摘要： A bidirectional optical amplifier (1) is arranged to be passed through in one direction by a downstream optical signal (SDS) and in an opposite direction by an upstream optical signal (SUS), and comprises: a first optical circulator (2) having three ports, a first port of the first optical circulator defining a first connector (8) at one end of the bidirectional optical amplifier, a second optical circulator (3) having three ports, a first port of the second optical circulator defining a second connector (9) at an opposite end of the bidirectional optical amplifier, a downstream unidirectional optical amplifier (4) connected between a second port of the first optical circulator and a second port of the second optical circulator so as to define a downstream amplification path (5) for the downstream optical signal, and an upstream unidirectional optical amplifier (6) connected between a third port of the first optical circulator and a third port of the second optical circulator so as to define an upstream amplification path (7) for the upstream optical signal. The bidirectional optical amplifier (1) further comprises a waveband separator (10) connected between the second port of the first optical circulator (2) and an input of the downstream unidirectional optical amplifier (4).
