How do fiber optic cables work？

Zisebenza njani iintambo zefiber optic? Le yingxaki abantu abaninzi abanokudibana nayo xa besebenzisa i-Intanethi kunye nobunye ubuchwephesha obuxhomekeke kuthungelwano lwefiber optic. Iintambo zeFiber optic ziyinxalenye ebalulekileyo yonxibelelwano lwanamhlanje kunye neenkqubo zokuhambisa idatha. Ezi ntambo zenziwe ngeglasi encinci okanye iingcingo zeplastiki ezisebenzisa ukukhanya ukuhambisa idatha ngesantya esiphezulu kakhulu.

Iintambo ze-intanethi ze-Fiber optic yenye yezona zinto zixhaphakileyo ze-fiber optic cables. Ezi ntambo zenzelwe ukuthwala idatha ye-intanethi ngesantya esikhawuleza kakhulu kuneentambo zobhedu zemveli. Oku kuphunyezwa ngokusebenzisa i-pulses yokukhanya ehamba ngeentambo ze-fiber optic, ezivumela amazinga aphezulu okudluliselwa kwedatha. Iindibano ze-fiber optic cable ezipheliswe kwangaphambili ziya zithandwa kakhulu kuba zibonelela ngendlela efanelekileyo nesebenzayo yokufaka intambo yefiber optic kwiindawo ezahlukeneyo. Ezi ntambo zefiber optic premade ziyafumaneka kwiindidi ezahlukeneyo ezifanangaphakathikwayeiintambo zangaphandlekwaye zilungele ukusetyenziswa kanye ngaphandle kwebhokisi.

Ke, zisebenza njani kanye kanye iintambo zefiber optic? Inkqubo iqala ngokuhambisa idatha ngendlela ye-pulses yokukhanya. Ezi pulse zilula ziveliswa zizixhobo ezibizwa ngokuba zii-laser diodes, ezikwaziyo ukukhupha ukukhanya kobude obuthile. I-pulse yokukhanya ke idlula kumbindi wentambo, ejikelezwe yinto enesalathisi esisezantsi esibizwa ngokuba yi-cladding. Olu lungelelwaniso luvumela ii-pulses ezikhanyayo ukuba zibonise kwiindonga ezingundoqo zentambo, ngokufanelekileyo "ukubonisa" ukukhanya kubuyele kwintambo. Le nkqubo, ebizwa ngokuba yi-total internal reflection, ivumela ii-pulse ezikhanyayo ukuba zihambe imigama emide ngaphandle kokulahlekelwa ngamandla.

Xa kuziwa ekudibaniseni iintambo zefiber optic, inkqubo ilula ngokufanelekileyo. Ukudibanisa kubandakanya ukudibanisa iintambo ezimbini zefiber optic kunye ukwenza umgca wothumelo oqhubekayo. Oku kunokwenziwa kusetyenziswa iindlela ezahlukeneyo zobuchule, kubandakanywa ukudibanisa ngoomatshini. Ukudibanisa kubandakanya ukusebenzisa umatshini ukulungelelanisa iziphelo zeentambo ezimbini uze usebenzise i-arc yombane ukuzidibanisa. Ukwahlulahlula koomatshini, kwelinye icala, kusebenzisa iziqhagamshelo ezikhethekileyo ukudibanisa iintambo ngaphandle kwesidingo sokudityaniswa.

Ukuqukumbela, iintambo zefiber optic ziyinxalenye ebalulekileyo yonxibelelwano lwangoku kunye neenkqubo zokuhambisa idatha. Kwa oyi, sinebhongo ngokunikezela ngoluhlu olubanzi lweentlobo ze-fiber optic cable, kubandakanywa iintambo zefayibha optic ezisele zenziwe, eziyilelwe ukuhlangabezana neemfuno ezahlukeneyo zabathengi bethu. Iintambo zethu zefiber optic azikhawulezi kwaye zithembeke ngakumbi kuphela, zomelele kwaye azibizi kakhulu. Ngeenkqubo zokuvelisa eziphucukileyo, siyakwazi ukuvelisa iintambo zefiber optic ezizezona ziphambili kubuchwephesha, siqinisekisa ukuba abathengi bethu bafumana ezona mveliso zibalaseleyo.
