Raws li qhov kev tshaj tawm tshiab tshaj plaws, DWDM system kev ua lag luam nyob rau thawj ib nrab ntawm 2019 pom qhov tseem ceeb ntawm lub xyoo. Txoj kev loj hlob yog ib feem vim qhov nyiaj tau poob qis hauv Suav teb nyob rau thawj ib nrab ntawm 2018, thaum ZTE raug tsoo los ntawm peb txwv. Yog li, soj ntsuam cov khw muag khoom tsis suav nrog Suav teb tuaj yeem nkag siab zoo txog kev lag luam kev noj qab haus huv thiab lub zog ntawm cov neeg xa khoom hauv lub sijhawm no.
Nws tau kwv yees tias cov nyiaj tau los rau DWDM lub ntiaj teb tsis suav nrog Suav tau nce 5% nyob rau thawj ib nrab xyoo 2019 piv nrog rau tib lub sijhawm ntawm xyoo tas los. Huawei feem koom kuj tseem qis dua Ciena thaum tsis suav nrog cov neeg xa khoom hauv Suav lag luam.
Ciena muaj ze li 30% ntawm kho qhov muag DWDM kev lag luam sab nraud ntawm Tuam Tshoj hauv thawj ib nrab ntawm 2019, vim nws cov thawj coj hauv North America thiab nthuav dav kev lag luam thoob ntiaj teb. Ciena cov nyiaj tau los ntau dua 20 feem pua ntawm xyoo xyoo.

HTFuture Dense Wavelength Division Multiplexers (DWDMs) yog cov kho qhov muag sib txuas ua ke, lossis sib txuam, thiab sib cais, lossis demultiplex ntau lub teeb pom kev zoo sib txawv ntawm cov yoj yoj sib txawv hauv ib qho fiber ntau. Los ntawm kev siv cov tswv cuab nyias zaj duab xis thev naus laus zis hauv kev txhim kho thiab tsim peb cov khoom lag luam DWDM, peb muab cov kev daws teeb meem rau 200 GHz, 100 GHz thiab 50 GHz ITU wavelength spacing applications. Kev cai teeb tsa yog muaj thaum thov.
