DWDM Networks Basics

DWDMNetworks Basics

Hauv seem no, peb yuav xam ob lo lus nug: DWDM yog dab tsi? Dab tsi yog cov yam ntxwv ntawm DWDM networks?

DWDM (Dense Wavelength Division Multiplexing) yog ib qho kev sib txuas ntxiv ntawm kev sib txuas lus kho qhov muag. Nws tuaj yeem tso cov ntaub ntawv teeb liab los ntawm ntau qhov chaw ua ke ntawm ib khub optical fiber ntau, nrog txhua lub teeb liab ib txhij nqa ntawm nws tus kheej nyias lub teeb wavelength. Nrog DWDM, mus txog 160 wavelengths nrog qhov sib nrug ntawm 0.8/0.4 nm (100 GHz / 50 GHz grid) cais wavelengths lossis channels ntawm cov ntaub ntawv tuaj yeem kis tau los ntawm ib qho fiber ntau optical.

DWDM Networks Cheebtsam

Raws li txoj cai, rau DWDM tes hauj lwm, muaj plaub yam khoom siv tau pom hauv qab no uas feem ntau siv los ntawm cov neeg ua haujlwm IT:

• Kho qhov muagtransmitters / txais

• DWDMmux/demux filters

• Kho qhov muagNtxiv/poob multiplexers (OADMs)

• Kho qhov muagamplifiers transponders (wavelength converters)
