Ndi chitukuko chofulumira cha ukadaulo wa luntha lochita kupanga (AI), kufunikira kwa kukonza deta ndi mphamvu yolumikizirana kwafika pamlingo wosayerekezeka. Makamaka m'magawo monga kusanthula deta yayikulu, kuphunzira kwambiri, ndi cloud computing, machitidwe olumikizirana ali ndi zofunikira kwambiri pa liwiro lapamwamba komanso bandwidth yayikulu. Ulusi wachikhalidwe wa single-mode (SMF) umakhudzidwa ndi malire a Shannon osakhala a mzere, ndipo mphamvu yake yotumizira idzafika pamlingo wake wapamwamba. Ukadaulo wotumizira wa Spatial Division Multiplexing (SDM), womwe umayimiridwa ndi ulusi wambiri (MCF), wakhala ukugwiritsidwa ntchito kwambiri m'maukonde otumizirana mauthenga akutali komanso maukonde olowera owonera afupiafupi, zomwe zimapangitsa kuti mphamvu yonse yotumizirana mauthenga ikhale yokwera kwambiri.
Ulusi wa multicore optical umadutsa malire a ulusi wachikhalidwe wa single-mode mwa kuphatikiza ma fiber cores angapo odziyimira pawokha mu ulusi umodzi, zomwe zimawonjezera mphamvu yotumizira. Ulusi wamba wa multi-core ukhoza kukhala ndi ma fiber cores anayi mpaka asanu ndi atatu a single-mode omwe amagawidwa mofanana mu chidebe choteteza chokhala ndi mainchesi pafupifupi 125um, zomwe zimapangitsa kuti bandwidth yonse ikhale yolimba popanda kuwonjezera mainchesi akunja, zomwe zimapangitsa kuti pakhale njira yabwino yokwaniritsira kukula kwa kufunika kwa kulumikizana mu luntha lochita kupanga.
Kugwiritsa ntchito ulusi wa kuwala wa multi-core kumafuna kuthetsa mavuto angapo monga kulumikizana kwa ulusi wa multi-core ndi kulumikizana pakati pa ulusi wa multi-core ndi ulusi wachikhalidwe. Ndikofunikira kupanga zinthu zokhudzana ndi zinthu zina monga zolumikizira za ulusi wa MCF, zida zolowetsa ndi kutulutsa fan kuti zisinthe MCF-SCF, ndikuganizira momwe zingakhalire zogwirizana ndi ukadaulo womwe ulipo komanso wamalonda.
Chipangizo chotulutsira/kutulutsa fan ya ma core ambiri
Kodi mungalumikize bwanji ulusi wa multi-core optical ndi ulusi wamba wa single core optical? Zipangizo za multi-core fiber fan in and fan out (FIFO) ndi zinthu zofunika kwambiri kuti pakhale kulumikizana koyenera pakati pa ulusi wa multi-core ndi ulusi wamba wa single-mode. Pakadali pano, pali ukadaulo wosiyanasiyana wogwiritsira ntchito zida za multi-core fiber fan in and fan out: ukadaulo wophatikizidwa, njira ya bundle fiber bundle, ukadaulo wa 3D waveguide, ndi ukadaulo wa space optics. Njira zomwe zili pamwambapa zili ndi zabwino zake ndipo ndizoyenera kugwiritsa ntchito zinthu zosiyanasiyana.
Cholumikizira cha fiber optic cha multicore MCF
Vuto lolumikizana pakati pa ulusi wa multi-core optical ndi ulusi umodzi wa single core optical lathetsedwa, koma kulumikizana pakati pa ulusi wa multi-core optical kukufunikabe kuthetsedwa. Pakadali pano, ulusi wa multi-core optical umalumikizidwa kwambiri ndi fusion splicing, koma njira iyi ilinso ndi zolepheretsa zina, monga kuvutika kwambiri pakupanga ndi kukonza kovuta mtsogolo. Pakadali pano, palibe muyezo wogwirizana wopanga ulusi wa multi-core optical. Wopanga aliyense amapanga ulusi wa multi-core optical wokhala ndi makonzedwe osiyanasiyana a core, kukula kwa core, malo a core, ndi zina zotero, zomwe zimapangitsa kuti kusagwirizana pakati pa ulusi wa multi-core optical kukhale kovuta.
Module ya Multicore MCF Hybrid (yogwiritsidwa ntchito pa EDFA optical amplifier system)
Mu dongosolo la Space Division Multiplexing (SDM), chinsinsi chopezera kutumiza kwamphamvu kwambiri, kuthamanga kwambiri, komanso mtunda wautali chili pakulipira kutayika kwa zizindikiro mu ulusi wa kuwala, ndipo ma amplifiers optical ndi zigawo zofunika kwambiri pankhaniyi. Monga mphamvu yofunika kwambiri yoyendetsera ukadaulo wa SDM, magwiridwe antchito a ma amplifiers a SDM fiber amatsimikizira mwachindunji kuthekera kwa dongosolo lonse. Pakati pawo, multi-core erbium-doped fiber amplifier (MC-EFA) yakhala gawo lofunikira kwambiri mu machitidwe otumizira a SDM.
Dongosolo la EDFA lodziwika bwino limapangidwa makamaka ndi zigawo zapakati monga ulusi wopangidwa ndi erbium (EDF), gwero la kuwala kwa pampu, cholumikizira, chosungunula, ndi fyuluta yowala. Mu machitidwe a MC-EFA, kuti akwaniritse kusintha koyenera pakati pa ulusi wa multi-core (MCF) ndi ulusi umodzi wa single core (SCF), dongosololi nthawi zambiri limayambitsa zida za Fan in/Fan out (FIFO). Yankho la EDFA la ulusi wa multi-core mtsogolo likuyembekezeka kuphatikiza mwachindunji ntchito yosinthira ya MCF-SCF mu zigawo zokhudzana ndi kuwala (monga 980/1550 WDM, kupeza fyuluta yosalala ya GFF), potero kupangitsa kuti kapangidwe ka dongosolo kakhale kosavuta komanso kukonza magwiridwe antchito onse.
Ndi chitukuko chopitilira cha ukadaulo wa SDM, zigawo za MCF Hybrid zipereka njira zolimbikitsira zogwira mtima komanso zotsika mtengo kwambiri zamachitidwe olumikizirana amagetsi amtsogolo omwe ali ndi mphamvu zambiri.
Pachifukwa ichi, HYC yapanga zolumikizira za MCF fiber optic zomwe zapangidwira makamaka kulumikizana kwa fiber optic yamitundu yambiri, yokhala ndi mitundu itatu yolumikizira: mtundu wa LC, mtundu wa FC, ndi mtundu wa MC. Zolumikizira za fiber optic zamtundu wa LC ndi mtundu wa FC MCF zasinthidwa pang'ono ndikupangidwa kutengera zolumikizira zachikhalidwe za LC/FC, kukonza malo ndi ntchito yosungira, kukonza njira yolumikizirana, kuonetsetsa kuti kusintha kochepa pakutayika kwa insertion pambuyo pa zolumikizira zingapo, ndikusinthira mwachindunji njira zodula zolumikizirana kuti zitsimikizire kuti kugwiritsa ntchito ndikosavuta. Kuphatikiza apo, Yiyuantong yapanganso cholumikizira cha MC chodzipereka, chomwe chili ndi kukula kocheperako kuposa zolumikizira zachikhalidwe zamtundu wa interface ndipo chingagwiritsidwe ntchito m'malo okhuthala kwambiri.
