I-Fiber Optic Cable (FOC) iyingxenye ebalulekile yenethiwekhi yezokuxhumana yesimanje, futhi inesikhundla esibalulekile emkhakheni wokudluliswa kwedatha enezici zayo zejubane eliphezulu, umkhawulokudonsa ophezulu kanye nekhono eliqinile lokulwa nokuphazamiseka. Lesi sihloko sizokwethula ukwakheka kwentambo ye-fiber optic ngokuningiliziwe ukuze abafundi babe nokuqonda okujulile ngakho.
1. Ukwakheka okuyisisekelo kwentambo ye-fibre-optic
Intambo ye-fiber optic ngokuyinhloko yakhiwe izingxenye ezintathu: i-fiber optic core, i-cladding kanye ne-sheath.
I-Fiber optic core: Lona umnyombo wentambo ye-fiber optic futhi unesibopho sokudlulisa amasignali okukhanya. Ama-fiber optic cores ngokuvamile enziwa ngengilazi emsulwa kakhulu noma ngepulasitiki, enobubanzi obungama-microns ambalwa kuphela. Ukuklanywa kwe-core kuqinisekisa ukuthi isignali ye-optical ihamba ngayo ngokuphumelelayo futhi ngokulahlekelwa okuphansi kakhulu.
Ukugqoka: Okuvalwe eduze komgogodla wefayibha i-cladding, inkomba yayo ye-refractive iphansi kancane kunaleyo ye-core, futhi eklanyelwe ukuvumela isignali ye-optical ukuthi idluliselwe ku-core ngendlela ekhanyayo ngokuphelele, ngaleyo ndlela yehlise ukulahlekelwa kwesignali. I-cladding yenziwe ngengilazi noma ngepulasitiki futhi ivikela ngokomzimba umongo.
Ijakhethi: Ijazi elingaphandle lenziwe ngezinto eziqinile ezifana ne-polyethylene (PE) noma i-polyvinyl chloride (PVC), umsebenzi wayo oyinhloko ukuvikela i-fiber optic core kanye nokuvala emonakalweni wemvelo njengokugwaza, umswakama nokugqwala kwamakhemikhali.
2. Izinhlobo zezintambo ze-fibre-optic
Ngokuvumelana nokuhlelwa nokuvikelwa kwama-optical fibers, izintambo ze-fiber optic zingahlukaniswa zibe izinhlobo ezilandelayo:
Intambo ye-fiber optic ene-laminated stranded: lesi sakhiwo sifana nezintambo zendabuko, lapho imicu eminingi ye-optical iboshelwe endaweni emaphakathi yokuqinisa, idala ukubukeka okufana nalokho kwezintambo zakudala. Izintambo ze-fiber optic ezinemicu ene-laminated zinamandla aqinile aqinile kanye nezakhiwo ezinhle zokugoba, futhi anobubanzi obuncane, okwenza kube lula ukuzihambisa nokuzinakekela.
Ikhebula lesikelethoni: le khebula isebenzisa uhlaka lwepulasitiki njengesakhiwo sokusekela se-fiber optical, i-fiber optical igxiliwe emiseleni yohlaka lwamathambo, enezici ezinhle zokuvikela nokuzinza kwesakhiwo.
Ikhebuli yeshubhu yenqwaba emaphakathi: i-fiber optical ibekwe phakathi nendawo ye-optical cable tube, ezungezwe umgogodla wokuqinisa kanye nokuvikelwa kwejacket, lesi sakhiwo sihambisana nokuvikelwa kwezintambo ezibonakalayo ezivela emathonyeni angaphandle.
Intambo yeribhoni: ama-optical fibers ahlelwe ngendlela yamaribhoni anezikhala phakathi kweribhoni yefiber ngayinye, lo mklamo usiza ukuthuthukisa amandla aqinile kanye nokumelana nokucindezela kwe-lateral kwekhebula.
3. Izingxenye ezengeziwe zezintambo ze-fibre-optic
Ngokungeziwe kuma-fiber optical ayisisekelo, i-cladding ne-sheath, izintambo ze-fiber optic zingaqukatha lezi zingxenye ezilandelayo:
Umgogodla wokuqinisa: Itholakala maphakathi nentambo ye-fiber optic, inikeza amandla emishini engeziwe ukuze imelane namandla aqinile nezingcindezi.
Isendlalelo sebhafa: Itholakala phakathi kwefayibha nomgodla, iphinde ivikele i-fiber emthelela nasekuhuzukeni.
Isendlalelo sezikhali: Ezinye izintambo ze-fiber optic nazo zinesendlalelo esengeziwe se-armouring, njengensimbi ye-armorouring yensimbi, ukuze kuhlinzekwe ukuvikeleka okwengeziwe kwezindawo ezinokhahlo noma lapho kudingeka khona ukuvikeleka kwemishini okwengeziwe.
4. Izinqubo zokukhiqiza zezintambo ze-fibre-optic
Ukwenziwa kweizintambo ze-fiber optickuhilela inqubo yokunemba okuphezulu, okuhlanganisa izinyathelo ezinjengokudweba kwe-fiber optics, ukumbozwa kokugqoka, ukubopha, ukwakheka kwekhebula kanye nokukhishwa kwe-sheath. Isinyathelo ngasinye sidinga ukulawulwa ngokuqinile ukuze kuqinisekiswe ukusebenza kanye nekhwalithi yentambo ye-fiber optic.
Kafushane, idizayini yesakhiwo yezintambo ze-fiber optical icabangela kokubili ukudluliselwa okuphumelelayo kwamasignali okubona kanye nokuvikelwa ngokomzimba kanye nokuvumelana nezimo zemvelo. Ngokuqhubeka okuqhubekayo kobuchwepheshe, ukwakheka nezinto zokwakha zezintambo ze-fiber optic ziyathuthukiswa ukuze zihlangabezane nesidingo esikhulayo sokuxhumana.
