usb via cat5, whats inside these commercial versions?

Hi there,

I am aware of the instructables of using cat5 cables for usb extension.
It says the max. length is sth like 30 ft / 10 meters.

And I found out these are also commercially available.
usb cat5 up to 40 m / 125 ft

Whats in the housing? Does anyone know?

Is it possible to build on your own sth like that?

you can get quite long with usb hubs for really long maybe set up a complete pc at the other end (pentium 1 board with bootable netcard and onbard usb 1.1)
