How do fiber optic cables work？

Zisebenza kanjani izintambo ze-fiber optic? Lena inkinga abantu abaningi abangase bahlangabezane nayo lapho besebenzisa i-inthanethi nobunye ubuchwepheshe obuthembele kumanethiwekhi e-fiber optic. Izintambo ze-fiber optic ziyingxenye ebalulekile yokuxhumana yesimanje kanye nezinhlelo zokudlulisa idatha. Lezi zintambo zenziwe ngengilazi encane noma izintambo zepulasitiki ezisebenzisa ukukhanya ukuze zidlulisele idatha ngesivinini esiphezulu kakhulu.

Izintambo ze-inthanethi ze-Fiber optic zingenye yezinhlelo ezivame kakhulu zezintambo ze-fiber optic. Lezi zintambo zenzelwe ukuthwala idatha ye-inthanethi ngesivinini esisheshayo kunezintambo zethusi zendabuko. Lokhu kufezwa ngokusebenzisa ama-pulses okukhanya ahamba ngezintambo ze-fiber optic, okuvumela amazinga aphezulu okudlulisa idatha. Amakhebula e-fiber optic anqanyuliwe ngaphambili nawo aya ngokuya aduma ngenxa yokuthi ahlinzeka ngendlela elula nephumelelayo yokufaka ikhebula le-fiber optic ezindaweni ezihlukahlukene. Lezi zintambo ze-fiber optic ezenziwe ngaphambilini zitholakala ngezinhlobo ezahlukene ezifanaendlinifuthiizintambo zangaphandlefuthi zilungele ukusetshenziswa ngaphandle kwebhokisi.

Ngakho-ke, zisebenza kanjani kahle izintambo ze-fiber optic? Inqubo iqala ngokudlulisa idatha ngesimo se-pulses yokukhanya. Lawa ma-pulses alula akhiqizwa imishini ebizwa ngokuthi ama-laser diode, akwazi ukukhipha ukukhanya kobude obuthile obuthile. I-pulse elula ibe isidlula phakathi kwentambo, ezungezwe into enenkomba ye-refractive ephansi ebizwa ngokuthi i-cladding. Lokhu kulungiselelwa kuvumela ama-pulses akhanyayo ukuthi aveze ezindongeni ze-cable core, "ibonisa" kahle ukukhanya kubuyele kukhebuli. Le nqubo, ebizwa ngokuthi i- total internal reflection, ivumela ama-pulses alula ukuba ahambe amabanga amade ngaphandle kokulahlekelwa amandla awo.

Uma kukhulunywa ngokuhlanganisa izintambo ze-fiber optic, inqubo ilula kakhulu. Ukuhlukanisa kuhlanganisa ukuhlanganisa izintambo ezimbili ze-fiber optic ndawonye ukuze zakhe ulayini wokudlulisela oqhubekayo. Lokhu kungenziwa ngokusebenzisa amasu ahlukahlukene, kuhlanganise nokuhlanganisa ngomshini. I-Fusion ihlanganisa ukusebenzisa umshini ukuqondisa iziphetho zezintambo ezimbili bese usebenzisa i-arc kagesi ukuze uwahlanganise ndawonye. I-Mechanical splicing, ngakolunye uhlangothi, isebenzisa izixhumi ezikhethekile ukuhlanganisa izintambo ngaphandle kwesidingo sokuhlanganisa.

Sengiphetha, izintambo ze-fiber optic ziyingxenye ebalulekile yokuxhumana yesimanje kanye nezinhlelo zokudlulisa idatha. Kwa-Oyi, siyaziqhenya ngokunikeza anhlobonhlobo amakhebula e-fiber optic, okuhlanganisa izintambo ze-fiber optic ezenziwe ngaphambili, eziklanyelwe ukuhlangabezana nezidingo ezihlukahlukene zamakhasimende ethu. Izintambo zethu ze-fiber optic azigcini nje ngokushesha futhi zithembeke kakhulu, futhi ziqinile futhi zingabizi kakhulu. Ngezinqubo ezithuthukisiwe zokukhiqiza, siyakwazi ukukhiqiza izintambo ze-fiber optic ezihamba phambili kwezobuchwepheshe, siqinisekisa ukuthi amakhasimende ethu athola imikhiqizo engcono kakhulu.
