Ndi chitukuko chofulumira chaukadaulo waukadaulo wa Artificial Intelligence (AI), kufunikira kwa ma data processing ndi kulumikizana kwafika pamlingo womwe sunachitikepo. Makamaka m'magawo monga kusanthula kwakukulu kwa data, kuphunzira mozama, ndi makina apakompyuta, njira zoyankhulirana zimakhala ndi zofunika kwambiri pa liwiro lalikulu komanso bandwidth yayikulu. Traditional single-mode fiber (SMF) imakhudzidwa ndi malire osagwirizana ndi Shannon, ndipo mphamvu yake yotumizira idzafika malire ake apamwamba. Ukadaulo wopatsirana wa Spatial Division Multiplexing (SDM), womwe umaimiridwa ndi ma multi-core fiber (MCF), wagwiritsidwa ntchito kwambiri pamakina opatsirana otalikirana komanso ma netiweki afupikitsa owoneka bwino, kuwongolera kwambiri mphamvu yotumizira maukonde.
Ma Multi core Optical fibers amadutsa malire a ulusi wamtundu umodzi wamtundu umodzi pophatikiza mitundu ingapo yodziyimira payokha kukhala ulusi umodzi, ndikuwonjezera mphamvu yotumizira. Ulusi wamtundu wamitundu yambiri utha kukhala ndi zida zinayi mpaka zisanu ndi zitatu zamtundu umodzi wogawika m'chimake chotchinga chokhala ndi mainchesi pafupifupi 125um, kupititsa patsogolo kuthekera konse kwa bandwidth popanda kukulitsa m'mimba mwake, kumapereka yankho loyenera kukwaniritsa kukula kwamphamvu kwa kulumikizana kwanzeru muluntha lochita kupanga.
Kugwiritsa ntchito ma multi-core optical fibers kumafuna kuthetsa mavuto angapo monga kulumikizana kwamitundu yambiri komanso kulumikizana pakati pa ulusi wamitundu yambiri ndi ulusi wachikhalidwe. Ndikofunikira kupanga zotumphukira zokhudzana ndi zinthu monga zolumikizira CHIKWANGWANI cha MCF, fanizira mkati ndi kutulutsa zida za kutembenuka kwa MCF-SCF, ndikuganiziranso kuyanjana ndi chilengedwe chonse ndiukadaulo womwe ulipo komanso wamalonda.
Multi core fiber fan in/fan out chipangizo
Momwe mungalumikizire ulusi wamitundu yambiri ndi ulusi wamtundu umodzi wapakatikati? Zida za Multi core fiber fan in and fan out (FIFO) ndizofunikira kwambiri kuti zitheke kulumikizana bwino pakati pa ulusi wamitundu yambiri ndi ulusi wamtundu umodzi. Pakalipano, pali matekinoloje angapo ogwiritsira ntchito zida za multi-core fiber fan ndi fan out: tekinoloje yosakanikirana, njira yamagulu a fiber bundle, ukadaulo wa 3D waveguide, ndi ukadaulo wa space Optics. Njira zomwe zili pamwambazi zonse zili ndi ubwino wake ndipo ndizoyenera zochitika zosiyanasiyana zogwiritsira ntchito.
Multi core CHIKWANGWANI MCF CHIKWANGWANI chamawonedwe cholumikizira
Vuto lolumikizana pakati pa ma multi-core optical fibers ndi single core optical fibers lathetsedwa, koma kulumikizana pakati pa ma multi-core optical fibers akuyenerabe kuthetsedwa. Pakali pano, ma multi-core optical fibers nthawi zambiri amalumikizidwa ndi fusion splicing, koma njirayi ilinso ndi zofooka zina, monga zovuta zomanga komanso zovuta kukonza pambuyo pake. Pakali pano, palibe muyezo umodzi wopangira ma multi-core optical fibers. Wopanga aliyense amapanga ulusi wowoneka bwino wamitundu yambiri wokhala ndi makonzedwe apakati osiyanasiyana, makulidwe apakati, masitayilo apakati, ndi zina zambiri, zomwe zimawonjezera kuvutikira kwa kuphatikizana pakati pa ulusi wamitundu yambiri.
Multi core fiber MCF Hybrid module (yogwiritsidwa ntchito ku EDFA Optical amplifier system)
Mu Space Division Multiplexing (SDM) optical transmission system, chinsinsi chokwaniritsira kufalikira kwapamwamba, kuthamanga kwambiri, komanso mtunda wautali ndikubwezera kutayika kwa zizindikiro muzitsulo za kuwala, ndipo amplifiers optical ndizofunikira kwambiri pa ndondomekoyi. Monga mphamvu yoyendetsera ntchito yogwiritsira ntchito teknoloji ya SDM, machitidwe a SDM fiber amplifiers amatsimikizira mwachindunji kuthekera kwa dongosolo lonse. Mwa iwo, multi-core erbium-doped fiber amplifier (MC-EFA) yakhala chinthu chofunikira kwambiri pamakina opatsirana a SDM.
Dongosolo lodziwika bwino la EDFA limapangidwa makamaka ndi zigawo zazikuluzikulu monga erbium-doped fiber (EDF), gwero la kuwala kwa pampu, coupler, isolator, ndi fyuluta ya kuwala. M'makina a MC-EFA, kuti akwaniritse kutembenuka koyenera pakati pa multi-core fiber (MCF) ndi single core fiber (SCF), dongosololi nthawi zambiri limayambitsa zida za Fan in/Fan out (FIFO). Yankho lamtsogolo lamitundu yambiri ya fiber EDFA likuyembekezeka kuphatikizira mwachindunji ntchito yotembenuka ya MCF-SCF kukhala magawo owoneka bwino (monga 980/1550 WDM, kupeza fyuluta ya GFF), potero kumathandizira kamangidwe kake ndikuwongolera magwiridwe antchito.
Ndikukula kosalekeza kwaukadaulo wa SDM, zigawo za MCF Hybrid zidzapereka njira zodziwikiratu komanso zotsika zotayika zamakina olumikizirana amtsogolo.
Munkhaniyi, HYC yapanga zolumikizira za MCF fiber optic zopangidwira ma multi-core fiber optic, okhala ndi mitundu itatu ya mawonekedwe: mtundu wa LC, mtundu wa FC, ndi mtundu wa MC. Mtundu wa LC ndi mtundu wa FC MCF multi-core fiber optic zolumikizira zasinthidwa pang'ono ndikupangidwa kutengera zolumikizira zachikhalidwe za LC/FC, kukhathamiritsa malo ndi kusungirako, kuwongolera njira yolumikizirana, kuwonetsetsa kuti kutayika kwapang'onopang'ono kutayika pambuyo pophatikizana kangapo, ndikulowetsa mwachindunji njira zophatikizira zodula kuti zitsimikizire kugwiritsa ntchito. Kuphatikiza apo, Yiyuantong adapanganso cholumikizira chodzipatulira cha MC, chomwe chili ndi kukula kocheperako kuposa zolumikizira zamtundu wachikhalidwe ndipo chitha kugwiritsidwa ntchito pamipata yowirira kwambiri.
