Abstract

Non-Linear effects in Optical networks are occurred due to the refractive index of the optical transmitting medium depending on the intensity of light. One of the most commonly occurred non-linear effect in optical network is the Self phase modulation (SPM) phenomenon. The impact of self-phase modulation instigates distortions to the optical signal transmission over desired configuration of spectrally systematic wavelength division multiplexing (WDM) optical fiber transmission system. Here we imitated the results for fiber optical network on different lengths of fiber. We investigate the results on the basis of Q-factor, jitter, BER at multiple values of dispersion and bit rate. We had analyzed the variation in optical dispersion from -8ps/ns/km to 8ps/ns/km and had realized the result through eye diagram. We have observed the optical spectrum for input and output from of signal mediation. For multiple values of fiber length, Data rate, emission frequency we have examine the BER and Q-factor. The outcome is analyzed using optical software tool i.e. OPTSIM.

WDM光网络非线性效应的评价与分析

光网络中的非线性效应是由于光传输介质的折射率随光强的变化而产生的。光网络中最常见的非线性效应之一是自相位调制(SPM)现象。在光谱系统波分复用(WDM)光纤传输系统中，自相位调制的影响会引起光信号传输的畸变。本文对不同长度的光纤网络进行了仿真。我们根据q因子、抖动、在多个色散值和比特率下的误码率对结果进行了研究。我们分析了光色散从-8ps/ns/km到8ps/ns/km的变化，并通过眼图实现了结果。我们观察了信号中介的输入和输出的光谱。对于光纤长度、数据速率、发射频率等多个值，我们考察了误码率和q因子。利用光学软件OPTSIM对结果进行了分析。
