DWDM multi-channel multiplexer /demultiplexer (Mux /DeMux) cov qauv muaj nyob ntawm ITU channel sib nrug ntawm 200GHz. Lawv ua rau pom qhov poob qis, tsis muaj qhov kub thiab tsis ua haujlwm tau zoo nyob rau hauv txhua qhov kev thov siv.Mux/DeMux cov qauv muab cov nqi qis qis kev tswj hwm kev daws teeb meem uas haum rau kev thauj mus los ntev, xov tooj cua, thiab nkag mus thov. -mode fiber ntau thiab siv ntau lub wavelengths ua cov nqa khoom tso cai rau txhua tus neeg xa xov xwm xa mus ib txhij hauv cov fiber. Piv nrog rau thoob ntiaj teb ib leeg-channel system, ntom nti WDM-DWDM tsis tsuas yog txhim kho kev sib txuas lus muaj peev xwm ntawm lub network, siv tag nrho cov bandwidth ntawm cov kho qhov muag fiber, tab sis kuj muaj ntau qhov zoo xws li nthuav dav yooj yim thiab txhim khu kev qha, tshwj xeeb tshaj yog nws tuaj yeem Kev nkag ncaj qha Muaj ntau yam kev pabcuam ua rau nws daim ntawv thov kev cia siab ci ntsa iab Hauv kev ua haujlwm tiag, txhawm rau txhawm rau tuaj yeem siv qhov tsim nyog tau txais kev pabcuam dav dav uas tau tsim los ntawm ib hom fiber ntau hauv 1.55 teev tsaus ntuj, qhov poob qis thaj tsam ntawm cov fiber yuav tsum tau muab faib ua ntau txoj kev kho qhov muag raws li qhov sib txawv sib txawv thiab qhov ntev, thiab Ib qho kho qhov muag channel tsim cov yoj yoj, uas yog qhov peb hu ua lub teeb yoj. Nyob rau tib lub sijhawm, tus demultiplexer tau siv los ua ke ntau yam cim qhia nrog sib txawv wavelengths ntawm qhov kawg kis. Cov teeb liab sib xyaw ua ke no tau sib sau ua ke mus rau hauv qhov kho qhov muag fiber rau teeb liab xa mus. Thaum xa mus rau qhov tau txais qhov kawg, cov no tau sib xyaw ua ke ntawm qhov sib txawv ntawm qhov sib txawv uas siv cov kho qhov muag demultiplexer. Cov teeb liab ntawm lub teeb sib txawv sib txawv tau tawg thiab sib cais rau hauv lub xeev thawj zaug kom paub txog kev ua haujlwm ntawm kev xa ntau lub cim sib txawv hauv ib qho fiber ntau.

Qhov Zoo DWDM:
DWDM kho qhov muag thauj network muab kev lag luam muaj txiaj ntsig, muaj peev xwm loj, muaj txoj sia nyob ntev, thiab hloov pauv tau yooj yim hauv cov phiaj xwm yav tom ntej, uas muaj kev cia siab zoo heev. Nws cov yam ntxwv tseem ceeb yog:
1, muaj peev xwm siab. Tus nqi ntawm txhua lub nthwv dej tuaj yeem ncav cuag 40Gbit / s, thiab ib qho fiber ntau tuaj yeem xa ntau dua 160 wavelengths.
2. Kev yoj yoj yoj yoj mus: Hauv WDM tes hauj lwm, kev ua tiav tau ua tiav los ntawm cov khoom siv yoj yoj-xaiv, thiab kev sib txuas sab saum toj ntawm ntau qhov ntawm qhov sib txawv ntawm cov yoj yoj sib txawv tau tsim.
3. Pob tshab. WDM kho qhov muag sib txuas network yuav muab qhov kev hloov pauv tshiab sib txawv ntawm SDH / SONET, uas yog, kev xa xov yoj yoj yoj yog ywj siab ntawm cov txheej txheem thiab tus nqi. Qhov no yog qhov txiaj ntsig tseem ceeb ntawm WDM kho qhov muag sib txuas network, uas tau lees tias cov kho qhov muag sib txuas tuaj yeem siv tau hauv cov kho qhov muag. Ib txoj cai twg tuaj yeem sib kis tau, thiab cov cim ntawm ntau tus nqi me ntsis kuj tseem tuaj yeem kis tau.
4, kev rov tsim dua tshiab: WDM kho qhov muag sib txuas network tuaj yeem paub txog kev rov tsim kho lub zog ntawm cov khoom siv kho qhov muag nthwv dej los ntawm kev sib txuas hla qhov muag (OXC) thiab kho qhov muag ntxiv / poob multiplexing (OADM) thev naus laus zis
5, Kev sib haum xeeb. Yuav kom lees paub los ntawm kev ua lag luam, WDM kho qhov muag sib txuas network yuav tsum tau sib xws nrog cov cuab yeej siv hluav taws xob qub, txuas nrog lub network sib txuas uas twb muaj lawm thiab tso cai rau cov cuab yeej siv tam sim no mus txuas ntxiv ua haujlwm, thiaj li tswj hwm qhov peev txheej thawj ntawm tus neeg siv.
