摘要
密集波分复用(DWDM)系统具有传输距离长、容量大、波道多、实施全透明传输、能组成全光层网络和工程造价相对较低等技术经济优势。文章阐明了DWDM与同步数字系列SDH的内在关系,介绍了整个DWDM系统的组网概况,并在DWDM传输平台上配置了SDH复用保护段设备,建设福建省调通中心到各地区电业局的光纤通信系统的传输平台。
There are technical and economic advantages to use Dense Wave Division Multiplexing system, such as longer transmission distance, bigger transmission capacity, multi-channel multiplex, transparent transmission, whole optical layer network and lower price of engineering. The internal relation between DWDM and Synchronous Digital Hierarchy is clarified in this paper, and the general situation of DWDM system in Fujian electric power is introduced. An equipment to protect SDH is installed in the transmission platform of DWDM, based on it the optical fiber transmission system platform from Fujian dispatch and communication center to the regional power bureaus is built.
