I. Kungani izintambo ze-fiber optic ziphila isikhathi eside kangaka?
1️⃣ I-transmission medium "ayigugi"

I-fiber optic core yenziwe ngengilazi ye-quartz.

Ayikhiqizi i-oxidize, ayikhiqizi ugesi, futhi ayithintwa ukuphazamiseka kwe-electromagnetic.

Uma nje ingalimalanga ngokomzimba, ukusebenza kwayo akubi kakhulu.

1. Isivikelo Sangaphandle: Izintambo ze-fiber optic zangaphakathi ngokuvamile zisebenzisa i-polyvinyl chloride (PVC) noma i-PVC evimbela ilangabi. Indawo yangaphandle kufanele ibe bushelelezi, ikhazimle, iguquguquke, futhi kube lula ukuyisusa. Izintambo ze-fiber optic zekhwalithi embi zinendawo yangaphandle erhabaxa futhi zivame ukunamathela ku-buffer yangaphakathi eqinile kanye nemicu ye-aramid.

Izintambo ze-fiber optic (noma nje "izintambo ze-optical") ziyizintambo zokuxhumana ezisebenzisa imicu ye-optical (imicu yengilazi noma yepulasitiki) njengendlela yokudlulisa eyinhloko. Zifinyelela ukudluliselwa kwedatha, izwi, nezithombe ngesivinini esikhulu ngokusebenzisa isimiso sokubonakaliswa kwangaphakathi kwezibonakaliso zokukhanya. Ziqukethe imicu ye-optical eminingi noma eyodwa, ungqimba olungaphandle oluvikelayo, ukuqinisa (njenge-Kevlar fiber), kanye ne-sheath. Ziyakwazi ukudluliselwa kwesignali okuzinzile emabangeni amade kanye nama-bandwidth aphezulu, ziyingxenye eyinhloko yengqalasizinda yolwazi yesimanje.

Umsebenzi Oyinhloko: Ukudlulisa Ulwazi Njengokukhanya
Ngokuyisisekelo, ikhebula le-fiber optic liwumucu wengilazi noma wepulasitiki omncane ofana noboya odlulisela ulwazi kusuka endaweni eyodwa kuya kwenye kusetshenziswa ukukhanya.

Izintambo ze-fiber optic sezibe umgogodla wezinhlelo zokuxhumana zanamuhla. Zidlulisela idatha ngesimo sezimpawu ezibonakalayo ngemicu yengilazi encane noma yepulasitiki. Enye yezinzuzo ezibaluleke kakhulu zezintambo ze-fiber optic yikhono lazo lokudlulisa idatha ebangeni elide ngaphandle kokulahlekelwa okukhulu kwesignali. Lesi sihloko sizohlola izici ezithinta ibanga elingahanjwa yisignali ezintanjeni ze-fiber optic.

I. Ukuzivumelanisa Nezimo Kwezemvelo

Izintambo ze-fiber optic zangaphandle zisetshenziswa kakhulu ezimweni zangaphandle, njenge-overhead, i-duct, kanye nokungcwaba okuqondile. Ngakho-ke, zidinga ukuba nezimo ezinhle zemvelo, zikwazi ukumelana nemiphumela yomoya, imvula, ukuchayeka elangeni, izinguquko zokushisa, nezinye izinto zemvelo. I-sheath yangaphandle yezintambo ze-fiber optic zangaphandle 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.

1. Hlola izimpawu kanye nokuphrinta

Igobolondo langaphandle lekhebula livame ukuba nenombolo yemodeli kanye nemininingwane ephrintiwe kulo. Bheka izinhlamvu ezilandelayo ezibalulekile:

I-Fiber Optic: I-Fiber, i-Optical, i-Fiber Optic, i-OFN (i-Optical Fiber Non-conductive), i-OFNP (i-Flame Retardant), i-GYFTY (ikhebula le-Optical langaphandle), njll.

Amakhodi Emodeli: Lawo aqala ngo-GY, GJ, GJF, ADSS, njll., ngokuvamile amakhebula e-optical. Lawo aqala ngo-CAT5, CAT5e, CAT6, CAT6A, njll., amakhebula ethusi (amakhebula enethiwekhi).

1. Iyini ikhebula lokuphepha?

Ikhebula lokuphepha alilona uhlobo oluthile lwekhebula; lingumqondo osebenzayo. Ngokubanzi libhekisela ezintanjeni eziqinisekisa ukuzinza nokuthembeka kokudluliswa kwamandla, ukulawulwa kwesignali, kanye nokuxhumana ngaphansi kwezimo ezimbi kakhulu noma eziyingozi, futhi zivimbela ngempumelelo izingozi ezifana nomlilo, ukushaqeka kukagesi, umonakalo wemishini, noma ukwehluleka kohlelo okubangelwa izinkinga zekhebula.

Inani labo eliyinhloko lisekuvikeleni "ukuphepha kokuphila kanye nempahla."

Yiziphi izinhlobo ezintathu zezintambo ze-fiber optic?

1. I-Fiber yemodi eyodwa
I-fibre yemodi eyodwa uhlobo lwe-fibre oludlulisela imodi eyodwa kuphela (indlela) yokukhanya. Ine-core encane kakhulu (ngokuvamile ububanzi obuyi-8-10 microns).

Indlela esebenza ngayo: Ngenxa yokuthi umongo mncane kakhulu, ukukhanya kusakazeka endleleni eyodwa eqondile, ngaphandle kokukhanya noma ukuhlakazeka. Kufana nomsebe we-laser pointer—kugxile kakhulu.
