Uma kuziwa ekufakweni kwasemoyeni, izinketho ezimbili ezidumile zezintambo ze-fiber optic ikhebula le-ADSS (All-Dielectric Self-Supporting) kanye nentambo ye-OPGW (Optical Ground Wire).Zombili izintambo zinezinzuzo nezinkinga zazo, ngakho-ke kubalulekile ukucabangela izidingo ezithile zokufakwa ngaphambi kokunquma ukuthi iyiphi engcono.
Ikhebula le-ADSS wuhlobo lwekhebula le-fiber optic elakhelwe ukuthi likwazi ukuzisekela ngaphandle kwesidingo sentambo yensimbi yesithunywa.Lokhu kuyenza ibe inketho engasindi futhi elula ukuyifaka yokufakwa emoyeni.Ikhebula le-ADSS nalo alikwazi ukumelana nokugqwala nokulimala okuvela ezintweni ezizungezile, okuyenza ibe ukukhetha okuqinile ukufakwa ezindaweni ezinesimo sezulu esibi.
Ngakolunye uhlangothi, ikhebula le-OPGW yikhebula le-fiber optic elifakwe emibhoshongweni yokudlulisela amandla kagesi aphezulu.Iqukethe imicu ye-optical evalwe ungqimba lwe-aluminium nensimbi, ehlinzeka kokubili ukuguquguquka kagesi nokubonakalayo.Ikhebuli ye-OPGW yakhelwe ukumelana nezimo zezulu eziyingozi futhi imelana nokulimala okuvela ezintweni zemvelo.
Mayelana nokusebenza, zombili izintambo ze-ADSS ne-OPGW ziyakwazi ukudlulisa idatha ngesivinini esiphezulu ebangeni elide.Nokho, ikhebuli ye-OPGW ngokuvamile inomthamo womkhawulokudonsa ophezulu kunekhebula le-ADSS, okuyenza ibe ukukhetha okungcono kokufaka okudinga ukudluliswa kwedatha okunesivinini esikhulu nokuthembekile.
Esinye isici okufanele sicatshangelwe yizindleko zokufakwa.Ikhebula le-ADSS ngokuvamile libiza kancane ukulifaka kunekhebula le-OPGW, njengoba lingadingi intambo yensimbi yesithunywa.Nokho, ikhebuli ye-OPGW ingase ibe inketho engabizi kakhulu ngokuhamba kwesikhathi, njengoba idinga ukulungiswa okuncane futhi inokuphila okude kunekhebula le-ADSS.
Sengiphetha, zombili izintambo ze-ADSS ne-OPGW ziyizinketho ezifanele zokufakwa emoyeni.Ukukhetha phakathi kwalokhu kokubili kuncike ezidingweni ezithile zokufakwa, okuhlanganisa nomkhawulokudonsa odingekayo, izici zemvelo, nokucatshangelwa kwezindleko.Ekugcineni, kubalulekile ukubonisana nochwepheshe ukuze unqume ukuthi iyiphi ikhebula elungele ukufakwa.
