机架式CWDM（4-8-16)通道-粗波分复用器CWDM-无源波分复用器-光纤无源器件--Sharetop Technology Co.Limited

- 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。
