Vim li cas qhov pib ntawm qhov kho qhov muag module / AOC / DAC qis?
Yog lawm, cov lus no tsis yog qhov nruj, vim tias qee cov khoom lag luam siab, lub ntiaj teb tuaj yeem ua tsawg dua cov tuam ntxhab, xws li 400G optical modules. Ntxiv rau, tib cov khoom lag luam, xws li 100G tib hom, thaum cov tuam txhab feem ntau tsuas ua tau 10km, ob peb tus neeg tsim khoom muaj peev xwm ua tau 40km. Tab sis rau feem coob ntawm cov khoom lag luam mature, qhov teeb meem nkag mus yog qhov tsawg heev, uas tau ua rau muaj cov neeg ua haujlwm sib tham me me qhov twg ob peb kaum tus neeg tuaj yeem pib lub tuam txhab modular.
Cov laj thawj rau qhov tsis tshua muaj qhov tsawg yog qhov kho qhov muag kho qhov muag / AOC / DAC yog lub hauv paus ua khoom ntshiab. Txawm hais tias muaj cov tsav tsheb ntawm MCU tus tswj hwm, lawv yog cov khoom yooj yim thiab tus qauv (tau kawg, tseem muaj qhov sib txawv ntawm cov neeg muag khoom, thiab ntau yam teeb meem sib xyaw los ntawm qhov sib txawv no). Thiab cov khoom siv tseem ceeb hauv cov khoom siv kho vajtse tuaj yeem tau los ntawm txhua tus neeg, thiab txhua tus neeg tuaj yeem yooj yim tau txais cov khoom siv kho vajtse ntawm cov tuam ntxhab loj rau kev siv thiab ua raws li, thiab txawm tias qee tus neeg muab khoom yuav ncaj qha muab cov rooj sib txuas zoo rau cov nqes hluav taws xob. Qhov no txhais tau tias rau cov qauv tsim khoom lag luam, ntau cov khoom lag luam paub tab, peb siv cov cuab yeej daws teeb meem zoo heev, thiab tsis ntau dhau ib txoj kev ntsuas. Qhov no txawv heev ntawm cov keyboards, qhov twg txhua tus hloov chaw muag khoom tau nkag mus rau tib lub zoo tsis muaj CPUs thiab hloov chips, tab sis qhov sib txawv ntawm cov txiag tsim tag nrho thiab cov software software ua rau muaj qhov sib txawv loj hauv qhov zoo thiab muaj peev xwm.
GG # 39; s qhov sib txawv li cas?
Raws li tus txheej txheem ntawm lub teeb module muaj ntau yam kev sib koom ua ke, qhov pib ntawm tsawg, yog li yuav tsum tsis muaj qhov sib txawv ntawm cov qauv tsim hluav taws xob hauv kev tshawb xav. Txawm li cas los xij, qhov kev muaj tiag 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 lub qauv los ntawm tib cov khoom lag luam tuaj yeem sib txawv ntawm tib lub cuab yeej. Muaj ntau ntau yam, tab sis yog hais txog lub ntsiab yooj yooj yim, nws yog qhov sib txawv ntawm kev tsim khoom zoo thiab cov khoom siv zoo.
• Kev ua tau zoo ntawm PCB, qhov zoo ntawm kev muaj peev xwm tiv taus, qhov ntev thiab dav ntawm ntiv tes kub, qhov zoo ntawm ham, thiab txawm tias qhov zoo ntawm kua nplaum, txhua qhov cuam tshuam rau cov khoom zoo, xws li voltage thiab jitter tam sim no, kub nce , yuav muaj teeb meem.
• Kev sib txawv tus txheej txheem sib txawv, xws li COB txuas hom, SMD txuas txuas hom, txhua lub chaw tsim khoom' s kev xaiv sib txawv, txawm tias tib lub tuam txhab' s kev xaiv ntawm cov khoom sib txawv yog txawv, lawv yuav ua rau muaj qhov sib txawv ntawm tus nqi, tshav kub dissipation, siab kub kuj.
• Cov khoom sib txawv hauv cov khoom kuaj cov khoom, tus naj npawb ntawm cov khoom siv, ntau yam, qib ntawm kev siv tshuab, kev nplua nuj ntawm cov khoom siv thib peb xws li kev hloov pauv / cov npav network network, uas tuaj yeem ua rau muaj qhov sib txawv ntawm cov txiaj ntsig thiab sib txawv.
• Cov sib txawv hauv R& D peev xwm thiab kev tswj hwm qhov zoo ntawm cov tuam ntxhab sib txawv.
• Qhov sib txawv hauv qhov ua tau zoo ntawm cov nplais hluav taws xob tau txais los ntawm cov tuam ntxhab sib txawv. Feem ntau hais lus, lub siab dua cov zaub mov xa tuaj, ntau dua qhov ua tau zoo ntawm cov khoom siv hluav taws xob sab nraud tau txais los ntawm cov chaw tsim khoom. Piv txwv li, tib 10G 80KM laser sib txawv ntawm tus kheej. Qee tus tau txais rhiab heev tuaj yeem ze rau -30dB, thaum qee tus tsuas yog yuav txog -24dB. Thaum muab khoom, cov neeg no ze -30dB yuav muab qhov muaj feem thib rau cov tuam txhab loj. Yog li ntawd, tib lub kho qhov muag ntawm 10G thiab 80km yuav siv tau. Ntawm cov kab uas muaj lub teeb nrawm dhau, qee qhov kho qhov muag kho tau tuaj yeem UP, thaum lwm tus tuaj yeem' t 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 high-end, xws li 100G / 400G modules, tshwj xeeb tshaj yog cov kev deb. Feem ntau, rau cov khoom lag luam tshiab, cov tuam ntxhab loj yuav nqis peev rau cov cuab yeej siv thiab kev tshawb fawb thiab kev txhim kho ua ntej kom khaws cov txiaj ntsig kev ua ntej. Thaum tsis tshua muaj peev xwm ntau lawm, cov tshuab hluav taws xob tseem yuav muab qhov tseem ceeb los muab cov chips thiab lasers rau cov chaw tsim khoom loj. Yog li, cov chaw tsim khoom loj feem ntau muaj tsawg kawg ib xyoos ua ntej ntawm cov tuam ntxhab me me hauv cov khoom lag luam tshiab. Rau cov khoom lag luam paub tab, feem ntau cov muag khoom sib txawv tsis loj, tab sis cov neeg muag khoom thev naus laus zis hais tias lub zog nyuj, tuaj yeem ua tiav kev ua tiav ntawm qee cov ntsiab lus ntawm cov txheej txheem thev naus laus zis, xws li nyob hauv qhov ntsuas kub, qhov ntau, tau txais kev nkag siab ntawm cov tsis xws, xws li me dua ntau dua lwm tus, qhov zoo dua ntawm qhov sib txawv, hauv kev siv dav dav ib puag ncig tsis yog qhov yuav tsum tawm, tab sis qhov sib piv yog pom tseeb hauv ib puag ncig hnyav.
