Can I use two different in-link ads network?

Hi, guys, I have a question want to ask.
Can I use two different in-link ads network at the same on my blog?
I am using infolinks ads network now, it is good. And I want to try anther one, but I don’t want to move infolinks code, so can I use them both? Will they effort each other?
Thanks!
