Kev faib qhov chaw multiplexing (SDM) yog ib qho thev naus laus zis uas siv spatial segmentation los ua kom rov siv dua. Nrog rau kev nce ntxiv ntawm cov ntaub ntawv tsim thiab qhov xav tau ntawm kev xa xov fiber ntau dua, kev txhim kho ntawm feem ntau qhov ntev tau mus txog qhov siab tshaj plaws thiab tsis tuaj yeem ua tiav. Kev faib qhov chaw multiplexing thev naus laus zis tau dhau los ua qhov kev tshawb fawb tseem ceeb los txhim kho nws lub peev xwm xa xov. Space division multiplexing optical fiber yog ua los ntawm ib qho optical fiber los ntawm kev siv ntau qhov multiplexing ntawm qhov chaw thiab hom. Hauv kev xav, nws tuaj yeem ua rau lub peev xwm xa xov ntawm optical fiber ntau dua, uas xav tias yuav daws tau qhov teeb meem xa xov.
Nyob rau hauv cov ntsiab lus ntawm lub hnub nyoog cov ntaub ntawv, cov ntaub ntawv loj, kev suav huab, kev txawj ntse dag, Internet ntawm yam, 5g thiab lwm yam kev lag luam tab tom tsim kho sai, thiab kev loj hlob ntawm kev lag luam digital yog qhov ci ntsa iab, tab sis nws kuj coj kev nce sai ntawm kev tsim cov ntaub ntawv. Raws li cov ntaub ntawv ntawm statista, lub koom haum thoob ntiaj teb, nws kwv yees tias los ntawm 2035, kev tsim cov ntaub ntawv thoob ntiaj teb yuav ncav cuag 2142ZB, nkag mus rau theem kev loj hlob tawg. Hauv cov ntsiab lus no, lub siab xa xov network yuav nce sai, thiab cov kev xav tau ntawm lub peev xwm xa xov fiber ntau yuav txuas ntxiv txhim kho. Kev tshawb fawb ntawm qhov chaw faib multiplexing optical fiber tau nyiam kev mloog, thiab kev ua lag luam yuav coj mus rau hauv cov cib fim kev txhim kho.
Qhov chaw faib multiplexing optical fiber feem ntau suav nrog cov tub ntxhais multiplexing optical fiber thiab hom multiplexing optical fiber. Cov khoom sawv cev ntawm tus qub yog multi-core optical fiber, uas tau ua tiav los ntawm kev ntxiv ntau lub cores ib hom hauv ib lub optical fiber, thiab cov khoom sawv cev ntawm tus tom kawg yog ob peb hom optical fiber, uas tau ua tiav los ntawm kev nce tus naj npawb ntawm cov hom kis hauv ib lub core. Ob leeg muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Multi-core ob hom fiber, uas sib xyaw cov multi-core fiber thiab ob peb hom fiber thev naus laus zis, tuaj yeem koom ua ke qhov zoo ntawm ob qho thiab txhim kho qhov muaj peev xwm kis tau optical fiber zoo heev. Nws tau dhau los ua ib qho kev taw qhia tseem ceeb ntawm kev tshawb fawb txog qhov chaw faib multiplexing fiber.
