I-OPGW (Optical Ground Wire) iwuhlobo lwekhebula elisetshenziswa embonini yezokuxhumana ukudlulisa idatha ngobuchwepheshe be-fiber optic, kuyilapho ihlinzeka nokudluliswa kwamandla kagesi ezintanjeni zamandla kagesi aphezulu. Izintambo ze-OPGW ziklanywe ngeshubhu elimaphakathi noma ingqikithi, okubekwe eduze kwayo isendlalelo esisodwa noma eziningi zensimbi noma izintambo ze-aluminium, kanye nongqimba olungaphandle lwemicu yokubona. Ukwakhiwa kwezintambo ze-OPGW kuyahlukahluka kuye ngohlelo lokusebenza kanye nezidingo ezithile zesistimu yezintambo zikagesi.
Kunezinhlobo ezintathu eziyisisekelo zezakhiwo zekhebula le-OPGW:
I-Central Tube: Lolu hlobo lwekhebula luqukethe ishubhu eliphakathi nendawo, elizungeze izintambo zensimbi ezibekiwe noma izintambo ze-aluminium alloy. Khona-ke ama-optical fibers abekwa epayipini. Lo mklamo uvumela ukuguquguquka okukhulu futhi unikeze isikhala esengeziwe semicu ye-optical.
I-Layer Stranding: Lolu hlobo lwekhebula lunezingqimba ezimbalwa zensimbi noma izintambo ze-aluminium eziboshelwe ndawonye. Imicu ye-optical ibekwe phakathi kwama-interstices phakathi kwezintambo. Lo mklamo unikeza amandla engeziwe futhi ulungele kakhulu izinhlelo zokusebenza ezicindezelayo.
I-Unitube: Lolu hlobo lwekhebula luneshubhu elilodwa lapho kokubili izintambo zensimbi noma ze-aluminium kanye nemicu yokubona kubekwa khona. Lo mklamo uhlinzeka ngekhebula elihlangene okulula ukulifaka.
Izintambo ze-OPGW nazo zingahlukaniswa ngokusekelwe ekubalweni kwefayibha, esukela ku-12 kuya ku-288 imicu. Ukukhethwa kwesibalo sefayibha kuncike ekusetshenzisweni okukhethekile kanye nezidingo zamandla zesistimu yezintambo zamandla.
