It's a very good question. I believe you have to "push" it through as
you're installing the conduit, assuming that you can't get to the conduit
later.

How do you get it out of the box then?

Umm, you've honestly got me there. I'm off to read up more and also talk to
the guys that install our cable here. The only thing that springs to mind
is the difference between the sometimes quite strenuous efforts used to pull
mains cable when installing, which Cat5e won't take, compared to the
expected relatively gentle pull required to unroll it out of a carefully
wound box.


This is clearly less of an issue in offices where, for example, the
cable is laid under a false floor (as I'm sitting on at the moment) but
more
difficult in a home.

The issue is that Cat5e is quite fine wire and easily damaged. You'll
probably still get a connection but depending on the damage, crosstalk
etc.
result in far lower that 100Mbps that you expect. This is an issue for
high
bandwidth applications like media (video) serving.

Bollocks.

Which bit, the crosstalk/low speed if damaged or video wanting high
bandwidth?

Pulling a cable in the methids you describe will not cause any
problems. Excessive force will damage a cable, but so far all that
you've described are normal installation methods.

I've installed thousands of cat5e cables and had the analyser on most
of them and had the odd wiring error and dodgy termination but never
had a cable fail on any other criteria. Some of them I've not expected
to pass as they have been dodgily installed as temporary measures.

I'm going to have to check through soe of your other posts. I was
under the impression you were reasonably sane.

When I've taken my meds ;-). Seriously, I'll try and dig out some refs. for
you as I've come across this info. on the web often, especially when I was
considering how easy it would have been to cable my 1920s house (bloody hard
without ripping it apart or leaving exposed cables was the answer).
