Claim 0:
1. A system comprising:
a) a first device configured to:
i) receive, from a cable television (CATV) node, first downstream CATV RF signals, and convert the first downstream CATV RF signals to downstream optical signals;
ii) receive upstream optical signals, and convert the upstream optical signals to first upstream CATV RF signals;
iii) wherein the downstream optical signals are distributed separately from the upstream optical signals by using at least one of different fiber optic cables or different wavelengths;

b) a first micro distribution system and a second micro distribution system, each of the micro distribution systems being independently operably coupled to the first device and comprising:
i) a micro node configured to:
1) receive the downstream optical signals, directly or indirectly, from the first device, and convert the downstream optical signals to second downstream CATV RF signals;
2) receive second upstream CATV RF signals, and convert the second upstream CATV RF signals to the upstream optical signals received by the first device;

ii) at least one string of taps operably coupled to the micro node and configured to:
1) receive the second downstream CATV RF signals, directly or indirectly, from the micro node;
2) passing the second upstream CATV RF signals, directly or indirectly, to the micro node; and
3) receive a powering signal;
4) wherein each of the at least one string of taps comprises taps and is terminated at an end of the string by a low pass filter (LPF);

iii) wherein, for each of the at least one string of taps:
1) the second downstream CATV RF signals are passed from the micro node along the taps and blocked by the LPF;
2) the second upstream CATV RF signals are passed along the taps to the micro node; and
3) the powering signal is passed along the taps and through the LPF; and

iv) 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.
