Ib qho transimpedance amplifier ces txhim kho qhov me me tam sim no nkag mus rau hauv cov hluav taws xob hluav taws xob koj cov cuab yeej siv tau.

Niaj hnub kev hloov pauv niaj hnub siv cov Schemes me ntsis zoo li Pam4 (Pulse qhov nrawm tau ua rau muaj ntau cov mem tes los ntawm ntau cov khoom siv thoob plaws plaub qhov sib txawv. Qhov no zoo doubles cov ntaub ntawv sib kis sib piv piv rau ib txwm muaj nyob rau ntawm- tawm cov keying yam tsis xav tau sai npaum li cas lasers lossis cov kev sib tw ntxiv.

Lub teeb taw qhia txog kev tsis txaus siab thaum lawv taug kev los ntawm fiber ntau, sib txawv (txawv waverengths tuaj txog ntawm lub sij hawm sib txawv me ntsis), thiab suab nrov thermal. Transceivers them rau cov kev tsis zoo no los ntawm ntau cov kev ua haujlwm.

Laser diodes yog rhiab heev rau qhov kev hloov pauv kub, uas ncaj qha cuam tshuam wavelength ruaj khov thiab tso zis zog. Yog tsis muaj cov kev tswj thermal thermal, cov koog no yuav ua tsis tau hauv feeb ntawm kev xa tawm.

Cov cuab yeej siv no ua cov ntse tshaj plaws nruab nrab ntawm cov cuab yeej siv thiab cov khoom siv fiber ntau. Cov cuab yeej siv feem ntau ua haujlwm ntawm kev sib txawv nrawm thiab cov qauv tshaj li uas ua rau cov neeg txhais lus.

Koj tuaj yeem ua kom zoo rau ob kab ntawv sib txuas, tab sis txhim kho txhua yam peb zaug ib zaug uas tseem muaj kev tsis haum siab vim yog muaj sia Physics thiab engineering cov kev txiav txim siab.

Cov ntaub ntawv siab dua lub ntsej muag tau tshwm sim tsis zoo nyob rau qee qhov yuam kev (ber). Lub 10g transceiver rightbyly transmits 40km dhau ib {{3} hom fiber ntau. Thawb li ntawd rau 100g, thiab koj yuav tawm tsam kom mus txog 10km tsis muaj cov cheebtsam kim xws li cov rava ravelength.

Kev xa khoom ntawm 800g chav nyob yog npaj kom nce 60% hauv 2025, tsav los ntawm Ai thiab Hyperscale cov chaw zov me nyuam. Tab sis cov ultra {{{}} high-}}} me nyuam} me nyuam} ntau dua li kev sib tw ntau dua ntawm kev ntsuas siab dua.

Kev hloov pauv nrawm dua li muaj zog ntau dua rau kev tsim khoom. Tam sim no 800g LPO chav nyob muag rau ib puag ncig $ 600, piv rau $ 500 rau multimode variants. Kev noj fais fab lus qhia cov dab neeg tiag: 10g ntaus ntawv kos 1-2 watts, thaum lub sijhawm 800g tuaj yeem haus 15-20 watts lossis ntau dua.

Nyob rau hauv ib lub chaw khaws ntaub ntawv nrog 10,000 lub chaw nres nkoj, lub zog ntawd txawv txhais rau ntau pua tus kilowatts - thiab cov lus kom txias. Lub zog siv los ntawm nws cov khoom siv yuav tsum tau 1.5 ntxiv lub zog rau cov cua txias ib leeg.

Ib qho hmoov av rau ntawm ib lub ntsej muag fiber ntau tuaj yeem thaiv 10-20% ntawm kev sib kis lub teeb, thawb tau txais hluav taws xob hauv qab no.

Fibers yog 9 microns (ib qho - hom) lossis 50-62,5 micront (multivode) hauv lub taub. Cov tsis huv me dua li tib neeg cov plaub hau tuaj yeem ua rau muaj kev puas tsuaj teeb liab. Kev txawj heev Technicians Siv kev soj ntsuam lub tshuab tsom iav nrog 200-400x magnification kom paub tseeb kev huv ua ntej kev sib txuas.

Cov ntaub ntawv cov chaw tau ntsib ntau yam teeb meem thaum muaj kev sib tw, nrog kev hloov pauv ntawm cov chaw tsim khoom sib txawv ntawm cov khoom sib txawv. Qhov no qhia txog qhov sib txawv me ntsis sib txawv hauv cov cuab yeej siv cov khoom siv hluav taws xob siv hluav taws xob thiab xa khoom hluav taws xob.

Cov cuab yeej siv no yuav tsum sib tham nrog cov khoom siv host thaum lub xeem pib. Yog tias firmware tsis teb rau cov lus nug hostries, lossis yog tias lub sijhawm ua haujlwm yog nruj, koj yuav pom kev txuas uas tsim tab sis swb tom qab feeb lossis sijhawm ua haujlwm.

Yuav tsum tau txheeb xyuas qhov sib xws nrog koj cov cuab yeej muag khoom tshwj xeeb ua ntej loj- sam hwm kev.

Vim li cas qee cov chav nyob ua tau zoo dua piv rau lwm tus?

Tus nqi sib txawv muaj kev cuam tshuam rau kev sib cais thev naus laus zis. Luv -}}}}}}}}}}}}}}} Kev siv VCSELS yuav raug nqi $ 50 {} $ 100. Ntev {{9} Taug kev coherent units them nqi $ 2,000- $ 5,000 sib xyaw ua ke ntawm cov lasps, nqaim-linewidth tunable lasers, thiab kev vam meej. Cov ntaub ntawv ntau dua tseem tsav tus nqi-800g LPO khoom siv tam sim no muag rau ntawm $ 600.

Dab tsi ua rau cov khoom siv no kom swb?

Kev ntxhov siab uas tsis muaj kev ntxhov siab los ntawm kev ua kom txias txias tsis txaus, muaj cov khoom siv ua kom tsis zoo ntawm firmware thiab cov cuab yeej tswv cuab (tshwj xeeb yog laser degradation). Qhov kev hloov kub ntau yog qhov tshwj xeeb ua kom puas rau laser diodes, cuam tshuam wavelength kev ruaj khov thiab tso zis zog.

Kuv puas xav tau tib qho kev hloov pauv ntawm ob qho kawg ntawm cov fiber ntau?

Tsis tas, tab sis ob leeg yuav tsum tau tshaj hauv cov tsis tseem ceeb. Tus nqi cov ntaub ntawv yuav tsum sib phim, thiab kis tau lub siab los ntawm ib lub cuab yeej yuav tsum poob rau hauv kev txais ntawm lwm yam. Rau Bidirectional (Bidi) Chav Nyob, koj tshwj xeeb xav tau cov neeg tawm tsam li 1310nm / tau txais 1490nm / tau txais 1310Nm.

Dab tsi yog DDM thiab vim li cas nws muaj teeb meem?

Qhov no ua rau muaj kev daws teeb meem tau ua tiav -}}}}}}}} ecining connetors (qis txais lub zog), lossis cov tshuaj tsis tshua muaj siab nyeem).

Puas yog cov khoom siv hluav taws xob kub - swappable?

Yog lawm, zoo hloov txhua yam Transceage txhawb kub - swapping {}}} ntxig thiab tshem tawm thaum cov khoom siv tseem muaj hwj chim rau. Qhov kev txhais lus no ntawm pluggable Optics pab hloov yam tsis muaj network downtime. Txawm li cas los xij, ib txwm ua raws li cov muag khoom {{}}} Cov txheej txheem tshwj xeeb kom tsis txhob muaj hluav taws xob kev puas tsuaj.

Kev nkag siab muaj nuj nqi Transforms los ntawm kev paub txog kev paub mus rau kev pom tau zoo thaum xa tawm network infrastructure. Ntawm no yog vaj tse rau cov kauj ruam tom ntej:

Yog tias koj tab tom npaj lub network hloov kho: Pib los ntawm kev nkag mus rau cov teeb meem muaj fiber ntau. Ib Leeg - hom lossis multimode? Om3, om4, lossis os2? Cov ntsiab lus no txwv koj xaiv ntau dua li cov kev qhia cov khoom siv. Xam qhov kev ncua deb ntawm - ntsuas, tsis txhob siv tus nqi tiv thaiv lossis yuav tsum tau nqis peev nyiaj siv tau ntev dua {}}}}}}} mus cuag lwm txoj kev xaiv.

Yog tias koj daws teeb meem sib txuas: Khij cov hauv paus ua ntej. Siv DDM los xyuas cov roj teeb hluav taws xob tawm hauv cov neeg tau txais kev nyab xeeb (feem ntau} 14 dbm rau luv- mus txog units). Tshawb xyuas fiber ntau lub ntsej muag nrog lub qhov muag loj-qhov muag tsis tuaj yeem pom ntau yam tsis ua haujlwm kom paug. Tshawb xyuas qhov kub nyob qis qis hauv cov rated sib tw.

Yog tias koj ntsuas cov thev naus laus zis tshiab: Tsis txhob caum tus ntug los ntshav tshwj tsis yog tias koj muaj cov kev xav tau tshwj xeeb xav tau nws. Kev hloov pauv 400 G yog qhov muaj txiaj ntsig txaus rau cov kev txhawb nqa dav dav, tab sis feem ntau cov lag luam tsis xav tau lub peev xwm rau 2-3 xyoos.

Yog tias koj txhawj txog yav tom ntej - ua pov thawj: Kev nqis peev rau cov khoom siv fiber ntau tshaj li cov kev xav tau tam sim no. Ib Leeg - hom fiber ntau ntsia hnub no yuav them nyiaj 100g, thiab dhau ntawm - lub fiber nws tus kheej tsis yog lub cottenze. Kev Hloov Pauv rau hauv cov fiber ntau tuaj yeem hloov kho nce ntxiv raws li qhov yuav tsum tau hloov kho, muab kev hloov pauv hloov tsis tas yuav ua tiav cov txheej txheem kev hloov kho.
