Adaptive optical signal-to-noise ratio recovery for long-distance optical fiber transmission [PDF]
arXivIn long-distance fiber optic transmission, the optic fiber link and erbium-doped fiber amplifiers can introduce excessive noise, which reduces the optical signal-to-noise ratio (OSNR). The narrow-band optical filters can be used to eliminate noise and thereby improve OSNR.

Guangtongxin yanjiu, 2019 基于信号功率非线性变换,结合神经网络,文章提出了一种利用深度神经网络（DNN）实现光信噪比（OSNR）监测的方法。通过对信号功率、信号2次方、4次方和8次方运算后对应的快速傅里叶变换（FFT）后的幅度获取信号与OSNR相关特征量,并利用DNN提取相关特征量以实现OSNR监测。仿真结果表明,针对28 Gbaud偏振复用（PDM）正交相移键控（QPSK）、PDM-8相移键控（PSK）、PDM-8正交振幅调制（QAM）和PDM-16QAM信号相干光通信系统,对应的背靠背OSNR监测平均标准误差分别为0.10 ...

Guangtongxin yanjiu, 2014 介绍了评估100Gbit/s线路侧光收发模块性能的两个指标:接收机OSNR（光信噪比）容限和Pre-FEC（纠错前）对应模块最大误码率的OSNR值。前者用于评估光模块硬件和软件算法的总体性能,后者用于评估光模块关闭软件算法后的性能。给出了测试框图,采用积分法进行测试,需要对测试结果进行校准。该测试方法对其他线路侧光模块的OSNR测试有一定的借鉴作用。
