Uyini umehluko phakathi kwezintambo ze-fiber optic zangaphandle nezangaphakathi?

Njengoba ubuchwepheshe buqhubeka nokuthuthuka, izidingo zabantu zamanethiwekhi ziyanda. Njengenye yezindlela ezibalulekile zokudlulisa inethiwekhi, Ikhebula le-Fiber Optics nazo zisetshenziswe kabanzi. Izinhlobo ezahlukene ze Ikhebula le-Fiber Opticziyadingeka ezimweni ezahlukene, ngaphandle nangaphakathi Ikhebula le-Fiber Optics ziyizinhlobo ezimbili ezivamile. Nakuba zombili ziyimidiya yokudlulisa izimpawu ezibonakalayo, kukhona umehluko omkhulu phakathi kwazo ekusetshenzisweni okungokoqobo.

I. Ukuzivumelanisa Nezimo Kwezemvelo

Ngaphandle Ikhebula le-Fiber OpticAma-s asetshenziswa kakhulu ezimweni zangaphandle, njenge-overhead, i-duct, kanye nokungcwaba okuqondile. Ngakho-ke, kudingeka abe nokuzivumelanisa nezimo okuhle kwemvelo, akwazi ukumelana nemiphumela yomoya, imvula, ukuchayeka elangeni, izinguquko zokushisa, nezinye izici zemvelo. I-sheath yangaphandle yangaphandle Ikhebula le-Fiber OpticI-s ivame ukwenziwa ngezinto ze-polyethylene noma ze-polyvinyl chloride ezinamandla aphezulu, ezinezakhiwo ezingangeni manzi, ezingangeni umswakama, ezingagqwali, kanye nezingamelani ne-UV ukuqinisekisa ukusebenza okuzinzile isikhathi eside ngaphansi kwezimo zemvelo ezinzima.

Ngokuphambene nalokho, ngaphakathi endlini Ikhebula le-Fiber OpticAma-s asetshenziswa kakhulu ezindaweni zangaphakathi, njengezikhungo zedatha, izakhiwo zamahhovisi, kanye nezakhiwo zokuhlala. Izindawo zangaphakathi zizinzile; ngakho-ke, igobolondo langaphandle lemicu ye-optical yangaphakathi livame ukwenziwa ngezinto ezingenamusi omningi, ezingenayo i-halogen, ezingashisi ilangabi. Lezi zinto azishisi, azishisi ilangabi, azishisi umusi omningi, futhi azinabo ubuthi, okuqinisekisa ukuthi akukho magesi noma intuthu eyingozi ekhiqizwayo uma kwenzeka umlilo, ngaleyo ndlela kuvikela ukuphepha kwabasebenzi.

II. Izici Zokubona

Imicu ye-optical yangaphandle neyangaphakathi nayo iyahluka ngezici zayo zokukhanya. Imicu ye-optical yangaphandle ngokuvamile idinga i-attenuation coefficient ephansi kanye ne-bandwidth ephezulu ukuze ihlangabezane nezidingo zokudlulisa ibanga elide. I-attenuation coefficient ibhekisela ezingeni lokulahleka kwesignali ye-optical ngesikhathi sokudlulisa; i-attenuation coefficient ephansi ivumela amabanga amade okudlulisa. I-bandwidth ibhekisela enanini lolwazi i-fiber engaludlulisela; i-bandwidth ephezulu ivumela ukudluliselwa kwedatha eyengeziwe.

Imicu ye-optical yangaphakathi inezidingo eziphansi kakhulu zokunciphisa i-coefficient kanye ne-bandwidth ngoba amabanga okudlulisa ngaphakathi mafushane, okuholela ekulahlekelweni kwesignali okuncane. Imicu ye-optical yangaphakathi ibeka phambili ukuguquguquka kanye nokulula kokufakwa kwamakhebula ezindaweni ezivalekile.

III. Izindlela Zokuxhumana

Izindlela zokuxhumanisa imicu ye-optical yangaphandle neyangaphakathi nazo ziyahlukahluka. Imicu ye-optical yangaphandle ivame ukusebenzisa i-fusion splicing, indlela enikeza ikhwalithi ephezulu yokuxhumanisa kanye nokuqina, okuqinisekisa ukulahleka okuncane kwesiginali ye-optical ngesikhathi sokudlulisa. I-fusion splicing idinga imishini namasu akhethekile futhi ngokuvamile yenziwa ngabasebenzi abaqeqeshiwe.

Ngaphakathi Ikhebula le-Fiber OpticAma-s avame ukuxhunywa kusetshenziswa izixhumi ezisheshayo noma ama-splices abandayo. Izixhumi ezisheshayo ziyindlela engahlukanisi i-fusion exhumanisa imicu ngomshini, enikeza isivinini, ukulula, kanye nokusebenza kalula. I-cold splicing isebenzisa uketshezi oluhambisanayo ukuxhuma imicu; kulula ukuyisebenzisa, kodwa ikhwalithi yokuxhumana kanye nokuzinza kuphansi kakhulu.

IV. Umehluko Wezindleko

Ngaphandle Ikhebula le-Fiber Opticzidinga ukuzivumelanisa nezimo okuphezulu kwemvelo kanye nezakhiwo zokukhanya, okuholela ezindleleni zokukhiqiza eziphakeme kakhulu. Ngaphezu kwalokho, ukufakwa nokugcinwa kwezindawo zangaphandle Ikhebula le-Fiber Opticzidinga imishini namasu akhethekile, okwandisa izindleko.

Ngaphakathi Ikhebula le-Fiber OpticAma-s anezindleko zokukhiqiza eziphansi kakhulu futhi kulula ukuwafaka nokunakekela, ngaleyo ndlela anikeza inzuzo yezindleko.
