs to a nearby location? I can see that this might
raise some issues like separation of the two uncovered pairs, but if
not, it seems that every cable should emerge to a double wall box so
that there is the potential to terminate all four pairs.

An example might be if I wanted to make data available to a bedroom both
sides of a bed. If I could use one cable to route to both sides, I would
still have two sockets each side. Even if I used one pair each side for
voice (I */can/* do that can't I?) it would surely be adequate for most
people?

Perhaps I am missing something, but it just seems a bit . . err,
wasteful to run a separate 8-core cable all the way from N0 just for one
socket. My major refurbishment project currently proposes 36 cables and
I am thinking that it's all getting a bit out of hand! Especially when I
start to think about the money pit that N0 is becoming.
