1. bidirectional optical amplifier array (VA), its be disposed between first network terminal (OLT) and second network terminal (ONU) and in one direction by optics downstream signal (OSD) by and on opposite direction, pass through by optics stream signal (OSD), it is characterized in thatArrange first branch and assembled unit (D1) in first network terminal (OLT) side,Described first branch and assembled unit (D1) have at least one public terminal (A1) of being used for two signals (OSD and OSU) and have output (A2) that is used for downstream signal (OSD) and the input (A3) that is used for stream signal (OSU) in second network terminal (ONU) side in first network terminal (OLT) sideThe output (A2) that is used for downstream signal (OSD) is connected by the input that is used for downstream signal (OSD) (A4) of unidirectional optical amplifier (E1) with second branch and assembled unit (D2),The output (A5) of the stream signal (OSU) of second branch and assembled unit (D2) is connected by the input that is used for stream signal (OSU) (A3) of transponder (T) with first branch and assembled unit (D1),Second branch and assembled unit (D2) have the public terminal (A6) that is used for two signals (OSD and OSU) in second network terminal (ONU) side, this public terminal (A6) is connected with bi-directional optical amplifier (E2), and the public terminal (A7) that is used for two signals (OSD and OSU) is from this bi-directional optical amplifier (E2) second network terminal (ONU) that leads.
