There is provided a cable network device (24) comprising an input (14) connected to a plurality of outputs (16, 16', 16'' and 16'''), wherein the input (14) is connected to each output (16, 16', 16'' and 16''') by first and second electrical communication paths, where downstream signals from the input (14) to each output pass along the first electrical communication path and upstream signals from each output to the input (14) pass along the second electrical communication path, and each second electrical communication path has the same attenuation as the other second electrical communication paths. Input (14) is connected to a diplex filter (26) to separate electrical signals into high and low frequency bands and each output is connected to a second filter (30) to separate out upstream signals. |
