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).

摘要： PROBLEM TO BE SOLVED: To provide a single-core bidirectional optical transmission system inexpensively extending a single-core bidirectional optical transmission path. SOLUTION: A plurality of optical signals different in wavelength are multiplexed. Bidirectional transmission is performed between a first optical transmission/reception terminal 10A and a second optical transmission/reception terminal 10B via a single-core bidirectional transmission path 500. First signal light from an optical transmitter (Tx) 200 in the first optical transmission/reception terminal 10A and second signal light to be input to an optical receiver (Rx) 300 in the first optical transmission/reception terminal 10A via the single-core bidirectional transmission path 500 are multiplexed in the same direction using a Red/Blue filter 120 that is an example of an optical multiplexing element, and collectively amplified in an optical amplification part 110 of a single optical amplifier 100 by using the first signal light of a larger signal level as clamp light. The amplified second and first signal light are demultiplexed to the optical receiver (Rx) 300 and the single-core bidirectional transmission path 500, respectively, by a Red/Blue filter 130 that is an example of an optical demultiplexing element.
