Abstract
A bidirectional optical amplifier () 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 () having three ports, a first port of the first optical circulator defining a first connector () at one end of the bidirectional optical amplifier, a second optical circulator () having three ports, a first port of the second optical circulator defining a second connector () at an opposite end of the bidirectional optical amplifier, a downstream unidirectional optical amplifier () 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 () for the downstream optical signal, and an upstream unidirectional optical amplifier () 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 () for the upstream optical signal. The bidirectional optical amplifier () further comprises a waveband separator () connected between the second port of the first optical circulator () and an input of the downstream unidirectional optical amplifier ().
