| 摘 要： | 利用简化的Giles模型在理论上得到了级联环腔箝制掺铒光纤放大器 (EDFA)中在信道数目发生变化时可能发生的剩余信道功率的拍频现象的解释和一般规律 ,并通过数值模拟和实验验证了这一结果。考虑到其对在网络管理方案中广泛采用的调顶技术下可能对系统误码有较大的影响 ,给出了避免这一现象发生的方法

| Abstract: | Analytical expressions, basic rules and physical interpretation of beat phenomena during channel add/drop in cascaded ring-cavity GC-EDFAs are obtained and agree well with experimental results. Measures to depress or avoid this beat phenomena are proposed for systems using tone modulation technique, where this beat phenomena may lead to severe BER degradation. |
