- 产品概述 -
粗波分复用器(CWDM)是一种面向城域网接入层的低成本WDM传输技术。从原理上讲,CWDM就是利用光复用器将不同波长的光信号复用至单根光纤进行传输,在链路的接收端,借助光解复用器将光纤中的混合信号分解为不同波长的信号,连接到相应的接收设备。
- 产品特性 -
CWDM采用薄膜滤波片技术,波长稳定性好,可根据要求配置升级端口具有较低的插损,具有较高隔离度,性能稳定性和高温度稳定性.,产品具有低插损,高通道隔离度,宽带宽及低温度敏感性等特点。一般分为4通道,8通道,16通道或者多达18通道粗波分复用器。由于粗波分系统低插损的要求,在通道数多时,模块可添加跳片以降低各通道插损。普通的粗波分封装形式分为:ABS盒式,LGX 盒式和19英寸1U机箱封装等。
- 产品应用 -
CWDM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,可在短时间建网并开展业务。现已广泛应用于城域网传输和CATV系统。
