CWDM能有效节省光纤资源和组网成本,它解决了光纤短缺和多业务透明传输两个问题,主要应用在城域网汇聚和接入层,并且可在短时间建设网络并开展业务。由于CWDM具有低成本、低功耗、小体积等诸多优点,是一种低价格、高性能的传输解决方案,现在已经广泛应用于城域网传输。
CWDM is a good way to save optical resource and capital of networking. It solved the problems of shortage of fiber and multi-business transparent transmission. This technique is mainly used in metropolitan area network and access layer which can shorten the of constructing network and doing business. CWDM is wildly used in WAN for its low cost, low power dissipation,small size and other priorities. It is a cheap and efficient transmission solution.
