摘　　要：在全业务经营下,针对中国移动较为薄弱的管道、光缆等基础资源不能满足新兴的有线宽带业务以及LTE业务对光缆纤芯不断增大的需求,提出了无源CWDM技术,可以很好地解决基础管线资源紧张情况下各种业务如何快速开通的难题。通过介绍CWDM的技术原理及特点、无源CWDM设备与新建光缆的优劣对比,并对无源CWDM设备应用场景进行详细分析,指出无源CWDM技术在全业务时代具有广泛的应用前景。Under the full-service operation, the pipeline and optical cable resources of China Mobile are weak, which cannot meet the requirements of the wired broadband and LTE business for optical cable fiber core. Then the CWDM technology is proposed to solve the rapid opening of various business in the condition of basic pipeline resource constraints. The principles and characteristics of CWDM technology are introduced;in the meantime, the advantages and disadvantages of passive CWDM equipment and new optical cables are compared. In addition, the application scenarios of passive CWDM equipment are analyzed in detail, which shows that the CWDM technology has wide application prospect in the era of full-service.
