Tsawg Muaj Zog Siv Tau, Kev Tu Kom Yooj Yim Thiab Yooj Yim Khoom Siv Yooj Ywg
May 08, 2018

Qhov tseem ceeb tshaj plaws ntawm CWDM yog nws cov cuab yeej tsis tshua muaj nqis. Cov xwm txheej muaj tau pib ua ntej. Ntxiv rau, CWDM lwm qhov kom zoo dua yog tias nws tuaj yeem txo cov nqi khiav lag luam ntawm lub network. Vim tias CWDM cov khoom siv me me, muaj tsawg zog hauv kev siv hluav taws xob, yooj yim kho, thiab yooj yim rau hauv lub hwj chim, 220V AC zog yuav siv tau. Vim muaj tsawg tus wavelengths, lub rooj tsavxwm muaj tsawg tus nqi thaub qab. Tsis muaj kev tshwj xeeb rau kev siv fibers siv 8-yoj CWDM. G.652, G.653, thiab G.655 optical fibers yuav siv tau, thiab cov khoom siv optical optical yuav siv tau. CWDM systems yuav ua rau kom muaj peev xwm kis tau ntawm cov ntaub fibers optical thiab nce kev siv cov khoom siv fiber ntau qhov muag. Kev tsim kho ntawm cov chaw hauv nroog loj yog tab tom muaj feem xyuam ntawm cov khoom siv fiber ntau ntau lossis cov nqi kim heev ntawm cov ntawv xauj tsev. Ib hom kab nrig wavelength division multiplexing system tuaj yeem muab 8 qhov kev kho qhov muag thiab txog 18 qhov kev kho qhov muag raws li ITU-T G.694.2 specification. Ib qho zoo dua ntawm CWDM yog nws qhov loj me thiab tsawg zog. CWDM lub tshuab lauj tsis tas yuav tsum muaj cov chilers thiab cov dej tswj kom sov, ces lawv tuaj yeem txo hwj chim ntau dua. Piv txwv, DWDM systems haus txog 4W ntawm fais fab tuag ib lub laser, thaum CWDM lasers tsis txias cia li 0.5W ntawm lub zog. Lub simplified laser module nyob rau hauv CWDM system txo qhov luaj li cas ntawm qhov kho qhov muag pom tau zoo dua. Lub simplification ntawm cov qauv ntaus ntawv kuj txo qhov loj ntawm lub cuab yeej thiab txuag chav chaw. Muab piv rau tus qauv TDM cov qauv, CWDM muaj kev ceev thiab raws li kev cai, uas ua rau nws tsim kom muaj kev pabcuam cov ntaub ntawv ceev-ceev hauv cov chaw hauv cheeb tsam. Nyob rau hauv tus txiv neej, muaj ntau ntau cov kev cai thiab cov kev pabcuam nrog kev sib txawv. CWDM muab txoj kev sib tshuam sib luag nrog cov nqi sib txawv, xws li Ethernet, ATM, POS, thiab SDH, ntawm ib lub tshuab fiber ntau. CWDM yog pob tshab. Kev sib deev thiab ntxiv / tso tawm ntau ntxiv tso cai rau tus neeg siv mus tso qee lub suab qis tsis muaj kev hloov ntawm hom thawj qhov teeb meem. Hauv lwm lo lus, cov txheej txheem kho qhov muag tau muab ib lub qauv thauj uas yog ua haujlwm ntawm cov lag luam txheej. CWDM muaj kev ywj pheej zoo thiab muaj lub zog loj. Rau qhov chaw lag luam loj, qhov kev ywj pheej ntawm cov kev pabcuam, tshwjxeeb tshaj yog qhov kev pabcuam thiab qhov kev lagluam nthuav dav li kev lagluam, tseem ceeb heev. Kev siv CWDM cov cuab yeej siv tau qhib qhov kev pab rau cov neeg siv hauv ib hnub los yog ob peb xuab moos, thiab tuaj yeem ua rau lub peev xwm ntxiv los ntawm qhov kev sib txuas ntawm OTU board raws li cov nqi tsheb nce. Txhim kho kev lag luam zoo. Daim ntawv thov CWDM systems nyob rau hauv qhov chaw loj hauv cheeb tsam chaw ua haujlwm yuav ua rau rov qab kho qhov muag tau. Rov qab los ntawm cov txheej txheem kho qhov muag zoo dua qub dua rov qab los ntawm cov hluav taws xob txheej txheem. Xav tias qhov kev kho rov qab los ntawm qhov seem txheej txheem yog kev ywj pheej ntawm qhov kev pab thiab tus nqi, qee lub tshuab tsis muaj kev tiv thaiv hauv lawv lub tshuab siv tau CWDM kev tiv thaiv. Vim tias qhov zoo tshaj plaws ntawm CWDM cov cuab yeej, CWDM tau txais ntau dua thiab ntau daim ntawv thov hauv kev sib txuas lus, xov tooj cua thiab TV, cov tuam txhab lag luam, thiab cov koom txoos hauv tsev kawm ntawv.
