    Is there any major problems that can come up with splitting a DMX line and is the signal strength effected?

    Not if you use an opto splitter. Electronically splitting it by making a y or t cable is non-adviseable: 1/2 impedance, reflections, etc. - remember it is RS485.

    Use one of these

    Don't just make a cable to do it. While you can trick it into working, I would never recommend it for anything show critical (like, say, your lighting control system).

    Provided you use an opto-splitter, and not a Y-cable or two-fer, no problems at all.
