Nrog rau kev loj hlob sai ntawm kev txawj ntse ntawm cov cuab yeej siv (AI) thev naus laus zis, qhov kev thov rau kev ua cov ntaub ntawv thiab kev sib txuas lus tau mus txog qhov ntsuas tsis tau muaj dua. Tshwj xeeb tshaj yog nyob rau hauv cov teb xws li kev tshuaj xyuas cov ntaub ntawv loj, kev kawm tob, thiab kev suav huab, cov kab ke sib txuas lus muaj kev xav tau siab rau kev ceev ceev thiab bandwidth siab. Ib txwm muaj ib hom fiber ntau (SMF) raug cuam tshuam los ntawm qhov txwv nonlinear Shannon, thiab nws lub peev xwm kis tau yuav ncav cuag nws qhov txwv siab tshaj plaws. Spatial Division Multiplexing (SDM) kev sib kis thev naus laus zis, sawv cev los ntawm ntau lub hauv paus fiber (MCF), tau siv dav hauv cov tes hauj lwm sib txuas lus ntev thiab cov tes hauj lwm nkag mus rau lub teeb luv luv, txhim kho qhov muaj peev xwm kis tau tag nrho ntawm lub network.
Cov fiber ntau lub hauv paus ua rau cov kev txwv ntawm cov fiber ib hom ib txwm muaj los ntawm kev koom ua ke ntau lub hauv paus fiber ywj pheej rau hauv ib lub fiber, ua rau muaj peev xwm kis tau ntau dua. Ib lub fiber ntau lub hauv paus ib txwm muaj plaub txog yim lub hauv paus fiber ib hom uas sib npaug zos hauv lub hnab tiv thaiv nrog txoj kab uas hla ntawm kwv yees li 125um, ua rau muaj peev xwm bandwidth tag nrho tsis nce txoj kab uas hla sab nraud, muab kev daws teeb meem zoo tshaj plaws los ua kom tau raws li kev loj hlob ntawm kev sib txuas lus hauv kev txawj ntse.
Daim ntawv thov ntawm ntau lub fiber ntau lub cev xav tau kev daws teeb meem xws li kev sib txuas ntawm ntau lub fiber ntau thiab kev sib txuas ntawm ntau lub fiber ntau thiab cov fiber ib txwm muaj. Nws yog qhov tsim nyog los tsim cov khoom siv sib txuas xws li MCF fiber connectors, kiv cua hauv thiab kiv cua tawm rau MCF-SCF hloov pauv, thiab xav txog kev sib raug zoo thiab kev siv tau thoob ntiaj teb nrog cov thev naus laus zis uas twb muaj lawm thiab kev lag luam.
Cov tub ntxhais fiber ntau lub kiv cua hauv / kiv cua tawm
Yuav ua li cas txuas cov fiber ntau lub hauv paus nrog cov fiber ntau lub hauv paus ib txwm muaj? Cov khoom siv fiber ntau lub hauv paus kiv cua hauv thiab kiv cua tawm (FIFO) yog cov khoom tseem ceeb rau kev ua tiav kev sib txuas zoo ntawm cov fiber ntau lub hauv paus thiab cov fiber ntau hom txheem. Tam sim no, muaj ntau yam thev naus laus zis rau kev siv cov khoom siv fiber ntau lub hauv paus kiv cua hauv thiab kiv cua tawm: fused tapered technology, bundle fiber bundle method, 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 ntau yam kev siv.
Cov tub ntxhais fiber ntau MCF fiber optic connector
Qhov teeb meem kev sib txuas ntawm ntau lub core optical fibers thiab ib lub core optical fibers tau daws lawm, tab sis kev sib txuas ntawm ntau lub core optical fibers tseem yuav tsum tau daws. Tam sim no, ntau lub core optical fibers feem ntau txuas nrog los ntawm fusion splicing, tab sis txoj kev no kuj muaj qee qhov kev txwv, xws li kev nyuaj siab hauv kev tsim kho thiab kev saib xyuas nyuaj hauv theem tom qab. Tam sim no, tsis muaj tus qauv sib koom ua ke rau kev tsim cov multi-core optical fibers. Txhua tus neeg tsim khoom tsim cov multi-core optical fibers nrog cov kev npaj sib txawv, qhov loj me, qhov sib nrug ntawm lub core, thiab lwm yam, uas ua rau muaj kev nyuaj ntawm fusion splicing ntawm ntau lub core optical fibers.
Multi core fiber MCF Hybrid module (siv rau EDFA optical amplifier system)
Hauv qhov Space Division Multiplexing (SDM) optical transmission system, qhov tseem ceeb rau kev ua tiav qhov muaj peev xwm siab, ceev ceev, thiab kev sib kis mus ntev yog nyob rau hauv kev them nyiaj rau qhov poob ntawm cov teeb liab hauv cov fibers optical, thiab cov amplifiers optical yog cov khoom tseem ceeb hauv cov txheej txheem no. Raws li lub zog tseem ceeb rau kev siv SDM technology, kev ua tau zoo ntawm SDM fiber amplifiers ncaj qha txiav txim siab qhov ua tau ntawm tag nrho lub system. Ntawm lawv, ntau-core erbium-doped fiber amplifier (MC-EFA) tau dhau los ua qhov tseem ceeb tsis tseem ceeb hauv SDM transmission systems.
Ib qho EDFA system feem ntau yog tsim los ntawm cov khoom tseem ceeb xws li erbium-doped fiber (EDF), lub teeb twj tso kua mis, coupler, isolator, thiab optical filter. Hauv MC-EFA systems, txhawm rau kom ua tiav kev hloov pauv zoo ntawm ntau-core fiber (MCF) thiab ib lub tub ntxhais fiber (SCF), lub system feem ntau qhia txog Fan in/Fan out (FIFO) devices. Yav tom ntej multi-core fiber EDFA kev daws teeb meem yuav tsum tau ncaj qha koom ua ke MCF-SCF hloov pauv kev ua haujlwm rau hauv cov khoom siv optical (xws li 980/1550 WDM, nce flattening filter GFF), yog li ua kom yooj yim rau lub system architecture thiab txhim kho kev ua tau zoo tag nrho.
Nrog kev txhim kho tas mus li ntawm SDM thev naus laus zis, MCF Hybrid Cheebtsam yuav muab cov kev daws teeb meem amplifier zoo dua thiab poob qis rau yav tom ntej cov kab ke sib txuas lus optical muaj peev xwm siab.
Hauv cov ntsiab lus no, HYC tau tsim cov khoom sib txuas fiber optic MCF tshwj xeeb uas tsim los rau kev sib txuas fiber optic ntau lub hauv paus, nrog peb hom interface: LC hom, FC hom, thiab MC hom. Cov khoom sib txuas LC hom thiab FC hom MCF ntau lub hauv paus fiber optic tau raug hloov kho thiab tsim raws li cov khoom sib txuas LC / FC ib txwm muaj, ua kom zoo dua qhov chaw thiab kev khaws cia, txhim kho cov txheej txheem sib tsoo, xyuas kom meej tias muaj kev hloov pauv tsawg kawg nkaus hauv kev poob tom qab ntau qhov sib txuas, thiab hloov ncaj qha cov txheej txheem fusion splicing kim kom ntseeg tau tias yooj yim siv. Tsis tas li ntawd, Yiyuantong kuj tau tsim cov khoom sib txuas MC tshwj xeeb, uas muaj qhov me dua li cov khoom sib txuas interface ib txwm muaj thiab tuaj yeem siv rau qhov chaw ntom ntom dua.
