摘要

首先介绍了波分复用技术的基本原理，然后介绍了各种波分复用技术在城域/接入网中的一些特点。任何波分复用系统的目标都是通过在多个波长同时发送信号来增加光纤的传输容量。在城域/接入网建设中，提出了一种利用WDM技术的新可能性。密集波分复用(DWDM)系统能很好地满足长途网络的要求，而粗波分复用(CWDM)系统能保证城域/接入网体系结构的所有关键特性。因此，DWDM/CWDM技术的结合为解决城域/接入网的挑战提供了巨大的潜力和未来的发展前景。

The utilization of the DWDM/CWDM combination in the metro/access networks

We present the basic principles of WDM and then introduce some characteristics of various WDM approaches to the metro/access telecommunication networks. A goal of any WDM system is to multiply an optical fiber's transmission capacity by sending signals simultaneously at multiple wavelengths. Substantial attention is dedicated to presenting a new possibility of utilizing WDM technologies in building metro/access networks. The DWDM (dense WDM) system outstandingly satisfies the requirements of long-haul networks and the CWDM (coarse WDM) system promises all the key characteristics of metro/access network architectures. Therefore, the combination of DWDM/CWDM technologies can offer a great potential for solving challenges of the metro/access network with the prospects of future development.
