DWDM Solution Design and Cost quotation Link info:
Thaum kev nthuav dav muaj peev xwm tshwm sim hauv kev sib txuas lus hauv ib txwm muaj, Lub Sijhawm Division Multiplexer (TDM) thiab Chaw Ua Haujlwm Multiplexer (SDM) tau txais yuav. Ob leeg ntawm kev sib txuas lus siv ib lub teeb liab wavelength rau cov ntaub ntawv xa mus. Txawm li cas los xij, txoj kev sib kis no tsis ua kom tag nrho cov khoom siv kho qhov muag nrog lub peev xwm loj raws li qhov nruab nrab kis tau tus mob, ua rau cov khib nyiab loj heev. Txhawm rau daws qhov teeb meem, DWDM tech los rau hauv kev lag luam kho qhov muag. Tom qab ntawd hauv cov ntawv tshaj tawm no, kev taw qhia rau DWDM yuav nthuav dav.
DWDM yog dab tsi?
DWDM, luv luv rau Dense Wavelength Division Multiplexing, yog ib lub tshuab uas sib sau datum los ntawm ntau qhov chaw ntawm ib qho khoom siv fiber ntau. Nws tau siv rau hauv fiber ntau optical transceiver (yog li DWDM XFP, DWDM tunable SFP + thiab lwm yam tshwm sim) kom nce bandwidth tshaj cov fiber ntau optic qaum, thiab yog nrog txhua lub teeb liab ib txhij nqa ntawm nws tus kheej nyias lub teeb wavelength.
Qhov "dense" ntawm no txhais tau hais tias cov wavelength channels nyob ze rau ib leeg. Dhau li ntawd, DWDM, mus txog 80 (thiab theoretically ntau dua) cais wavelengths los yog raws cov ntaub ntawv yuav multiplexed mus rau hauv ib lub teeb kwj kis ntawm ib tug fiber optic. DWDM systems xav tau kev suav cov lej ntawm qhov sib npaug ntawm lub zog ib channel, uas yog qhov nyuaj ntxiv thaum cov channel tau ntxiv thiab tshem tawm lossis thaum nws siv hauv DWDM lub nplhaib sib txuas, tshwj xeeb tshaj yog thaum cov tshuab suav nrog optical amplifiers.
Qhov zoo ntawm DWDM
Hais txog kev siv thev naus laus zis thiab kev lag luam, lub peev xwm los muab cov peev xwm tsis muaj peev xwm kis tau tus mob yog qhov zoo tshaj plaws ntawm DWDM thev naus laus zis. Tam sim no kev nqis peev hauv fiber ntau tuaj yeem tsis tsuas yog khaws cia tab sis ua kom zoo dua los ntawm qhov tsawg kawg yog 32. Raws li qhov xav tau hloov pauv, muaj peev xwm ntxiv tau, los ntawm kev hloov khoom siv yooj yim lossis los ntawm kev nce cov lambdas ntawm cov fiber ntau, tsis muaj kev hloov kho tshiab. . Lub peev xwm tuaj yeem tau txais rau tus nqi ntawm cov cuab yeej siv, thiab cov peev txheej cog fiber ntau tau khaws cia.
Bandwidth ib sab, qhov kev ua tau zoo tshaj plaws ntawm DWDM tuaj yeem raug sau tseg raws li hauv qab no:
Pob tshab:vim tias DWDM yog nrog cov txheej txheem lub cev, nws tuaj yeem ua pob tshab txhawb nqa ob qho tib si TDM thiab cov ntaub ntawv tawm tswv yim xws li ATM, Gigabit Ethernet, ESCON, thiab Fiber Channel nrog qhib kev cuam tshuam hla ib txheej txheej ntawm lub cev.
Scalability:DWDM tuaj yeem ua kom muaj kev nplua nuj ntawm cov fiber ntau tsaus nti hauv ntau thaj chaw hauv nroog thiab cov chaw lag luam kom ua tau raws li qhov kev thov kom muaj peev xwm ntawm qhov taw tes-rau-taw tes txuas thiab ntawm qhov txuas ntawm SONET / SDH rings uas twb muaj lawm.
Dynamic provisioning:ceev, yooj yim, thiab dynamic muab kev sib txuas hauv network muab cov neeg muab kev pabcuam muaj peev xwm muab cov kev pabcuam siab-bandwidth hauv hnub ntau dua li lub hlis.
Kev siv ntawm DWDM
Nrog ntau qhov zoo, DWDM yog ib txwm siv rau ntau lub sijhawm, tom qab ntawd qee qhov kev siv tseem ceeb ntawm DWDM tau qhia raws li hauv qab no:
Qhov kev txwv deb tuaj yeem kov yeej los ntawm kev thauj cov ntaub ntawv ntawm ib lossis ntau qhov chaw lag luam thiab ib lossis ntau dua SANs hla txheej kho qhov muag siv DWDM. Ntxiv nrog rau kev kov yeej cov kev txwv deb, DWDM tuaj yeem txo cov kev xav tau fiber ntau hauv SANs.
DWDM tuaj yeem siv los tshem tawm tag nrho cov khoom siv, SONET ADMs. Qhov kev hloov pauv no, uas yuav ua rau theem thib ob ntawm SONET tsiv teb tsaws, tso cai rau routers thiab lwm yam khoom siv los hla SONET cov cuab yeej thiab cuam tshuam ncaj qha rau DWDM thaum ua kom yooj yim ntawm kev khiav tsheb los ntawm IP / ATM / SONET rau POS mus rau qhov kawg IP ncaj qha hla txheej txheej kho qhov muag.
Ob leeg ESCON thiab FICON xav tau ib khub ntawm fibers rau txhua tus channel. Los ntawm multiplexing cov channel hla DWDM thauj, kev txuag nyiaj tseem ceeb tuaj yeem ua tiav.
DWDM muaj peev xwm nthuav dav thiab muaj peev xwm ua tau raws li cov bandwidth thaub qab yam tsis tas yuav nruab cov fibers tshiab, yog li nws tau npaj txhij rau kev pabcuam kev sib txuas lus ntev.
DWDM kuj tseem tuaj yeem siv rau hauv ntau lub network xws li Sensor Networks, Chaw Taws Teeb Radar Networks, Tele-spectroscopic txheej txheem tswj network, thiab ntau lub network ntxiv.
Los ntawm kev siv ob lub fibers nkaus xwb, 100% kev tiv thaiv nplhaib nrog 16 cais kev sib txuas lus tuaj yeem tsim tau siv DWDM terminals vim cov no yog cov nplhaib kho tus kheej.
Txhawm rau ua kom tau raws li qhov xav tau ntawm kev lag luam loj hlob sai, DWDM system tuaj yeem siv rau cov nroj tsuag nyias nyias vim tias cov nroj tsuag no tsis tuaj yeem txhawb nqa tus nqi siab.
Nws ntseeg tau tias muaj kev xav tau zoo rau kev sib kis loj hauv kev lag luam kho qhov muag tam sim no. Txawm hais tias muaj peev xwm kis tau tus mob loj yog suav tias yog nws cov txiaj ntsig zoo, nws yuav pab txhawb kev txhim kho DWDM tech mus rau qhov loj. Tsis tas li ntawd, raws li cov thev naus laus zis zoo tshaj plaws rau kev sib txuas lus, tsis muaj qhov tsis ntseeg tias DWDM thev naus laus zis yuav hloov kho kev sib txuas lus yav tom ntej los ntawm kev tsim txiaj ntawm nws cov txiaj ntsig thiab kev siv ntau yam.
