Commscope cable is one manufactuer that has been used:

Most if not all will be 5-1000Mhz. This includes the network Coax as well.

Also the splitters vary from the many suppliers to the cable industry over the years. But many will range from 5-1000Mhz some will range from 5-750Mhz The newer ones:

The main issue will be the Amplifiers as most will be up to 750Mhz but again they will vary accross the country as will the upstream band this can be anything from 5-50mhz,5-40Mhz, 5-65Mhz.

But once the analogue is gone there is plenty of bandwidth the play with.
