OSNR and nonlinear noise power estimation for optical fiber communication systems using LSTM based deep learning technique.

Optics Express, 2018
The optical signal-to-noise ratio (OSNR) and fiber nonlinearity are critical factors in evaluating the performance of high-speed optical fiber communication systems. Recently, several deep learning based methods have been put forward to monitor OSNR of a

An unsupervised coherent receiver digital signal processing algorithm based on spectral clustering with no data preamble

IET Optoelectronics, Volume 18, Issue 5, Page 131-139, October 2024.
1. The data‐free guided coherent reception DSP algorithm proposed based on spectral clustering can effectively suppress a variety of physical damage and increase the system’s OSNR tolerance. 2. When the bit error rate is 1.9E‐2, the spectral clustering‐based data‐agnostic DSP solution extends the maximum transmission distance of a 14GBaud PM‐16QAM ...

光环形网的光信噪比分析与系统设计

Guangtongxin yanjiu, 2005
文章指出光环形网的设计中必须考虑最长环路保护时的光信噪比（OSNR）计算问题。导出了光分插复用/光交叉连接（OADM/OXC）节点级联的OSNR的计算公式。最后针对链路发生故障点不同的同一业务波长配置的保护倒换情况进行了OSNR的分析,给出了环路保护倒换情况下的OSNR最低条件的模型,并依据此模型建立了光环形网工程设计方法,简化了工程设计中OSNR验证的计算量。

Dynamic Optical Amplifiers Enable Distributed Equalization in Optical Transmission Systems

IEEE Photonics Journal
In this paper, we design and simulated a novel dynamic gain flattening filter (DGFF) module based on polarization-insensitive liquid crystal on silicon (PI-LCoS). The DGFF module measures 26*10.5 mm in size and integrates four DGFFs.
