WDM,Wavelength Division Multiplexing,是將兩種或多種不同波長(zhǎng)的光載波信號(hào)(攜帶各種信息)在發(fā)送端經(jīng)復(fù)用器(亦稱(chēng)合波器,Multiplexer)匯合在一起,并耦合到光線(xiàn)路的同一根光纖中進(jìn)行傳輸?shù)募夹g(shù);在接收端,經(jīng)解復(fù)用器(亦稱(chēng)分波器或稱(chēng)去復(fù)用器,Demultiplexer)將各種波長(zhǎng)的光載波分離,然后由光接收機(jī)作進(jìn)一步處理以恢復(fù)原信號(hào)。...[繼續(xù)閱讀]
