摘要
针对城域传输网的特点,提出了稀疏波分复用方案。研究了城域网CWDM光传输系统中的数字包封器技术,对数字包封器的原理、基本结构及其对系统部件的基本要求进行了深入的探讨。并在此基础上提出了系统硬件和软件实现的解决方案,对数字包封器技术在城域网CWDM光纤传输系统中的应用前景进行了大胆的预测。
Aiming at the character of optical transport network of MAN, a solution of CWDM is put forward. Digital wrapper technology, which is used in CWDM optical transport network of CWDM, is studied. The principle and the basic structure of the digital wrapper and the basic demand for system parts are described in this article. Implantations of the hardware and software is present. At last, forecasting boldly the future of digital wrapper technology, which is used in CWDM optical transport network.
