摘要
伴随大容量、高速通信需求的逐渐增多,光孤子通信成为科研人员关注的热点问题。光孤子属于一种光脉冲序列,在光纤远距离传输时相斥作用较弱从而保证保形传输,这是光孤子高效通信的基础。深入研究光纤通信系统中光孤子传输特性影响因素。首先建立光孤子传输模型,获取光纤损耗、初始啁啾以及光纤色散等光孤子传输特性因子;然后分析光纤损耗、初始啁啾以及光纤色散对光纤通信系统中光孤子传输特性的影响,结果显示:光纤通信系统中存在光纤损耗时,光孤子传输特性受其干扰;初始啁啾值不同设定下,光孤子传输特征会受其干扰;光纤色散值越大,对光孤子的传输特征的干扰越大。
With the increasing demand for high-capacity and high-speed communication,optical soliton communication has become a hot issue for researchers.Optical soliton belongs to a kind of optical pulse sequence,which is the basis of efficient optical soliton communication because of its weak repulsion effect in long-distance transmission of optical fibers,thus guaranteeing conformal transmission.The influence factors of optical soliton transmission characteristics in optical fiber communication system are deeply studied.Firstly,optical soliton transmission model is established to obtain the transmission characteristic factors of optical soliton,such as optical fiber loss,initial chirp and optical fiber dispersion.Then,the influence of optical fiber loss,initial chirp and optical fiber dispersion on the transmission characteristics of optical soliton in optical fiber communication system is analyzed.The results show that when there is optical fiber loss in optical fiber communication system,the transmission characteristics of optical soliton are not disturbed by its initial chirp value.Under the same settings,the propagation characteristics of optical solitons will be interfered by them;the larger the dispersion value of optical fibers,the greater the interference to the propagation characteristics of optical solitons.
