波分復(fù)用器

WDM Wavelength Division Multiplexing ，波分復(fù)用器
CWDM Coarse Wavelength Division Multiplexing ，稀疏波分復(fù)用器，也稱粗波分復(fù)用器
DWDM Dense Wavelength Division Multiplexing ，密集波分復(fù)用器

WDM是將一系列載有信息、但波長(zhǎng)不同的光信號(hào)合成一束，沿著單根光纖傳輸；在接收端再用某種方法，將各個(gè)不同波長(zhǎng)的光信號(hào)分開(kāi)的通信技術(shù)。這種技術(shù)可以同時(shí)在一根光纖上傳輸多路信號(hào)，每一路信號(hào)都由某種特定波長(zhǎng)的光來(lái)傳送，這就是一個(gè)波長(zhǎng)信道。
在同一根光纖中同時(shí)讓兩個(gè)或兩個(gè)以上的光波長(zhǎng)信號(hào)通過(guò)不同光信道各自傳輸信息，稱為光波分復(fù)用技術(shù)，簡(jiǎn)稱WDM。光波分復(fù)用包括頻分復(fù)用和波分復(fù)用。光頻分復(fù)用（frequency-division multiplexing,FDM）技術(shù)和光波分復(fù)用（WDM）技術(shù)無(wú)明顯區(qū)別，因?yàn)楣獠ㄊ请姶挪ǖ囊徊糠郑獾念l率與波長(zhǎng)具有單一對(duì)應(yīng)關(guān)系。通常也可以這樣理解，光頻分復(fù)用指光頻率的細(xì)分,光信道非常密集。光波分復(fù)用指光頻率的粗分，光信道相隔較遠(yuǎn)，甚至處于光纖不同窗口。
光波分復(fù)用一般應(yīng)用波長(zhǎng)分割復(fù)用器和解復(fù)用器（也稱合波/分波器）分別置于光纖兩端，實(shí)現(xiàn)不同光波的耦合與分離。這兩個(gè)器件的原理是相同的。光波分復(fù)用器的主要類型有熔融拉錐型，介質(zhì)膜型，光柵型和平面型四種。其主要特性指標(biāo)為插入損耗和隔離度。通常，由于光鏈路中使用波分復(fù)用設(shè)備后，光鏈路損耗的增加量稱為波分復(fù)用的插入損耗。當(dāng)波長(zhǎng)11,l2通過(guò)同一光纖傳送時(shí)，在與分波器中輸入端l2的功率與11輸出端光纖中混入的功率之間的差值稱為隔離度。
現(xiàn)在市場(chǎng)使用WDM技術(shù)的產(chǎn)品主要有CWDM和DWDM。

粗波分復(fù)用器 (80)

CWDM是一種支持多協(xié)議傳送的波分復(fù)用技術(shù)。CWDM系統(tǒng)利用復(fù)用器將不同波長(zhǎng)承載的光信號(hào)復(fù)用至單根光纖進(jìn)行傳輸，在鏈路的接收端，借助解復(fù)用器將分解后的波長(zhǎng)送給不同的光纖，連接到相應(yīng)的接收設(shè)備。CWDM信道間隔通常比DWDM寬得多，為區(qū)別起見(jiàn)，故稱其為粗波分復(fù)用。
