Device that allows to regenerate the Duox signal in both directions, isolate sections of the installation, as well as extend distances and terminal capacity. Input and outputs are isolated, against short circuits, load and signal reflections. It has 1 Entrance and 1 Exit. The sections on both sides require their own power set (“filter + source”): the 1-output regenerator amplifies the data, but does not let the power through. Recommended use: extend distances, increase number of terminals, isolate segments of the installation, isolate cable section changes in the same segment. Small in size, they can be installed in electrical registers. They can be screwed directly to the wall.
