无源波分系统在城域网中的应用探讨

Application of Passive Wave Division Multiplexing System in Metropolitan Area Network

从设备性能参数进行理论推导,并在试验环境和现网带业务条件下分别进行兼容性测试和传输性能测试,从技术上论证了在城域网中引入无源波分系统的可行性。通过与现有承载模式建设成本的比较,证明了无源波分系统的经济性,并探讨了在现网中应用该系统需要解决的支撑系统和维护习惯等相关工程问题。

Theoretical derivation is done from equipment performance parameters, and compatibility test andtransmission performance test also carried out respectively under test environment and existing network bandbusiness conditions, which technically demonstrates the feasibility of introducing Passive WDM system inmetropolitan area network. By comparing the construction cost with the existing bearer mode, the economicsof the passive WDM system is proved, and the related engineering issues such as support system andmaintenance habits that need to be solved when the system is applied in the existing network are discussed.
