WDM光传输系统仿真的设计(论文13000字)
摘要:
随着以IP为代表的数据业务的爆炸式和Internet在全世界范围内的迅速发展,对于网络带宽的需求与日俱增,出现了所谓的的“光纤耗尽”现象和对代表通信容量的带宽的“无尽渴求”现象。[2]5G时代对光纤技术提出了更高要求。
WDM是目前的主流技术,所以针对它的研究具有重要的现实意义。本论文使用optisystem软件将对WDM光传输系统重要部件掺饵光纤放大器EDFA和WDM光传输系统进行设计仿真。论文的主要工作及成果如下:首先对WDM光传输系统的组成以及影响光传输效果的色散和非线性进行分析,其次对掺饵光纤放大器EDFA进行设计仿真,验证掺铒光纤的同向泵浦,反向泵浦,双向泵浦不同长度的增益,根据数据选择性能更好的EDFA设计方案;最后用对WDM光传输系统进行仿真,得到2路、4路、8路信道下的系统性能。

WDM optical fiber transmission system simulation
Abstract:
With the explosion of data services represented by IP and the rapid development of the Internet worldwide, the demand for network bandwidth is increasing day by day, and the so-called "fiber exhaustion" phenomenon and the phenomenon of endless cravings for bandwidth which representing the communication capacity appear. .5G era puts higher requirements on fiber optic technology.

WDM is currently the mainstream technology, and its research has important practical significance.This paper uses optisystem software to design and simulate the EDFA,the important components of WDM optical transmission system, and WDM optical transmission systems.The main work and achievements of the thesis are as follows: First, analyze the composition of the WDM optical transmission system and the dispersion and nonlinearity that affect the optical transmission effect.Secondly, the design and simulation of the EDFA with fiber-doped fiber amplifier are carried out to verify the same direction pumping of erbium-doped fiber, reverse pumping, bidirectional pumping of different length gains, and better EDFA design according to data selection.Finally, the WDM optical transmission system is simulated to obtain the system performance under the 2, 4 and 8 channels.
Key words: WDM wavelength division multiplexing;WDM optical transmission system;chromatic dispersion;erb-doped fiber amplifier;optisystem
