波分复用器

波分复用器

WDM Wavelength Division Multiplexing ，波分复用器
CWDM Coarse Wavelength Division Multiplexing ，稀疏波分复用器，也称粗波分复用器
DWDM Dense Wavelength Division Multiplexing ，密集波分复用器

WDM是将一系列载有信息、但波长差别的光信号合成一束，沿着单根光纤传输；在接收端再用某种要领，将各个差别波长的光信号离开的通信技术。这种技术可以同时在一根光纤上传输多路信号，每一路信号都由某种特定波长的光来传送，这就是一个波长信道。
在同一根光纤中同时让两个或两个以上的光波长信号通过差别光信道各自传输信息，称为光波分复用技术，简称WDM。光波分复用包括频分复用和波分复用。光频分复用（frequency-division multiplexing,FDM）技术和光波分复用（WDM）技术无明显区别，因为光波是电磁波的一部分，光的频率与波长具有简单对应关系。通常也可以这样理解，光频分复用指光频率的细分,光信道很是密集。光波分复用指光频率的粗分，光信道相隔较远，甚至处于光纤差别窗口。
光波分复用一般应用波长支解复用器息争复用器（也称合波/分波器）划分置于光纤两端，实现差别光波的耦合与疏散。这两个器件的原理是相同的。光波分复用器的主要类型有熔融拉锥型，介质膜型，光栅型宁静面型四种。其主要特性指标为插入损耗和隔离度。通常，由于光链路中使用波分复用设备后，光链路损耗的增加量称为波分复用的插入损耗。当波长11,l2通过同一光纤传送时，在与分波器中输入端l2的功率与11输出端光纤中混入的功率之间的差值称为隔离度。
现在市场使用WDM技术的产品主要有CWDM和DWDM。

CWDM是一种支持多协议传送的波分复用技术。CWDM系统利用复用器将差别波长承载的光信号复用至单根光纤进行传输，在链路的接收端，借助解复用器将剖析后的波长送给差别的光纤，连接到相应的接收设备。CWDM信道间隔通常比DWDM宽得多，为区别起见，故称其为粗波分复用。
