摘要

我们实验研究了在50GHz网格中传输Nch×100G CP-DQPSK信道(Nch从3到71)的多跨度无补偿相干光学系统中的非线性影响。与解析模型吻合较好，证实了Nch干扰的逐渐增长。对网络设计的影响进行了评估。

Investigation of the dependence of non-linear interference on the number of WDM channels in coherent optical networks

We experimentally investigate nonlinearity impact in a multi-span uncompensated coherent optical system, transmitting, in the 50GHz grid, N_ch×100G CP-DQPSK channels, varying N_ch from 3 to 71. A good agreement was found with an analytical model, confirming the progressive growth of interference with N_ch. Impacts on network design are evaluated.
