Nrog rau kev txhim kho sai ntawm kev txawj ntse txawj ntse (AI) thev naus laus zis, qhov kev thov rau kev ua cov ntaub ntawv thiab kev sib txuas lus muaj peev xwm tau mus txog qhov ntsuas tsis tau pom dua. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li kev tsom xam cov ntaub ntawv loj, kev kawm tob, thiab kev suav huab, kev sib txuas lus tau nce siab ntxiv rau kev kub ceev thiab siab bandwidth. Kev lig kev cai ib hom fiber ntau (SMF) cuam tshuam los ntawm kev txwv tsis pub siv Shannon, thiab nws lub peev xwm kis tau mus txog nws qhov kev txwv siab. Spatial Division Multiplexing (SDM) kis tau tus mob thev naus laus zis, sawv cev los ntawm ntau cov tub ntxhais fiber ntau (MCF), tau siv dav hauv kev sib txuas lus sib txuas mus ntev thiab kev sib txuas lus luv luv, ua kom muaj peev xwm kis tau tus mob ntawm lub network.
Ntau cov tub ntxhais kho qhov muag fibers tawg los ntawm cov kev txwv ntawm cov tsoos ib hom fibers los ntawm kev sib koom ua ke ntau cov fiber ntau ywj siab rau hauv ib qho fiber ntau, ua kom muaj peev xwm sib kis tau zoo. Ib qho tseem ceeb ntawm cov tub ntxhais fiber ntau yuav muaj plaub mus rau yim hom fiber ntau cores sib npaug sib npaug hauv cov ntaub thaiv npog nrog txoj kab uas hla ntawm kwv yees li 125um, ua kom muaj peev xwm ua kom muaj peev xwm tag nrho bandwidth yam tsis tau nce txoj kab nruab nrab, muab cov kev daws teeb meem zoo tshaj plaws kom tau raws li kev loj hlob ntawm kev sib txuas lus xav tau hauv kev txawj ntse ntse.
Daim ntawv thov ntawm multi-core optical fibers yuav tsum tau daws ib tug series ntawm cov teeb meem xws li multi-core fiber kev twb kev txuas thiab kev sib txuas ntawm multi-core fibers thiab tsoos fibers. Nws yog ib qho tsim nyog los tsim cov khoom sib txuas nrog cov khoom siv xws li MCF fiber ntau connectors, kiv cua hauv thiab kiv cua tawm cov khoom siv rau kev hloov dua siab tshiab ntawm MCF-SCF, thiab xav txog kev sib raug zoo thiab kev sib raug zoo nrog cov khoom lag luam uas twb muaj lawm thiab kev lag luam.
Multi core fiber ntxuam hauv / kiv cua tawm ntaus ntawv
Yuav ua li cas txuas multi-core optical fibers nrog ib txwm core optical fibers? Multi core fiber ntxuam hauv thiab kiv cua tawm (FIFO) cov khoom siv yog cov khoom siv tseem ceeb rau kev ua tiav kev sib txuas ntawm ntau cov tub ntxhais fibers thiab cov qauv ib hom fibers. Tam sim no, muaj ntau yam thev naus laus zis rau kev siv ntau cov tub ntxhais fiber ntau kiv cua hauv thiab kiv cua tawm cov khoom siv: fused tapered technology, bundle fiber ntau txoj kev, 3D waveguide technology, thiab space optics technology. Cov txheej txheem saum toj no txhua tus muaj lawv tus kheej qhov zoo thiab tsim nyog rau cov xwm txheej sib txawv.
Multi-core fiber ntau MCF fiber ntau optic connector
Qhov teeb meem kev sib txuas ntawm cov tub ntxhais fiber ntau optical fibers thiab ib leeg tub ntxhais kho qhov muag fibers tau raug daws, tab sis kev sib txuas ntawm ntau cov tub ntxhais kho qhov muag fibers tseem yuav tsum tau daws. Tam sim no, multi-core optical fibers feem ntau txuas nrog fusion splicing, tab sis txoj kev no kuj muaj qee qhov kev txwv, xws li kev tsim kho siab thiab kev tu vaj tse nyuaj nyob rau theem tom ntej. Tam sim no, tsis muaj ib qho kev sib koom ua ke rau kev tsim cov khoom siv kho qhov muag fiber ntau. Txhua lub chaw tsim khoom tsim cov tub ntxhais kho qhov muag fiber ntau nrog cov txheej txheem sib txawv, cov tub ntxhais qhov ntau thiab tsawg, qhov sib txawv ntawm cov tub ntxhais, thiab lwm yam, uas ua rau pom qhov nyuaj ntawm kev sib txuas ntawm cov tub ntxhais fiber ntau optical fibers.
Multi core fiber ntau MCF Hybrid module (applied to EDFA optical amplifier system)
Nyob rau hauv qhov chaw Division Multiplexing (SDM) kho qhov muag kis tau tus mob, tus yuam sij kom ua tiav high-muaj peev xwm, high-ceev, thiab ntev kis tau tus mob nyob rau hauv compensating rau cov kis tau tus mob poob ntawm cov teeb liab nyob rau hauv optical fibers, thiab kho qhov muag amplifiers yog ib qho tseem ceeb core Cheebtsam hauv cov txheej txheem no. Raws li lub zog tsav tsheb tseem ceeb rau kev siv thev naus laus zis SDM, kev ua haujlwm ntawm SDM fiber ntau amplifiers ncaj qha txiav txim siab qhov ua tau ntawm tag nrho cov kab ke. Ntawm lawv, multi-core erbium-doped fiber amplifier (MC-EFA) tau dhau los ua ib qho tseem ceeb ntawm cov khoom siv hauv SDM kis tau tus mob.
Ib qho EDFA system feem ntau yog tsim los ntawm cov khoom tseem ceeb xws li erbium-doped fiber (EDF), twj tso kua mis lub teeb, coupler, cais, thiab cov lim dej. Hauv MC-EFA systems, txhawm rau ua kom tau txais kev hloov pauv tau zoo ntawm ntau cov tub ntxhais fiber ntau (MCF) thiab ib leeg tub ntxhais fiber ntau (SCF), lub kaw lus feem ntau qhia Ntxuam hauv / Ntxuam tawm (FIFO) cov khoom siv. Lub neej yav tom ntej multi-core fiber ntau EDFA cov tshuaj yuav tsum tau ncaj qha koom ua ke MCF-SCF hloov dua siab tshiab ua haujlwm rau hauv cov khoom siv kho qhov muag (xws li 980/1550 WDM, nce flattening filter GFF), yog li ua kom yooj yim rau cov txheej txheem architecture thiab txhim kho kev ua haujlwm tag nrho.
Nrog rau kev txhim kho txuas ntxiv ntawm SDM thev naus laus zis, MCF Hybrid Cheebtsam yuav muab cov kev daws teeb meem zoo dua thiab tsis tshua muaj kev cuam tshuam rau yav tom ntej muaj peev xwm kho qhov muag sib txuas lus.
Nyob rau hauv cov ntsiab lus no, HYC tau tsim MCF fiber optic connectors tshwj xeeb uas tsim los rau multi-core fiber optic kev sib txuas, nrog peb hom interface: LC hom, FC hom, thiab MC hom. Hom LC thiab FC hom MCF fiber ntau optic connectors tau raug hloov kho ib nrab thiab tsim raws li ib txwm LC / FC connectors, optimizing qhov chaw thiab tuav muaj nuj nqi, txhim kho txoj kev sib tsoo coupling, xyuas kom meej qhov tsawg kawg nkaus kev hloov ntawm insertion poob tom qab ntau yam couplings, thiab ncaj qha hloov fusion splicing txheej txheem kom yooj yim ntawm kev siv. Tsis tas li ntawd, Yiyuantong kuj tau tsim ib lub MC txuas txuas, uas muaj qhov me me dua li cov khoom sib txuas ib txwm siv thiab tuaj yeem siv rau ntau qhov chaw ntom ntom.
