1. A system comprising:
a first device configured to receive CATV RF signals from a CATV node and convert the CATV RF signals to optical signals for distribution via fiber optic cable; and
a first micro distribution system and a second micro distribution system, each of the micro distribution systems being independently coupled to the first device and comprising:
a micro node configured to receive the optical signals from the first device and convert the optical signals to RF signals; and
at least one string of taps independently coupled to the micro node and configured to receive the RF signals from the micro node and to receive a powering signal, each of the at least one string of taps comprising taps terminated at an end of the string by a low pass filter (LPF);
wherein for each of the at least one string of taps, the received RF signals are passed from the micro node along the taps and blocked by the LPF, and the powering signal is passed along the taps and through the LPF; and
wherein the LPF of one of the strings of taps of the at least one string of taps of the first micro distribution system passes the powering signal to the second micro distribution system.
