Nrog rau kev hloov pauv tas mus li ntawm Is Taws Nem thiab kev sib txuas lus digital, ua ke nrog kev xav tau ntau ntxiv rau bandwidth, DWDM thev naus laus zis tau dhau los ua lub hauv paus tseem ceeb. Los ntawm kev tsim DWDM tes hauj lwm, peb tuaj yeem ua tiav qhov sib txawv ntawm cov teeb liab wavelength sib txawv nyob rau hauv tib lub optical fiber, nrog lub peev xwm los npog ultra-ntev deb li ntawm pua pua mus rau txhiab kilometers. DWDM tes hauj lwm, tus cwj pwm los ntawm lawv qhov kev ua tau zoo tshaj plaws ntawm kev sib kis ntev ntev thiab muaj peev xwm xa tau ntau lub wavelength signals nyob rau hauv ib qho kev kho qhov muag fiber ntau, tau dhau los ua qhov tseem ceeb hauv thaj tsam ntawm Is Taws Nem thiab kev sib txuas lus.
DWDM Technology yog dab tsi?
Dense Wavelength Division Multiplexing (DWDM) yog ib qho kev siv tshuab optical kis tau tus mob siab bandwidth thiab ntev-ntev cov ntaub ntawv xa mus los ntawm ib txhij xa ntau qhov sib txawv wavelengths ntawm cov teeb liab hla ib qho fiber ntau optical. Lub wavelength bands ntawm DWDM feem ntau muab faib ua C-band (1530 nanometers rau 1565 nanometers) thiab L-band (1565 nanometers rau 1625 nanometers). Qhov sib nrug ntawm lub wavelength yog hais txog qhov kev ncua deb ntawm qhov nyob ib sab wavelengths, thiab DWDM feem ntau siv qhov sib sib zog nqus wavelength sib nrug, nrog lub sijhawm wavelength ntawm 0.4nm, 0.8nm, thiab 1.6nm. Qhov sib sib zog nqus wavelength no ua rau tib lub sijhawm sib kis ntawm cov ntaub ntawv ntau dhau ntawm ib qho kev kho qhov muag fiber ntau, yog li ua tiav cov bandwidth siab thiab muaj peev xwm kho qhov muag fiber ntau. DWDM modules feem ntau muab faib ua DWDM modules tsis tu ncua thiab tunable modules, qhov sib txawv ntawm qhov niaj hnub DWDM modules tau tsau wavelengths, thaum tunable modules feature adjustable wavelengths.
DWDM Network ua haujlwm li cas?
Lub hauv paus ntsiab lus ua haujlwm ntawm DWDM thev naus laus zis yog raws li hauv qab no: Thaum tau txais cov teeb liab, cov teeb liab sib txawv tau hloov kho mus rau lawv cov wavelengths, nrog rau txhua lub wavelength sib haum mus rau ib qho kev ywj pheej channel. Tom qab kev hloov kho tiav, cov teeb liab no tau muab tso ua ke rau hauv ib qho kev kho qhov muag fiber ntau ntawm qhov kawg ntawm kev xa tawm, tsim cov teeb liab ntau wavelength optical. Thaum cov teeb liab multi-wavelength optical kis tau los ntawm fiber ntau optical mus rau qhov kawg tau txais, nws dhau mus wavelength demultiplexing, raug cais ua ntau wavelengths. Cov teeb liab demultiplexed yog tom qab ntawd demodulated, hloov cov teeb liab kho qhov muag rau hauv lub teeb liab hluav taws xob thiab rho tawm cov ntaub ntawv qub. Thaum kawg, cov ntaub ntawv ntws los ntawm txhua tus channel tau rov qab los rau lawv daim ntawv qub thiab xa mus rau lub hom phiaj ntaus ntawv.
Dab tsi yog Cov txiaj ntsig ntawm DWDM Networks
Tom qab qhia lub tswv yim ntawm DWDM thev naus laus zis thiab piav qhia nws txoj hauv kev ua haujlwm, tam sim no kuv yuav piav qhia txog qhov zoo ntawm DWDM thev naus laus zis. Los ntawm kev xa tawm DWDM network, koj yuav tau txais txiaj ntsig hauv qab no:
High Bandwidth thiab Muaj peev xwm: DWDM thev naus laus zis ua tiav bandwidth siab dua thiab muaj peev xwm los ntawm kev sib tw ntau lub wavelengths ntawm cov teeb liab ntawm ib qho khoom siv kho qhov muag piv rau cov khoom siv ib txwm siv. Nyob rau hauv keeb kwm yav dhau ntawm qhov kev xav tau loj zuj zus ntawm is taws nem thiab kev sib txuas lus, lub peev xwm siab dhau los ua qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov npe xws li cov yeeb yaj kiab siab, huab xam, thiab Internet ntawm Yam.
Kev xa mus ntev: DWDM thev naus laus zis siv cov wavelengths nrog cov teeb liab tsawg tsawg hauv cov txheej txheem kho qhov muag fiber ntau. Thaum ua ke nrog Transponders / EDFAs, nws tuaj yeem xa cov teeb liab hla ntau txhiab mais. Cov cwj pwm no yog qhov tseem ceeb tshwj xeeb rau kev sib txuas cov nroog nyob deb nroog, hla ciam teb thoob ntiaj teb, thiab txuas cov ntaub ntawv chaw nyob thoob plaws teb chaws. Qhov dav dav-ntev kis tau tus mob muaj peev xwm ntawm DWDM txuas ntxiv mus txog ntawm cov ntaub ntawv kev sib txuas lus, ua haujlwm tau zoo hauv kev sib txuas seamless thoob ntiaj teb.
High Reliability thiab Redundancy: Hauv DWDM network, txhua lub wavelength ua haujlwm ntawm nws tus kheej, kom ntseeg tau tias qhov tsis ua haujlwm lossis cuam tshuam hauv ib lub wavelength tsis cuam tshuam rau kev ua haujlwm ntawm lwm lub wavelength. Tsis tas li ntawd, nws tuaj yeem ua tiav nrog Optical Line Protection (OLP) rau cov kab rov ua dua ntxiv, thiab kev siv ob daim npav tso cai rau kev lag luam rov ua lag luam. Qhov kev rov ua dua tshiab no txhawb nqa kev ntseeg tau ntawm lub network, lav cov ntaub ntawv sib kis tsis muaj kev cuam tshuam. Tus cwj pwm no tuav tus nqi tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas xav tau kev ntseeg siab thiab kev ruaj ntseg yog qhov yuav tsum tau ua ua ntej, ua kom muaj kev lees paub zoo ntawm cov ntaub ntawv xa mus.
Tus nqi txo: DWDM thev naus laus zis tso cai rau cov ntaub ntawv muaj peev xwm xa mus rau cov khoom siv kho qhov muag fiber ntau uas twb muaj lawm, tshem tawm qhov xav tau rau kev teeb tsa fiber ntau tshiab thiab txo qis kev xa tawm thiab kev saib xyuas tag nrho. Qhov kev ua tau zoo ntawm tus nqi no ua rau DWDM thev naus laus zis tshwj xeeb yog qhov ntxim nyiam hauv kev siv tswv yim.
Flexibility thiab Scalability: DWDM tes hauj lwm muaj peev xwm ntawm dynamic configuration thiab kev tswj, uas yuav ua tau tiav los ntawm coupling nrog Reconfigurable Optical Add-Drop Multiplexers (ROADMs) kom pab tau tej thaj chaw deb thiab saj zawg zog pab faib. Qhov kev hloov pauv no txhawb nqa lub network kom haum raws li cov kev xav tau ntawm kev sib txuas lus tsis tu ncua. Raws li cov ntaub ntawv kev khiav tsheb nce ntxiv, kev ntsuas lub peev xwm hauv lub network yog qhov yooj yim raws li kev sib txuas ntxiv wavelengths. Nyob rau hauv lub xyoo tom ntej, nrog rau kev nce qib hauv kev sib txuas lus thev naus laus zis, DWDM tes hauj lwm yuav muab kev xaiv ntau dua ntawm kev xaiv wavelength, obviating qhov tsim nyog rau kev kho vaj tse dav dav.
Daim ntawv thov
Vim qhov xav tau rau cov neeg ua haujlwm hauv lub network kom xa cov ntaub ntawv ntau thiab kev sib txuas lus ntawm cov nroog sib txawv, thaj chaw, thiab txawm tias lub teb chaws, cov khoom siv uas muaj peev xwm ua tiav kev sib kis mus ntev yog xav tau. Lub peev xwm kis tau tus mob ntev ntawm DWDM thev naus laus zis tso cai rau cov neeg ua haujlwm ua cov ntaub ntawv xa mus dhau qhov kev ncua deb. DWDM thev naus laus zis tuaj yeem xa ob peb lub kaum os lossis txawm ntau pua lub wavelengths dhau ib qho kev kho qhov muag fiber ntau, ua rau cov neeg ua haujlwm ib txhij koom nrog ntau yam kev pabcuam, suav nrog cov ntaub ntawv, suab, thiab video. Los ntawm kev txhim kho qhov ua tau zoo ntawm kev siv cov peev txheej hauv network, DWDM thev naus laus zis muaj qhov muaj peev xwm loj thiab txhim kho tau zoo. Nrog kev txhim kho txuas ntxiv ntawm kev sib txuas lus thev naus laus zis, cov xov tooj ntawm cov channel hauv DWDM yuav txuas ntxiv mus ntxiv.
DWDM thev naus laus zis kuj tseem tuaj yeem siv los txuas ntau lub chaw khaws ntaub ntawv. Cov chaw khaws ntaub ntawv ua lub luag haujlwm tseem ceeb hauv kev pabcuam hauv internet, thiab Data Center Interconnect (DCI) yog lub hauv paus tseem ceeb hauv kev ua kom ntseeg tau thiab muaj cov kev pabcuam hauv chaw pabcuam. Txij li thaum cov chaw zov me nyuam feem ntau faib thoob plaws cheeb tsam sib txawv lossis txawm lub teb chaws, yuav tsum muaj kev sib txuas mus ntev, kev sib kis ntawm ntau cov ntaub ntawv kwj ntawm cov chaw zov me nyuam, thiab cov ntaub ntawv ntau dua thiab muaj peev xwm rov qab tau kev puas tsuaj. Qhov no yog qhov uas DWDM thev naus laus zis ua lub luag haujlwm tseem ceeb hauv DCI. Ntxiv nrog rau kev sib kis ntawm ultra-ntev-ntev thiab ntau-wavelength kis tau tus mob, DWDM tseem tuaj yeem pab txhawb cov ntaub ntawv thaub qab thiab xa mus rau cov chaw sib txawv ntawm cov ntaub ntawv, kom ntseeg tau cov ntaub ntawv thaub qab thiab cov tswv yim rov qab los daws cov teeb meem kho vajtse thiab kev puas tsuaj.
Hauv cheeb tsam cheeb tsam network, DWDM thev naus laus zis kuj tseem ua lub luag haujlwm tseem ceeb heev. Lub peev xwm kis tau tus mob ntev-ntev ntawm DWDM tuaj yeem npog txhua lub ces kaum ntawm lub nroog, sib cuam tshuam cov tes hauj lwm hauv nroog. Tsis tas li ntawd, DWDM txhawb nqa kev sib kis ntawm ntau lub teeb liab, ua tau raws li qhov xav tau ntawm kev sib txuas lus txhua hnub. Ntxiv mus, DWDM boasts siab kev ntseeg siab thiab redundancy. Nws qhov txawv wavelengths yog ywj siab ntawm ib leeg, yog li thaum ib lub wavelength muaj kev ua txhaum los yog cuam tshuam, lwm cov wavelengths tseem tsis cuam tshuam, yog li txhim kho kev ntseeg tau ntawm lub network thiab ua kom cov ntaub ntawv txuas mus ntxiv.
