摘要： The invention relates to an amplifier, in particular for a cable or optical network, for downstream and upstream signals that are transmitted in different frequency bands. The amplifier comprises, a first and a second connector, a common amplifier element for downstream and upstream signals, a first and a second downstream-signal filter, and a first and a second upstream-signal filter. An input of the amplifier element is connected to an output of the first downstream-signal filter as well as to an output of the first upstream-signal filter; an output of the amplifier element is connected to an input of the second downstream-signal filter as well as to an input of the second upstream-signal filter; the first connector communicates with the output of the second upstream-signal filter and the input of the first downstream-signal filter; and the second connector communicates with the output of the second downstream-signal filter and the input of the first upstream-signal filter.
