Abstract

The following work presents the incidence of linear and non-linear phenomena in digital fiber optic communications through the implementation of a graphical user interface (GUI) designed in the Python multiparadigm programming environment, where the linear attenuation and dispersion phenomena are evaluated. modal considering the group velocity dispersion (GVD) and the third order dispersion (TOD), together with the non-linear phenomenon of phase self-modulation SPM. The methodology consists of selecting a single-mode fiber optic link under the G.652 standard and varying the operating conditions of the communication system based on a Mach-Zehnder (MZM) transmitter and a signal modulated by digital amplitude modulation OOK. The results show the dependence of the linear and non-linear effects in the transmission as a function of the temporal width of the input Gaussian pulse and the wavelength of the laser, when observing that the higher the wavelength the non-linear effects of the fiber affect communication, and that these effects can be mitigated by reducing the wavelength of the laser.

光纤传输中的线性和非线性效应

下面的工作通过在Python多范式编程环境中设计的图形用户界面(GUI)的实现，展示了数字光纤通信中线性和非线性现象的发生率，其中线性衰减和色散现象进行了评估。模态考虑了群速度色散(GVD)和三阶色散(TOD)，以及相位自调制SPM的非线性现象。该方法包括选择G.652标准下的单模光纤链路，并根据Mach-Zehnder (MZM)发射机和数字调幅OOK调制的信号改变通信系统的工作条件。结果表明，传输中的线性和非线性效应与输入高斯脉冲的时间宽度和激光的波长有关，当观察到波长越高，光纤的非线性效应会影响通信，并且可以通过减小激光的波长来减轻这些影响。
