Q1: CCWDM loj yog <>
Yog lawm, Piv nrog cov kab ke CWDM thev naus laus zis, CCWDM thev naus laus zis siv qhov chaw pub dawb qhov chaw muaj peev xwm txhim kho qhov kev ua kom zoo dua qub, hauv ib pob tau tsawg dua li 1/4 qhov loj ntawm cov qauv CWDM uas yooj yim.
Q2: Qhov txiaj ntsig tseem ceeb ntawm CCWDM yog dab tsi?
Cov txiaj ntsig tseem ceeb ntawm CCWDM Mux yog qhov siab yoj qhov tseeb thiab qhov chaw ruaj khov, qhov poob zoo tsis txaus, kev rho tawm siab thiab PDL tsawg (kev sib txig tsis nrog).
Q3: Qhov txheej txheem CCWDM txhawb nqa dab tsi?
Nws yog cov txheej txheem thiab tus nqi pob tshab txhawb cov kev siv xws li CWDM system, PON networks, thiab CATV Links.
Q4: Nws puas tuaj yeem siv hauv PON Network?

Paub ntau ntxiv txog WDM.
1. Dab tsi ntawm WDM?
WDM tuaj yeem raug cais mus rau CWDM (Sib Nqus Wavelength Division Multiplexing) thiab DWDM (Dense Wavelength Division Multiplexing). Cov channel qhov sib nrug ntawm CWDM yog 20nm, thiab qhov kis tau ntawm DWDM channel yog los ntawm 0.2nm txog 1.2nm. Yog li, CWDM hu ua sparse wavelength division multiplexing technology nrog rau kev hwm DWDM.
2. DWDM yog dab tsi thiab qhov zoo?
DWDM yog qhov sib faib nthwv sib cais sib faib sib npaug, nrog cov kab nrig dav (0.4nm lossis 0.8nm), cov kem ntau ntawm cov channel, thiab cov kev cai siab. Nws yog tsuas yog siv nyob rau sab kab, thiab hauv zos network thiab nroog cheeb tsam network tseem siv dav. Cov tib tshooj channel muaj qhov kis tau tus mob siab thiab lub zog loj zog.
Cov txiaj ntsig zoo: DWDM optical module tau me me thiab yuav tsum tau siv cov khoom siv hluav taws xob tswj qhov ntev ntxiv. Nws lub ntsiab kom zoo dua yog tias nws yog qhov kev daws teeb meem zoo tshaj plaws los daws teeb meem kab bandwidth nthuav.
3. CWDM yog dab tsi?
CWDM yog coarse wavelength faib multiplexing, nrog qhov dav dav dav (20nm) thiab qee qhov me me (16 raws hauv channel qhov dav ntawm 1200 txog 1700nm). Cov txuj ci qis qis, feem ntau yog siv hauv kev nkag mus sib txuas ntawm nroog thaj tsam network. Tib tshooj kis tau tus mob tsuas yog tsawg thiab qhov kev ua haujlwm ntawm lub system tsis loj.
4. CCWDM yog dab tsi thiab qhov zoo?
CCWDM yog cov kev faib tawm me sib faib, sib faib me me ntawm CWDM. Qhov loj ntawm CWDM pob yog qhov yooj yim 110 × 80 × 12mm.
Hauv kev sib piv, CCWDM muaj ntau lub pob me dua. Cov vev xaib sib txuas ntawm CCWDM siv cov kab nrig sib txuas rau cov chaw tso hauv qhov chaw kom tsis txhob muaj cov fiber ntau. Tsis muaj cov fiber ntau siv rau cascading, CCWDM pob tsuas yog 41 x 28 x 8.7 mm3, uas yog 10 npaug me dua cov qauv CWDM pob.
Cov txiaj ntsig zoo: Cov cuab yeej thiab cov txheej txheem ruaj khov, txo tus nqi tsim khoom, pob khoom me me loj, ua kom loj dua (4/8/10 lossis ntau qhov kev tso tawm), cov ntaub ntawv sib txuas lus network / telecom network rau tus nqi qis tsis-txias laser tshuab.
5. Qhov twg yog qhov zoo dua rau CWDM optical modules, DWDM optical modules, thiab CCWDM modules?
Los ntawm cov nqi kev xam pom, CCWDM yog pheej yig dua CWDM thiab DWDM. CWDM optical modules muab cov kev daws teeb meem yooj yim thiab raug nyiaj tsawg rau kev lees txais Gigabit Ethernet thiab Fiber Channel. CCWDM txais yuav cov ntaub ntawv kev sib txuas lus network / telecom network kom haum rau cov cuab yeej siv qis laser tsis muaj txiaj ntsig los ntawm kev siv cov kev sib txuas lus kho qhov muag, cov nqi tsim nqi tsawg, pob khoom me me thiab qhov loj dua (4/8/10 lossis ntau tshaj). Ntawm qhov tod tes, DWDMs feem ntau siv denser channel spacing thiab yog siv rau cov qhov muag loj dua kev sib koom tes ntawm cov chaw nyob deb.
