采用分立光器件技术，设计了一种基于四光纤准直器和介质薄膜滤波片的新型可重构光分插复用器，该器件的输入、下路、上路和输出四个端口位于可重构光分插复用器的同一侧。利用 Optisystem 软件，对所设计的ROADM器件的性能及其在联网条件下的误码率和眼图进行了仿真测试。仿真结果显示：该器件的光功率损耗为2 dB，各信道增益基本均衡；联网条件下，在传输距离为75 km、传输速率为2.5 Gb/s的系统中，误码率小于10-9， Q因子大于6，眼图清晰。该器件可以满足城域网中的传输需求。

Applying discrete optical component technology, a novel Reconfigurable Optical Add/Drop Multiplexer (ROADM) based on the four-fiber collimator and thin film filter is designed. Four ports, including input port, drop port, add port and output port, are arranged on the same side of ROADM. Simulations to the designed ROADM, as well as bit error rate and eye diagram in networking, are performed using Optisystem. Simulation results show that the designed ROADM has loss of 2 dB and balanced channel gain. In networking, the bit error rate is less than 10-9 and Q value is more than 6 with clear eye diagrams at speed of 2.5 Gb/s and distance of 75 km, which verifies that the designed ROADM is suitable for the metropolitan area network system.
