CWDM Kev daws los ntawm focc
CWDM thev naus laus zis koom nrog cov ntawv thov CWDM cov khoom lag luam xws li CWDM MUX / DEMUX, CWDM SFP, CWDM ntxiv-poob multiplexer thiab lwm yam khoom muaj feem xyuam. Kab lus no yog hais txog dab tsi yog CWDM sawv rau, qhov zoo ntawm CWDM thiab yam khoom siv lossis cov khoom siv xav tau rau cov kev daws teeb meem CWDM.
Raws li peb paub, broadband tau tshaj tawm lub ntiaj teb tshiab rau cov neeg tuaj yeem, tag nrho ntawm cov peev txheej siab thiab nrawm nrawm dua. Cov kab ke hluav taws xob fiber ntau yuav tsum muaj ob txoj hlua ntawm fiber ntau - ib qho rau kev xa xov thiab ib qho rau txais cov cim. Tab sis, dab tsi tshwm sim thaum koj xav tau ntxiv kev pabcuam lossis cov qhua tuaj noj mov, nws muaj peb txoj kev xaiv, 1) txhim kho ntau txoj kab hluav taws xob, 2) nce qhov system bitrate rau multiplex ntau cov cim lossis 3) wavelength faib multiplexing. Pom tseeb, thawj ob qho kev xaiv yog txhua qhov yuav tsum tau nqis peev ntau dua rau cov kab ke uas twb muaj lawm, uas yog txhua yam tsis raug nqi tsis zoo. Tsuas yog txoj kev xaiv thib peb, WDM (wavelength division multiplexing), tso cai siv cov khoom siv hluav taws xob thiab cov xov hluav taws xob tam sim no thiab tsuas sib koom cov fibers los ntawm kev xa cov kab sib txawv ntawm cov xim sib txawv (wavelengths) ntawm lub teeb.
Muaj Coarse Wavelength Division Multiplexing thiab Dense Wavelength Division Multiplexing rau WDM thev naus laus zis, Coarse Wave Division Multiplexing (CWDM) thev naus laus zis yog cov kev daws teeb meem zoo tshaj plaws rau kev nthuav tawm bandwidth thiab muaj ntau yam zoo dua DWDM thev naus laus zis hauv nqe lus ntawm cov nqi system, teeb tsa, txij nkawm, thiab scalability.
Coarse wavelength division multiplexing tau paub los ntawm kev siv CWDM modules, uas sib txuas los yog sib cais txog 18 lub teeb tsa hluav taws xob tshaj ib qho txuas fiber ntau. Txhua lub teeb liab nqa tuaj yeem ua tus nqi sib txawv thiab hauv ntau hom. CWDM thev naus laus zis siv ITU txheem 20nm spacing sib txawv ntawm qhov ntev, ntawm 1310nm txog 1610nm. CWDM yog coarse wavelength multiplexing thev naus laus zis rau nroog thiab nkag tau cov tes hauj lwm.
CWDM Modules siv cov txheej txheem nyias-zaj duab xis thiab micro optics pob thev naus laus zis uas muaj nyob hauv ob qho kev teeb tsa tseem ceeb: CWDM Mux / Demux modules thiab CWDM OADM modules. Cov CWDM kev daws teeb meem peb muaj muaj lub peev xwm multiplex mus txog 9 (8 + 1) sib txawv fiber ntau sib txuas dhau ntawm tib lub cev hluav taws xob. Kev ua haujlwm ntau yuav ncav cuag li120Km, nyob ntawm qhov siv tau kho qhov muag siv tau.Qhov tag nrho muaj peev xwm ntau yog 1.25G x 9 = 11.25G.
Cov txiaj ntsig ntawm CWDM
Cov khoom siv passive uas tsis muaj hluav taws xob
Tus nqi qis dua rau ib qho tshaj li DWDM
Scalability loj hlob tuaj yeem ua kom muaj fiber ntau raws li xav tau
Nrog tus nqi me lossis tsis nce nqi
Raws tu qauv pob tshab
CWDM tuaj yeem muab kev sib txuas rau ntau Cov Kev Txuas Hluav Taws Xob uas yog siv cov txheej txheem zoo rau lub xov tooj ntawm tes ntau tshaj ib qho ntawm cov xov fiber ntau.
FOCC muab CWDM modules nrog ntau yam ntawm cov khoom sib txuas thiab cable ntev thiab xaiv yeem stainless tub ntxhais pob ntim lossis cov thawv txheem pob thiab kom tau raws li koj xav tau. Peb muab 2 channel CWDM Mux / Demux, 4 channel CWDM Mux / Demux… txog 18 channel CWDM Mux / Demux thiab 1-16 tshooj CWDM OADM. Peb cov CWDM modules raug teeb tsa los ntawm tus naj npawb ntawm cov channel rau txhua tus neeg siv kev tshaj lij channel, thiab tuaj yeem ua ke nrog cov kais dej thiab kuaj kom pom kev ua tiav CWDM. Txhua yam ntawm cov qauv CWDM no los nrog qhov loj me me, Tsawg Tsis Pom Zoo, Vij ob thiab kev ywj pheej ib puag ncig.
