密集波分在传输领域的应用研究

Dense wavelength sivision of applied research in the transmission area

WDM光网络在不断进步的同时仍有大量问题需要解决,如设备价格昂贵,标准化问题,如何在不同用户间分配波长,如何对用户鉴权以及保留性问题,串扰问题,一体化网络管理机制和互操作问题等。文章对其关键技术进行了探讨。

（DWDM） systems to meet the growing bandwidth requirements,while also has unmatched networking advantages. WDM optical networks continues to progress,while there is still a large number of problems to be solved, such as the equipment is expensive,standardization issues,how the distribution of wavelengths between different users, how user authentication and to preserve the issues,crosstalk issues,an integrated network management mechanisms and interoperability issues. This article discusses its key technologies.
