Internet Cable Speed

Can I run the high speed internet cable in the same conduit/pipe as the cable TV line?

We have a high speed cable line running from the telephone pole underground to our house. We want to get cable TV, but the cable TV line stops at the telephone pole, so we're going to have to run the cable TV line underground ourselves. We know there is enough room in the existing underground conduit to house both the high speed line and the cable TV line. Can we run both together in the same conduit, or will there be interference and problems as a result?

1. No problem at all. Go right ahead.
2. It shouldn't be a problem. I'm a contractor and we do it regularly.
3. Yes you can. Cable tv is a "no voltage" line. If you have regular phone service with dsl or even fios(fiber), its not a problem. There's no 'cross talk' between the lines. Make sure there's no a/c in the same conduit, for safety and code.
