utp cable length

I have been reading in a network+ book about network cabling. I am
relatively new to this subject and had understood that cat 5 utp cable
was limited to 100-meter runs between switches or switch-to-
workstation. With no explanation, the book has a table describing utp
cable runs in the following manner:

cross connects to telecommunications closet: 800 m (voice
specification)
cross connects to equipment room: 300 m
equipment room to telecommunications closet: 500 m

Can someone who really understands network cabling verify for me that
this means that you can reasonably have 800-meter cable runs with
regular utp cable (not meaning cat 6 or 7)? What then happens to the
100-meter limit? Thanks for any help explaining this.

Hi speed digital is very different than what voice demands.

I've worked with UTP Cat5 quite a bit, the limit for data is supposed to
be 100 meters. I've gone way beyond that several time, not a problem
that I've experienced. When I get a 1000 foot roll, I sometimes will
connect the beginning and the end between a couple of computers. So far,
it works. Maybe it's not as fast as a 50 foot run, but hardly noticeable
difference. There's a ton of information on Google, but I'm not a big
believer in stated statistics unless there's something to back it up.
