Hauv txoj ntsiab cai, CWDM siv optical multiplexer los ua ntau txoj haujlwm kho qhov muag ntawm cov yoj hluav taws xob sib txawv mus rau ib qho kho qhov muag fiber ntau rau kev xa. Ntawm qhov tau txais qhov kawg ntawm qhov txuas, nrog kev pab ntawm optical demultiplexer, cov sib xyaw ua ke nyob rau hauv cov hluav taws xob kho qhov muag tau decomposed rau cov cim ntawm cov wavelengths sib txawv thiab txuas nrog cov tau txais cov khoom siv.
Cov lus txhawb zoo
Qhov zoo tseem ceeb tshaj ntawm CWDM yog cov khoom siv qes. Lwm qhov zoo dua ntawm CWDM yog tias nws tuaj yeem txo tus nqi ua haujlwm ntawm lub network. Vim tias qhov loj me me, kev siv hluav taws xob tsawg, kev saib xyuas yooj yim thiab yooj yim lub zog ntawm cov cuab yeej CWDM, 220V AC fais fab mov siv tau. Vim tias nws tsawg tsawg ntawm wavelengths, tus nqi ntawm daim npav board thaub qab tau me me. Cov kab ke CWDM tuaj yeem txhim kho qhov kev sib kis tau ntawm cov khoom siv fiber ntau thiab kev siv cov khoom siv fiber ntau.
Lwm qhov zoo dua ntawm CWDM yog nws qhov loj me thiab qhov qis zog noj. Cov ntsuas hluav taws xob tau yooj yim hauv CWDM system txo cov ntim ntawm qhov sib xyaw ua ke optical transceiver module, thiab cov qauv siv yooj yim kuj tseem txo cov ntim ntawm cov khoom siv thiab txuag chaw hauv chav. CWDM muaj kev yoog raws thiab yooj yim. Rau cov chaw ua lag luam hauv cheeb tsam, qhov hloov tau yooj yim ntawm kev pabcuam, tshwj xeeb tshaj yog kev ceev ntawm kev pabcuam thiab kev muaj peev xwm nthuav dav nrog kev txhim kho kev lag luam yog qhov tseem ceeb heev. Vim tias cov txiaj ntsig zoo saum toj no ntawm CWDM Technology, CWDM tau siv dav hauv kev sib tham, xov tooj cua thiab TV, koom tes network, thaj chaw hauv nroog thiab lwm thaj chaw.
Tsis txaus ntseeg
Qhov teeb meem loj tshaj ntawm CWDM Technology yog tias nws cov txiaj ntsig kom zoo dua li cov cuab yeej siv DWDM tseem tsis tau pom tseeb. Tam sim no, tus naj npawb ntawm cov kho qhov muag (nthwv dej) txhawb nqa los ntawm CWDM cov khoom siv tsis pub dhau 8, feem ntau yog vim kev tsim khoom tsis tiav ntawm E-band optical transceiver module. Tsis tas li ntawd, g.652c optical cable, uas tshem tawm cov dej nqus dej siab, yog siv tsawg hauv lub network tam sim no, yog li kev thov kev lag luam rau E-band optical transceiver module tsis loj. Tseem tshuav ntau yam teeb meem kev siv tshuab hauv CWDM uas muaj tus nqi siab dua thiab sib kis ntev dua. Xws li cov dispersion ntawm 10G system, ultra wideband optical amplification technology thiab li ntawd. Tsis tas li ntawd, kev ua haujlwm ntawm cov txheej txheem xav tau ua kom nrawm dua, tshwj xeeb tshaj yog cov kev taw qhia ntawm cov neeg ua haujlwm hauv cov haujlwm ntawm cov haujlwm kev lag luam
