DWDM (Dense Wavelength Division Multiplexing) yog ib qho kev sib txuas ua ke uas siv ntau lub wavelengths los xa cov ntaub ntawv hla ib qho fiber ntau optical. Qhov no multiplexing txoj kev tso cai rau txhua lub wavelength ua hauj lwm raws li ib tug cais channel, ho expanding lub peev xwm ntawm optical fiber.
Hauv DWDM, muaj ob txoj hauv kev tseem ceeb: WAVE thiab LAMBDA.
WAVE yog ib lub channel tshwj xeeb uas muab pob tshab thiab muaj siab rau bandwidth nrog kev txhawb nqa rau txhua hom kev cai. Txoj hauv kev no muab kev sib txuas lus latency tsawg heev thiab suav nrog tus neeg nqa khoom xa khoom transponder. Yog li ntawd, WAVE yog qhov zoo tagnrho rau cov tuam txhab nrhiav kev txhim khu kev qha, nrawm, muaj peev xwm sib txuas lus daws teeb meem.
Ntawm qhov tod tes, LAMBDA yog ib txoj hauv kev uas siv, piv txwv li, qhov nruab nrab ntawm lub cev, xws li DCI (Data Center Interconnect). Qhov kev xaiv no muaj kev ywj pheej thiab kev ua kom muaj zog, tso cai rau cov neeg siv khoom siv lawv tus kheej cov cuab yeej thiab kho lawv cov haujlwm raws li lawv cov kev xav tau tshwj xeeb. LAMBDA yog qhov kev daws teeb meem zoo rau cov tuam txhab uas xav tau kev hloov pauv ntau dua thiab tswj hwm lawv cov kev sib txuas lus.
Yog li, DWDM yog lub thev naus laus zis tshiab uas tso cai rau cov ntaub ntawv muaj peev xwm kis tau los ntawm ib qho fiber ntau optical. Nrog rau WAVE thiab LAMBDA txoj hauv kev, cov tuam txhab tuaj yeem xaiv los ntawm kev mob siab lossis sib koom cov kev daws teeb meem, nyob ntawm lawv cov kev xav tau thiab kev nyiam, yog li ua kom muaj kev sib txuas lus zoo thiab ua tau zoo.
