密集波分复用(DWDM)是组合一组光波长用一根(或一对)光纤进行传送的技术,它是一种能够在现有的光纤骨干网上提高带宽最有效的技术。本文旨在对DWDM技术特点的分析,在分析DWDM技术特点的前提下,以某干线DWDM传输系统为例,针对其光放的配置、色散补偿、偏振膜色散限制及光信噪比等几个参数做计算分析,从而对DWDM系统的实现情况进行验证,进一步丰富相关知识,提高对DWDM系统的认识。
Dense wavelength division multiplexing (DWDM) is a combination of a group of optical wavelengths transmitted with one (or a pair) of optical fibers, which is one of the most effective techniques for increasing bandwidth over an existing optical backbone. This paper aims to analyze the characteristics of DWDM technology. On the premise of analyzing the characteristics of DWDM technology, taking a trunk DWDM transmission system as an example, aiming at the configuration of optical amplifier, dispersion compensation, polarization film dispersion limit and optical signal- Parameters to do the calculation and analysis to verify the realization of the DWDM system to further enrich the relevant knowledge and improve the understanding of DWDM system.
