Abstract
In one embodiment, a system includes a first device that receives, from a cable television (CATV) node, first downstream and upstream CATV RF signals and converts them to downstream and upstream optical signals. The first device distributes the downstream and upstream optical signals separately from each other by using different fiber optic cables or different wavelengths. The system further includes at least one micro distribution system, each comprising a micro node and at least one string of taps. The micro node receives the downstream and upstream optical signals from the first device and converts them to second downstream and upstream CATV RF signals. For each string of taps, the received second downstream and upstream CATV RF signals are passed from the micro node along the taps and blocked by a low pass filter (LPF), and the powering signal is passed along the taps and through the LPF.
