摘要
在光通信传输媒体中不可避免存在干扰,随着科技的发达,人们利用ULH-DWDM光传输来提高传输速度、传输容量和传输距离。节省了大量的中继器,减少建设成本,增强系统的质量和可靠度。ULH-DWDM光通信传输系统中有许多的关键技术,如光放大技术、色散补偿技术、非线性抑制、码型调制技术等,本文将对这些技术及其研究动态作深入分析和探讨。
There is no avoidance interfere in telecom transmission media,with the development oftechnology,people use ULH-DWDM fiber transmission to enhance capacity and distance.It saves muchelectronic trunk devices, induces much cost,raises system’s transmission quality and ability. The keyproblems in fiber transmission ,such as magnifying technology,dispersion compensating technology,nonlinearcheecking technology,code pattern modulating technology.etc.In this paper,it will analyze anddiscuss these technologies and their research deeply.
