Abstract
The invention provides an apparatus, system and method for distributing passively a coaxial based CATV RF signal over unshielded twisted-pair cables. The distribution of the coaxial based CATV RF signal involves distributing the signal into a group of output signals. The output signals are then coupled to unshielded twisted-pair cables. If the unshielded twisted-pair cable is detached, the output signal is terminated through a resistor. Thus, a coaxial based CATV RF signal can be distributed to many unshielded twisted-pair cables with any unused output signals being properly terminated.
