Yes, any active cable jack will work with your cable modem - providing it receives enough signal.
Note: Depending on how many splitters are installed, some cable jacks will not have as strong of a signal due to how many times it is split to the TV, which results in Speed reduction. If you must split .. Try this plan:
Main cable line goes to splitter, then one cable line is for the cable modem, and the other cable goes to the number of cable boxes in your home. This is done so the signal will not degrade on your cable modem.
