应用
凯勤科技推出的CWDM设备,可分为单纤单向、单纤双向和双纤双向粗波分复用设备,能实现点对点组网应用和组环应用。单纤双向设备可通过一根光纤双向传输4波业务,单纤单向设备可通过一根光纤单向传输8波业务,双纤双向设备可通过一对光纤双向传输8波业务。采用CWDM设备对SDH城域网扩容,非常适合城域网多业务传送,并在成本、容量、可扩展性方面有非常大的优势,是运营商城域网扩容的理想解决方案。
CWDM 技术解决了光纤短缺和多业务透明传输两个问题,低成本是它的最大优势,主要应用在城域网汇聚或接入层面,对于竞争区域的运营者有着比较大的吸引力,可以在短时间建设网络并开展业务。目前CWDM 在国内市场上已经得到了越来越多的应用。
CWDM与RPR、SDH环网结合,即可以使现有的网络容量倍增,又能利用RPR、SDH设备的自愈、保护倒换和业务调度灵活的优点,从而构成高效率、高可靠性和大容量的信息高速公路。
