Nekukurumidza kukura kweArtificial Intelligence (AI) tekinoroji, kudiwa kwekugadziriswa kwedata uye kugona kutaurirana kwasvika pachiyero chisina kumboitika. Kunyanya muminda yakadai seyekuongorora data hombe, kudzidza kwakadzama, uye makore computing, masisitimu ekutaurirana ane kuwedzera zvakanyanya zvinodiwa zvekumhanya zvakanyanya uye yakakwirira bandwidth. Traditional single-mode fiber (SMF) inobatwa neiyo isina mutsara Shannon muganho, uye simba rekutapurirana rinosvika painogumira. Spatial Division Multiplexing (SDM) tekinoroji yekufambisa, inomiririrwa ne-multi-core fiber (MCF), yakashandiswa zvakanyanya mumatanho akareba akabatana ekutapurirana network uye mapfupi-renji optical access network, zvakanyanya kuvandudza huwandu hwese hwekutapurirana kwetiweki.
Multi core optical fibers inotyora zvipimo zvechinyakare single-mode fibers nekubatanidza akawanda akazvimirira fiber cores mune imwechete fiber, zvakanyanya kuwedzera kutapurirana. Yakajairika multi-core fiber inogona kunge iine mana kusvika masere single-mode fiber cores yakagovaniswa mune inodzivirira sheath ine dhayamita ingangoita 125um, ichiwedzera zvakanyanya bandwidth kugona pasina kuwedzera dhayamita rekunze, ichipa mhinduro yakanaka yekusangana nekuputika kukura kwekutaurirana zvinoda muhungwaru hwekugadzira.
Iko kushandiswa kwema-multi-core optical fibers kunoda kugadzirisa nhevedzano yezvinetso zvakadai se-multi-core fiber connection uye kubatana pakati pe-multi-core fibers uye tsika dzechinyakare. Izvo zvinodikanwa kugadzira zvigadzirwa zvine chekuita nechikamu seMCF fiber connectors, fan mukati uye fan out zvishandiso zveMCF-SCF shanduko, uye funga kuenderana uye Universal nearipo uye ekutengesa matekinoroji.
Multi core fiber fan in / fan kunze mudziyo
Maitiro ekubatanidza akawanda-core optical fibers ane echinyakare single core optical fibers? Multi core fiber fan in and fan out (FIFO) zvishandiso zvinhu zvakakosha zvekuwana kubatanidza pakati pe-multi-core fibers uye yakajairwa single-mode fibers. Parizvino, kune akati wandei matekinoroji ekushandisa akawanda-core fiber fan mukati uye fan out zvishandiso: fused tapered tekinoroji, bundle fiber bundle nzira, 3D waveguide tekinoroji, uye space optics tekinoroji. Nzira dziri pamusoro apa dzese dzine zvadzo zvakanakira uye dzakakodzera kune akasiyana mashandisirwo mamiriro.
Multi core fiber MCF fiber optic yekubatanidza
Dambudziko rekubatanidza pakati pe-multi-core optical fibers uye single core optical fibers rakagadziriswa, asi kubatana pakati pe-multi-core optical fibers kuchiri kuda kugadziriswa. Parizvino, ma-multi-core optical fibers anonyanya kubatanidzwa nefusion splicing, asi nzira iyi inewo zvimwe zvipimo, senge kuoma kwekuvaka kwakanyanya uye kugadzirisa kwakaoma mune inotevera nhanho. Parizvino, hapana chiyero chakabatana chekugadzirwa kwemulti-core optical fibers. Mumwe nemumwe anogadzira anogadzira akawanda-core optical fibers ane akasiyana musimboti marongero, core saizi, core spacing, nezvimwewo, izvo zvisingaonekwe zvinowedzera kuoma kwefusion splicing pakati pe-multi-core optical fibers.
Multi core fiber MCF Hybrid module (inoshandiswa kune EDFA Optical amplifier system)
MuSpace Division Multiplexing (SDM) optical transmission system, kiyi yekuwana hukuru-hukuru, kukurumidza-kumhanya, uye kureba kwekutapurirana kunogara mukubhadhara kurasikirwa kwekufambiswa kwezviratidzo mumafiber optical, uye optical amplifiers zvinhu zvakakosha zvakakosha mukuita uku. Sesimba rakakosha rekutyaira kwekushandisa kunoshanda kweSDM tekinoroji, kushanda kweSDM fiber amplifiers kunotarisisa zvakananga kugona kweiyo system yese. Pakati pavo, akawanda-core erbium-doped fiber amplifier (MC-EFA) yave chinhu chakakosha chikamu muSDM kutapurirana masisitimu.
Yakajairwa EDFA sisitimu inonyanya kuumbwa nepakati zvinhu zvakaita seerbium-doped fiber (EDF), pombi light source, coupler, isolator, uye optical sefa. Mune MC-EFA masisitimu, kuitira kuti uwane shanduko inoshanda pakati pe-multi-core fiber (MCF) uye single core fiber (SCF), sisitimu yacho inowanzo suma Fan in/Fan out (FIFO) zvishandiso. Iyo yeramangwana yakawanda-yakakosha fiber EDFA mhinduro inotarisirwa kubatanidza zvakananga MCF-SCF yekushandura basa mune zvine hukama zvinhu zvemaziso (senge 980/1550 WDM, kuwana flattening sefa GFF), nekudaro kurerutsa sisitimu yekuvaka nekuvandudza kuita kwese.
Nekuenderera mberi kwekusimudzira kweSDM tekinoroji, MCF Hybrid zvikamu zvinopa zvakanyanya kushanda uye zvakaderera kurasikirwa amplifier mhinduro kune remangwana repamusoro-chaiyo optical communication masisitimu.
Muchirevo chechinyorwa chino, HYC yakagadzira MCF faibha optic zvibatanidza zvakagadzirirwa kubatanidza ma-multi-core fiber optic, nemhando nhatu dzeinterface: LC type, FC type, uye MC type. Iyo LC mhando uye FC mhando MCF yakawanda-yakakosha fiber optic majoini akagadziridzwa zvishoma uye akagadzirwa zvichibva pane echinyakare LC/FC majoini, optimize chinzvimbo uye chekuchengetedza basa, kuvandudza kukuya kwekubatanidza maitiro, kuve nechokwadi kushoma shanduko mukurasikirwa kwekuisa mushure mekubatana kwakawanda, uye zvakananga kutsiva inodhura fusion splicing maitiro kuti ive nechokwadi chekushandisa. Pamusoro pezvo, Yiyuantong yakagadzirawo yakazvitsaurira MC yekubatanidza, iyo ine diki saizi pane yechinyakare interface mhando yekubatanidza uye inogona kuiswa kune dzakawanda nzvimbo dzakatetepa.
