研究了由低掺杂浓度的分布式掺铒光纤级联传输系统中,多个暗孤子组成的暗孤子链的传输特性,结果表明:在分布放大传输中,奇或偶数个暗孤子组成的暗孤子链的传输特性存在较大的差异。其中奇数个暗孤子组成的暗孤子链的传输稳定性较好，而偶数个暗孤子组成暗孤子链在传输过程中存在明显的由暗孤子相互作用引起的孤子自频主漂移和孤子变形。

The properties of dark soliton train in distributed amplification and transmission system are studied. The results show: in distributed amplification transmission system, the properties of dark soliton cascaded by odd and even number dark solitons are different, train transmission of dark soliton train cascaded by odd number dark solitons is stability, but train transmission of dark soliton train cascaded by even number dark solitons is instability, there are apparent soliton self-frequency shift and defor...
