Abstract
In one embodiment, a system includes a CATV node, a first device, and at least one micro distribution system. The CATV node transmits CATV RF signals to the first device, which converts the RF signals to optical signals. Each micro distribution system includes a micro node receiving the optical signals from the first device and converting the optical signals to RF signals. Each micro distribution system further includes at least two strings of taps independently coupled to the micro node and receiving the RF signals from the micro node. Each string of taps is terminated at an end by a low pass filter (LPF). For each string of taps, the received RF signals are passed from the micro node along the taps and blocked by the LPF, while a powering signal is passed along the taps and through the LPF.
