4CH 8CH 16CH 100GHz DWDM Module 8 Channel 16 Channel Mux Demux DWDM
DWDM (Dens Wavelength Division Multiplexing) yog pab pawg ntawm cov kho qhov muag yoj yoj yoj yoj uas tuaj yeem sib koom ua ke kom xa mus siv tib leeg xwb. Qhov no yog lub tshuab thev naus laus zis siv los txhawm rau txhawm rau txhawm rau ntawm cov kab hluav taws xob kho qhov muag uas twb muaj lawm. Qhov tseeb dua, thev naus laus zis yog txhawm rau txhawm rau sib npaug nruj qhov sib nrug ntawm ib tus neeg nqa khoom siv fiber ntau hauv cov khoom siv kom thiaj li ua kom tau txais txiaj ntsig ntawm kev ua tiav kev sib kis tau zoo (piv txwv li, kom ua tiav qhov sib faib me me lossis txo qis). Ua li no, rau qhov muab cov ntaub ntawv muaj peev xwm xa tawm, tag nrho cov naj npawb ntawm cov kho qhov muag xav tau tuaj yeem txo qis.
Khoom Piav Qhia
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 kub thiab ua haujlwm tau zoo nyob hauv txhua daim ntawv thov kev siv. Mux / DeMux cov qauv muab cov nqi qis qis kev tswj hwm kev daws teeb meem uas tsim nyog rau kev thauj mus los ntev, xov tooj cua, thiab nkag mus thov.

Qhov Zoo ntawm DWDM:
1. Multiplexer thiab demultiplexer ntawm kev sib xyaw DWDM system tau siv ntawm qhov kawg kis thiab tau txais qhov kawg raws li, uas yog, tsuas yog tus lej sib kis ntawm qhov kawg kis thiab tsuas yog demultiplexer ntawm qhov kawg tau txais. OTU cov cuab yeej hloov pauv (ib feem no kim dua)? Yog li ntawd, kev nqis peev hauv DWDM cov cuab yeej siv tshuab tuaj yeem txuag ntau dua 60%.
2. Cov txheej txheem DWDM sib xyaw siv tsuas yog cov khoom sib txuas ua ke (xws li cov lej sib npaug lossis cov lej sib txawv) ntawm qhov tau txais qhov kawg thiab qhov kawg kis. Cov neeg ua haujlwm sib tham hauv xov tooj tuaj yeem xaj ncaj qha los ntawm cov tuam txhab tsim khoom, txo cov khoom lag luam thiab txo nqi, yog li txuag cov cuab yeej siv. .
3. Qhib DWDM network kev tswj hwm lub luag haujlwm yog saib xyuas ntawm OTM (feem ntau yog OTU), OADM, OXC, thiab EDFA, thiab nws cov peev txheej peev nyiaj suav txog 20% ntawm tag nrho cov peev txheej ntawm DWDM system; thaum kev sib koom ua ke DWDM tsis xav tau OTM cov cuab yeej, nws Kev tswj hwm lub network tsuas yog lub luag haujlwm saib xyuas OADM, OXC, thiab EDFA. Ntau tus neeg tsim khoom tuaj yeem nkag mus rau kev sib tw, thiab nws cov kev tswj hwm lub network tuaj yeem txo qis ib nrab piv rau qhib kev tswj hwm DWDM network.
4. Txij li cov khoom siv sib txuam / sib cais ntawm kev sib xyaw DWDM yog cov cuab yeej siv tsis tau, nws yooj yim los muab ntau yam kev pabcuam thiab ntau tus lej cuam tshuam, tsuav yog lub nthwv dej ntawm cov cuab yeej kho qhov muag ntawm cov cuab yeej siv kawg ua tau raws li G. 692 tus qauv , uas tuaj yeem nkag mus rau txhua qhov kev pabcuam xws li PDH, SDH, POS (IP), ATM, txhawb 8M, 10M, 34M, 100M, 155M, 622M, 1G, 2.5G, 10G thiab lwm yam nqi ntawm PDH, SDH, ATM thiab IP Ethernet ? Zam kev qhib DWDM vim yog OTU, tsuas tuaj yeem siv lub kaw lus DWDM tau txiav txim siab qhov kho qhov muag nthwv dej (1310nm, 1550nm) thiab kis tus nqi ntawm SDH, ATM lossis IP Ethernet cov cuab yeej? Nws yog qhov yooj yim siv tsis tau lwm qhov cuam tshuam.
5. Yog tias cov cuab yeej siv laser txheej txheem ntawm cov cuab yeej siv kho qhov muag xws li SDH thiab IP routers tau teeb tsa zoo ib yam li tus pin ntawm tus qauv geometry, kev sib cuam tshuam yog tus qauv, nws yooj yim los tuav lub ntsaws, thiab kev txuas yog ntseeg tau. Txoj hauv kev no, cov neeg ua haujlwm tu yuav tuaj yeem hloov pauv lub taub hau laser ntawm cov xim tshwj xeeb raws li lub nthwv dej xav tau ntawm DWDM kev sib koom ua ke, uas muab cov xwm txheej yooj yim rau laser lub taub hau tsis ua haujlwm tu thiab zam qhov tsis zoo ntawm kev hloov tag nrho pawg thawj coj los ntawm chaw tsim tshuaj paus Cov nqi kho mob siab.
6. Tam sim no cov xim lub teeb ci ci tsuas yog kim dua li qhov niaj hnub siv 1310nm thiab 1550nm lub teeb ci ci, xws li 2.5G tus nqi xim lub teeb ci lub teeb ci tam sim no ntau dua 3,000 yuan, tab sis thaum txuas nrog DWDM system rau siv , Tus nqi ntawm lub kaw lus tau raug txo los ntawm ze li 10 npaug, thiab nrog rau cov ntawv thov loj ntawm cov xim siv lub teeb ci ci, nws tus nqi yuav nyob ze rau qhov pom kev zoo ib yam.
7. Cov khoom siv DWDM ua ke muaj cov qauv yooj yim thiab qhov loj me me, tsuas yog li ib feem tsib ntawm qhov chaw nyob uas qhib los ntawm DWDM, txuag cov chaw siv tshuab.
