초록정보

In this thesis, we proposed and demonstrated a new bidirectional add/drop amplifier (BADA) module using an N x N arrayed-waveguide grating (AWG) multiplexer. The crosstalk and relative intensity noise (RIN) are suppressed by asymmetric structure of the add/drop amplifier module. It does not require the optical band pass filter to suppress relative intensity noise. A two-fiber bidirectional self-healing ring network (BSHR/2) with four nodes is implemented from the bidirectional add/drop amplifiers. The distance between two adjacent nodes is 40 km, and the add/drop channels are assigned to satisfy the full-mesh connectivity. In normal state, the length of the longest path is 160 km and no power penalties are observed after transmission. If there exists network failure, switch-control circuits detect the fault and change the state of the ring from normal state to protection state. In the protection state, the longest path is 240 km and the measured maximum power penalties after transmission is less than 1 dB. When the fault is repaired, the repaired link forms another ring. We used this feature to detect the repair of the fault and the network is retrieved to normal state. Switching time from normal state to protection state or vice versa is smaller than 15 ms and the transient due to switching for protection/retrieve does not give rise to any power penalty to surviving channels.
