CWDM optical module yog dab tsi

Nrog rau kev txhim kho ntawm kev sib txuas lus kho qhov muag, cov khoom sib txuas lus kho qhov muag kuj tseem loj hlob sai.Raws li ib feem ntawm kev sib txuas lus kho qhov muag, qhov kho qhov muag module plays lub luag hauj lwm ntawm photoelectric hloov dua siab tshiab.Muaj ntau hom kev kho qhov muag modules, cov uas muaj xws li QSFP28 optical module, SFP optical module, QSFP + optical module, CXP optical module, CWDM optical module, DWDM optical module thiab hais txog.Txhua qhov kho qhov muag module muaj qhov sib txawv daim ntawv thov scenarios thiab ua haujlwm.Tam sim no kuv yuav qhia koj txog CWDM optical module.

CWDM yog tus nqi qis WDM kis tau tus mob thev naus laus zis rau txheej txheej nkag ntawm thaj chaw hauv nroog.Nyob rau hauv txoj cai, CWDM yog siv ib qho optical multiplexer rau multiplex optical signals ntawm txawv wavelengths rau hauv ib qho fiber ntau optical rau kev sib kis.teeb liab, txuas mus rau cov khoom siv tau txais.

Yog li, CWDM optical module yog dab tsi?

CWDM optical module yog optical module siv CWDM thev naus laus zis, uas yog siv los paub txog kev sib txuas ntawm cov khoom siv network uas twb muaj lawm thiab CWDM multiplexer / demultiplexer.Thaum siv nrog CWDM multiplexers / demultiplexers, CWDM optical modules tuaj yeem ua kom muaj peev xwm hauv lub network los ntawm kev xa ntau cov ntaub ntawv raws nrog nyias qhov muag wavelengths (1270nm txog 1610nm) ntawm tib lub fiber ntau.

Dab tsi yog qhov zoo ntawm CWDM?

Qhov txiaj ntsig tseem ceeb tshaj plaws ntawm CWDM yog cov khoom siv qis.Tsis tas li ntawd, lwm qhov zoo ntawm CWDM yog tias nws tuaj yeem txo cov nqi khiav lag luam ntawm lub network.Vim qhov me me, kev siv hluav taws xob tsawg, kev saib xyuas yooj yim thiab yooj yim zog ntawm cov khoom siv CWDM, 220V AC fais fab mov tuaj yeem siv tau.Vim muaj tsawg tus wavelengths, lub peev xwm thaub qab ntawm lub rooj tsavxwm yog me me.Cov khoom siv CWDM siv 8 nthwv dej tsis muaj qhov tshwj xeeb ntawm cov khoom siv kho qhov muag, thiab G.652, G.653, thiab G.655 optical fibers tuaj yeem siv tau, thiab cov khoom siv kho qhov muag uas twb muaj lawm tuaj yeem siv tau.CWDM system tuaj yeem ua kom muaj peev xwm kis tau tus mob ntawm fiber ntau thiab txhim kho kev siv cov khoom siv kho qhov muag.Kev tsim kho ntawm thaj chaw hauv nroog tau ntsib nrog qee qhov kev tsis txaus ntawm cov khoom siv kho qhov muag lossis cov nqi siab ntawm cov khoom siv kho qhov muag.Tam sim no, ib tug raug coarse wavelength division multiplexing system muaj peev xwm muab 8 optical channels, thiab tuaj yeem ncav cuag 18 optical channels ntawm feem ntau raws li G.694.2 specification ntawm ITU-T.

Lwm qhov zoo ntawm CWDM yog nws qhov me me thiab siv hluav taws xob tsawg.Lub lasers hauv CWDM system tsis xav tau semiconductor tub yees thiab tswj qhov kub thiab txias, yog li kev siv hluav taws xob tuaj yeem txo qis.Piv txwv li, txhua lub laser hauv DWDM system siv li 4W ntawm lub zog, thaum lub CWDM laser tsis muaj qhov txias tsuas yog siv 0.5W ntawm lub zog.Lub simplified laser module nyob rau hauv lub CWDM system txo qhov ntim ntawm kev sib xyaw optical transceiver module, thiab qhov yooj yim ntawm cov khoom siv kuj txo qhov ntim ntawm cov cuab yeej thiab txuag qhov chaw hauv chav tsev khoom.

Dab tsi yog hom CWDM optical modules?

(1) CWDM SFP optical module

CWDMSFP optical module yog ib qho khoom siv kho qhov muag uas ua ke nrog CWDM thev naus laus zis.Zoo ib yam li cov tsoos SFP, CWDM SFP optical module yog qhov kub-swappable input / output ntaus ntawv tso rau hauv SFP chaw nres nkoj ntawm qhov hloov lossis router, thiab txuas nrog lub network fiber ntau los ntawm qhov chaw nres nkoj no.Nws yog ib qho kev lag luam zoo thiab muaj txiaj ntsig kev sib txuas hauv kev sib txuas lus siv dav hauv kev siv network xws li Gigabit Ethernet thiab Fiber Channel (FC) hauv tsev kawm ntawv, cov chaw zov me nyuam, thiab cov chaw hauv nroog loj.

(2) CWDM GBIC (Gigabit Interface Converter)

GBIC yog qhov kub-swappable input / output ntaus ntawv uas ntsaws rau hauv Gigabit Ethernet chaw nres nkoj lossis qhov qhib kom ua tiav kev sib txuas network.GBIC kuj yog tus qauv transceiver, feem ntau yog siv ua ke nrog Gigabit Ethernet thiab Fiber Channel, thiab feem ntau yog siv hauv Gigabit Ethernet keyboards thiab routers.Ib qho yooj yim hloov kho los ntawm tus qauv LH, siv DFB lasers nrog cov wavelengths tshwj xeeb, txhawb kev txhim kho ntawm CWDM GBIC optical modules thiab DWDM GBIC optical modules.GBIC optical modules feem ntau yog siv rau Gigabit Ethernet optical fiber kis tau tus mob, tab sis lawv kuj tau koom nrog qee qhov xwm txheej, xws li kho qhov muag fiber ntau network txo qis, ua kom nrawm thiab ntau daim ntawv thov kev sib kis nyob ib puag ncig 2.5Gbps.

GBIC optical module yog kub-swappable.Cov yam ntxwv no, ua ke nrog cov qauv tsim ntawm lub tsev, ua rau nws muaj peev xwm hloov tau los ntawm ib hom kev sib txuas sab nraud mus rau lwm hom kev sib txuas los ntawm tsuas yog ntxig rau GBIC optical module.Feem ntau, GBIC feem ntau siv ua ke nrog SC interface connectors.
