Hi Andy,

With regard to your plan of doubling up on runs *IF* you have enough
cable.

At around 10p per metre, CAT5 cable is dirt cheap. The expensive part
is
terminating the cable at around ?2 per patch panel port and around ?5
per
CAT5 socket. If you fit modular sockets then you can populate just one
of
the sockets and fit a blank over the other for a few pence and fit the
socket later when you have a bit more money. By not fitting half a
dozen
sockets you have saved enough money to buy another box of CAT5. Always
terminate ALL the cables on the patch panel so that the numbering is
logical
and you dont have to disturb the patch panel afterwards.

It is false economy to only run a single cable as adding a second at a
later
date involes as much work as the initial cable did whereas running two
cables adds a few seconds to the instalation time for the cable run. If
anything, miss out a couple of rooms where you will not need CAT5 in
the
first instance. That way, when you come to do your second lot of cable
runs
you are running new runs to just a couple of rooms rather than
repeating
what you have already done.

With regard to CAT5 longevity... many companies are only just
installing
their first CAT5 networks. When CAT5 first came out is was used for
10BaseT,
or 100BaseT over 4 pairs. Now 10/100BaseT runs over 2 pairs and the
same
cabling infrastructure is being used for Gigabit ethernet, something
which
just a few years ago, everyone was saying would need optical fibre.
Imagine
how the people who paid a fortune for fibre must feel knowing that they
can
now use their existing CAT5 cable :-)

I may double up the
runs, but I'm on a tight budget for the cabling.  If there's enough in
the
reels, I'll double up.  The plan is for 610m CAT5, and 100m
coax.  A run
>from
substantially less.  I shall do as many runs as I can with that
cable.  I
can always do more at a later date.

I know I shall be doing more cabling at some point, but how much life
does CAT5 have.  Could we be using something else in 5 years?

Cheers,
Andy
