Depending on how good the signals are you will need more or less
filtering and separation circuitry at the ends. I'd just try it with
simple splitters and see if it's OK, if it's not OK then try cleverer
I can vouch for it being fine if you use CT100 cable as the co-ax.
This is very well screened satellite grade cable and recommended for
any form of home antenna and other TV distribution.
Whether cheap TV coax would be OK, I don't know, but I would recommend
against its use anyway, CAT5 or not

Most computer rooms have MILES of the stuff tied together in huge bundles. It
all tends to be under the floor with the power, air con, fire suppression,
fibre cable etc ete .....
There are maximum lengths on each cable run, witch are designed so that the loss
of signal is not so high that you can not read the signal. There are also
issues with maximum propogation delay (speed of electricity to you and I) if the
cables are too long. The rules get more strict as you run your data faster
10Meg 100Meg or 1000Meg
If you are overrunning your cable lengths, then you need to move to fibre, which
has a problem of the speed of light being too slow.
If you are simply doing your house, you are unlikley to run into probelms,
unless you compete with the Queen for best house in the country.

I know there is a speed/distance trade off in copper (over relatively short
distances), but wasn't aware of any such restrictions in fibre until you
get to Gbps linerates.

Wwell I wouldn't care too, since fiber cable is only marginally slower
than line of sight microwave, and is about as good as it gets.
Attenuation tends to be teh problem in cvheap fobre optics, and wave
shape 'smearing' due to different speeds of propagation of varuous colors.
Typically multimode fiber is good for 300meters guaranteed, and typical
monomode can be over 3km. If done properly with high power, a lot more
That is so, but that normally relates to CDMSA on un switched ethernet -
the losses are not so high that overunning on length affects signal
level - its just that the colision detection algorithms break down when
long delays happen.
If you use a switch, that problem doesn't occur, and since switches are
pretty much hub prices today anywy, thats the way to go.
Huh? Not sure what you are driving at there...
Its easy to run over 100Mbps supposed limits (30 meters from memory).
If you run a switch tho experience suggests it doesn't matter.
Not tried gigabit stuiff, so can't comment.
Indeed, of course you can run them parallel to each other. The CAT 5
pairs are designed to reject induced interference as the interference
affects both pairs simultaneously. It's not to say that an extended
run won't affect data throughput though. The terminations need to be
good though, and the twists need to go right up to the connector.
There's bound to be some CAT5 specs out there if you google for them.
I used Cat5e in my home network. I believe this is better quality than
Have a word with the guys in comp.dcom.cabling, I went there a few
weeks ago for some advice and they were superb.
You can run CAT5 virtually anywhere. MRI scanners cause problems, but then they
are like the magnets on cartoons, but for real.
CAT5 cable is twisted in pairs, the external effect on one half of the pair, is
supposed to be equal and opposite to the effect on the other side.
