Vim li cas qhov pib ntawm optical module / AOC / DAC tshuab qis?
Tau kawg, nqe lus no tsis nruj, vim qee cov khoom lag luam siab, lub ntiaj teb tuaj yeem ua cov tuam txhab tsawg dua, xws li 400G optical modules. Tsis tas li ntawd, tib yam khoom, xws li 100G ib hom, thaum lub tuam txhab feem ntau tsuas yog ua tau 10km, ob peb lub tuam txhab tau ua tau 40km. Tab sis rau feem coob ntawm cov khoom lag luam paub tab, qhov thaiv kev nkag mus yog qhov tsawg tiag tiag, uas tau ua rau muaj ntau qhov kev cob qhia me me uas ob peb kaum tus neeg tuaj yeem pib lub tuam txhab modular.
Yog vim li cas rau qhov qis dua yog qhov ntawdoptical module / AOC / DACyog ib qho khoom siv kho vajtse ntshiab. Txawm hais tias muaj cov tsav tsheb ntawm MCU maub los, lawv yog cov khoom yooj yim thiab cov qauv (tau kawg, tseem muaj qhov sib txawv ntawm cov neeg muag khoom, thiab ntau qhov teeb meem sib raug zoo los ntawm qhov sib txawv). Thiab cov khoom siv tseem ceeb siv hauv cov khoom siv kho vajtse tuaj yeem tau txais los ntawm txhua tus, thiab txhua tus tuaj yeem yooj yim tau txais cov kev daws teeb meem ntawm cov tuam txhab loj loj rau kev siv thiab kev coj ua, thiab txawm tias qee tus neeg muag khoom yuav ncaj qha muab cov khoom sib txuas zoo rau cov chaw tsim khoom hauv qab. Qhov no txhais tau hais tias rau cov tuam txhab tsim khoom, ntau cov khoom lag luam paub tab, peb siv cov kev daws teeb meem zoo sib xws, thiab tsis muaj qhov pib ntau dhau. Qhov no yog qhov sib txawv ntawm cov keyboards, qhov twg txhua tus neeg muag khoom hloov pauv tau nkag mus rau tib yam zoo-tsis pub dawb CPUs thiab hloov chips, tab sis qhov sib txawv ntawm tag nrho cov qauv tsim thiab cov software nyuaj ua rau muaj qhov sib txawv loj hauv tag nrho qhov zoo thiab muaj peev xwm.
Qhov txawv li cas?
Raws li tus qauv ntawm lub teeb module muaj ntau qhov sib koom ua ke, qhov pib qis, yog li yuav tsum tsis muaj qhov sib txawv ntawm module manufacturers hauv txoj kev xav. Txawm li cas los xij, qhov tseeb yog tias muaj ntau yam teeb meem sib txawv ntawm cov qauv sib txawv thiab cov khoom siv sib txawv. Txawm tias cov qauv ntawm tib tus qauv los ntawm tib lub chaw tsim khoom tuaj yeem sib txawv ntawm tib lub cuab yeej. Muaj ntau qhov laj thawj, tab sis yog hais txog qhov yooj yim, nws yog qhov sib txawv ntawm engineering zoo thiab khoom zoo.
- Qhov zoo ntawm PCB, qhov zoo ntawm capacitive kuj, qhov ntev thiab dav ntawm cov ntiv tes golden, qhov zoo ntawm cov nplaum, thiab txawm tias qhov zoo ntawm cov kua nplaum, txhua yam cuam tshuam rau qhov zoo ntawm cov khoom, xws li voltage thiab tam sim no jitter, kub nce, yuav muaj teeb meem.
- Coupling txheej txheem sib txawv, xws li COB coupling hom, SMD coupling hom, txhua qhov chaw tsim khoom xaiv txawv, txawm tias tib lub chaw tsim khoom xaiv cov khoom sib txawv, lawv yuav ua rau muaj qhov sib txawv ntawm cov nqi, kub dissipation, kub tsis kam.
- Qhov sib txawv ntawm cov khoom siv kuaj, tus naj npawb ntawm cov cuab yeej, ntau yam, qib ntawm automation, kev nplua nuj ntawm cov khoom siv thib peb xws li hloov / server network phaib, uas tuaj yeem ua rau muaj qhov sib txawv ntawm cov txiaj ntsig thiab kev sib raug zoo.
- Qhov sib txawv ntawm R & D muaj peev xwm thiab kev tswj xyuas zoo ntawm cov tuam txhab sib txawv.
- Qhov sib txawv ntawm qhov zoo ntawm cov khoom siv hluav taws xob tau txais los ntawm cov tuam txhab sib txawv. Feem ntau hais lus, ntau dua qhov ntim khoom xa tuaj, qhov siab dua ntawm cov khoom siv hluav taws xob tau txais los ntawm cov chaw tsim khoom. Piv txwv li, tib yam10 g 80 KMlaser txawv ntawm tus kheej. Qee qhov kev nkag siab zoo tuaj yeem nyob ze rau -30dB, thaum qee qhov tsuas yog txog -24dB. Thaum muab khoom, cov neeg no ze rau -30dB yuav muab qhov tseem ceeb rau cov tuam txhab loj. Yog li ntawd, tib lub optical modules ntawm 10G thiab 80km tuaj yeem siv tau. Ntawm cov kab nrog ntau lub teeb poob, qee qhov kho qhov muag modules tuaj yeem UP, thaum lwm tus tsis tuaj yeem lossis muaj pob ntawv poob loj.
- Qhov sib txawv tiag tiag hauv kev muaj peev xwm ntawm cov tuam ntxhab feem ntau yog nyob rau hauv cov khoom lag luam siab, xws li100G / 400G modules, tshwj xeeb tshaj yog nyob deb. Feem ntau, rau cov khoom tshiab, cov tuam txhab loj yuav nqis peev hauv cov cuab yeej siv thiab kev tshawb fawb thiab kev txhim kho ua ntej kom muaj txiaj ntsig zoo ua ntej. Nyob rau hauv cov ntaub ntawv muaj peev xwm tsim tau tsawg, cov chaw tsim khoom lag luam tseem yuav muab qhov tseem ceeb rau kev muab cov chips thiab lasers rau cov tuam txhab loj. Yog li ntawd, cov tuam txhab loj feem ntau muaj tsawg kawg yog ib xyoos ua ntej ntawm cov tuam txhab me me hauv cov khoom tshiab. Rau cov khoom lag luam paub tab, feem ntau cov neeg muag khoom sib txawv tsis loj, tab sis cov neeg muag khoom siv thev naus laus zis uas cov nyuj quab yuam, tuaj yeem ua tiav ntawm qee cov ntsiab lus ntawm cov kev tsis sib xws, xws li nyob rau hauv qhov kub thiab txias, qhov voltage ntau, tau txais rhiab heev ntawm qhov tsis, xws li ib me ntsis siab dua lwm tus, qhov zoo ntawm qhov sib txawv, feem ntau siv ib puag ncig tsis tuaj yeem tawm, tab sis qhov sib txawv yog pom tseeb hauv qhov hnyav hnyav.
