I-Space division multiplexing (SDM) ubuchwepheshe obusebenzisa ukuhlukaniswa kwendawo ukuze kusetshenziswe kabusha. Njengoba inani elikhulayo lokukhiqizwa kwedatha kanye nezidingo ezikhulayo zomthamo wokudlulisa i-optical fiber, ukuthuthukiswa kobukhulu obukhulu sekufinyelele esicongweni futhi akusakwazi ukwenza intuthuko. Ubuchwepheshe be-Space division multiplexing bube yindlela ebalulekile yocwaningo yokuthuthukisa umthamo wayo wokudlulisa. I-Space division multiplexing optical fiber yenziwa ku-optical fiber eyodwa ngokusebenzisa isimiso se-multi-dimensional multiplexing sesikhala nemodi. Ngokwethiyori, ingandisa umthamo wokudlulisa we-optical fiber ngokulandelana okukhulu, okulindeleke ukuthi kuxazululwe inkinga yamandla okudlulisa idatha.
Ngokwesimo sesikhathi solwazi, idatha enkulu, ukubalwa kwamafu, ubuhlakani bokwenziwa, i-inthanethi yezinto, i-5g kanye nezinye izimboni zithuthuka ngokushesha, futhi ukukhula komnotho wedijithali kuyamangalisa, kodwa futhi kuletha ukwanda okusheshayo kokukhiqizwa kwedatha. Ngokusho kwedatha ye-statista, inhlangano enegunya lomhlaba wonke, kulinganiselwa ukuthi ngo-2035, ukukhiqizwa kwedatha yomhlaba wonke kuzofinyelela ku-2142ZB, kungena esigabeni sokukhula okukhulu. Kulesi simo, ingcindezi yokudluliselwa kwenethiwekhi izokhula ngokushesha, futhi izidingo zomthamo wokudluliselwa kwe-optical fiber zizoqhubeka nokuthuthuka. Ucwaningo lwe-space division multiplexing optical fiber ludonsele ukunaka, futhi imakethe izoletha amathuba okuthuthukiswa.
I-Space division multiplexing optical fiber ikakhulukazi ihlanganisa i-core multiplexing optical fiber kanye ne-mode multiplexing optical fiber. Umkhiqizo omele owokuqala yi-multi-core optical fiber, etholakala ngokungeza ama-core amaningi e-single-mode ku-fiber eyodwa ye-optical, kanti umkhiqizo omele owokugcina yi-few mode optical fiber, etholakala ngokwandisa inani lezindlela zokudlulisa ku-core eyodwa. Zombili zinezinzuzo nezinkinga zazo. I-multi-core few mode fiber, ehlanganisa ubuchwepheshe be-multi-core fiber kanye ne-few mode fiber, ingahlanganisa izinzuzo zalezi ezimbili futhi ithuthukise kakhulu amandla okudlulisa i-optical fiber. Sekuyisiqondiso esibalulekile socwaningo lwe-space division multiplexing fiber.
