Izinto eziningi zensimbi zingasetshenziswa njengezikhondatha zikagesi, zigcwalise indima yokudlulisa amandla nedatha yokusayina ezintanjeni zekhebula, kodwa okuvame ukusetshenziswa kakhulu ithusi. Ikhethwa ezinhlelweni eziningi ngoba iyathandeka kakhulu, inokuhamba kukagesi okuphezulu, ukuguquguquka okuphezulu, amandla aqine kakhulu futhi ayibizi kakhulu, okuyenza ibe yinketho ekhethwayo ezinhlelweni eziningi.
I-Aluminium iphinde ibe yi-conductor impahla yayo eyinhloko ukuthi iminyene kakhulu kunethusi. Kodwa-ke, ukungahambi kahle kwayo kukagesi kusho ukuthi i-cross-section enkulu iyadingeka ukuthwala inani elifanayo lamanje. Ngaphezu kwalokho, izintambo ze-aluminium azigobi ngokwanele, okuholela ekwandeni kwamathuba okuphuka, ngakho-ke akufanelekile ukusetshenziswa kuzinhlelo zokusebenza zeselula. Ngenxa yalesi sizathu, i-aluminiyamu isetshenziswa kakhulu ezintanjeni zokudlulisa amandla kanye nezintambo ze-medium-voltage ngenxa yezidingo zesisindo zezinhlelo ezinjalo.
Phakathi kwezinsimbi, izinto ezingcono kakhulu zokuqhuba isiliva , kodwa zibiza izikhathi eziningi kunethusi. Ngenxa yalokho, isiliva sivame ukusetshenziswa kuphela ezinhlelweni ezikhethekile ezidinga ukusebenza okuphakeme nokusebenza kahle, njengemishini yomsindo ephezulu. Omunye umqhubi ozikhethela wezintambo zomsindo yi-silver-plated copper wire, ehlinzeka nge-conductivity ephezulu kanye nokumelana nokugqwala. Igolide alifaneleki njengomqhubi ngenxa yentengo yalo ephezulu kanye nokungahambi kahle kahle uma kuqhathaniswa nesiliva nethusi.
Kukhona into eyodwa engasebenzisi kakhulu ugesi kunethusi noma i-aluminium, futhi uma uthi nhlá ibonakala ingafaneleki njenge-conductor. Kodwa-ke, ibonakala ngobulukhuni bayo obukhulu kanye nezakhiwo eziqinile - insimbi. Ngenxa yalokho, insimbi isetshenziswa kabanzi ekusetshenzisweni kwezempi kanye ne-aerospace, ngokuvamile ihlanganiswa nezinye izinto ezifana nama-alloys e-aluminium.
Ngokungeziwe kulawa ma-conductor ensimbi, kunemicu yokubona noma ama-waveguides okukhanya. Lezi zifaneleka kahle ekudlulisweni kwesivinini esikhulu samasignali optical. Zihlanganisa ingilazi ye-quartz noma i-plastic fiber core. Lesi sakamuva sivumelana nezimo futhi ngenxa yalokho kulula ukugoba. I-fiber core ihlala ngaphakathi kwe-cladding evikelayo, ebizwa ngokuthi i-cladding. Ukukhanya kubonakala phakathi kwe-optical core kanye ne-cladding futhi ngaleyo ndlela kudluliselwa ngesivinini esikhulu nge-waveguide. I-Optical waveguides isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezifana nezokuxhumana, imithi kanye ne-aerospace. Nokho, abakwazi ukudlulisa imisinga kagesi.
Ukukhethwa kwempahla ye-conductor ephezulu kuncike ekusetshenzisweni okuqondile kanye nezimo ezikhona. Ukuze ukwazi ukucabangela ngokucophelela izinzuzo nezingozi zento ngayinye, kubalulekile ukuqonda izakhiwo zezinto ezibonakalayo. Yiqiniso, ezinye izici zekhebula, njengendlela yokumisa, indawo enqamula ingxenye, i-insulation kanye ne-sheath material nayo idlala indima ebalulekile. Ngalesi sizathu, ungaphinda ufune izeluleko zochwepheshe bezintambo ekukhetheni izintambo nezintambo ukuze uqinisekise ukuthi zonke izidingo zokusetshenziswa kwansuku zonke ziyahlangatshezwa.
