Ukufakwa emoyeni kubalulekile ekudluliseni amandla namasignali okuxhumana ebangeni elide. Enye yezingxenye ezibaluleke kakhulu zokufakwa emoyeni yikhebula elisetshenziswayo. Izintambo ezimbili ezivame ukusetshenziswa zokufakwa emoyeni yi-ADSS (All-Dielectric Self-Supporting) kanye ne-OPGW (Optical Ground Wire). Zombili izintambo zinezinzuzo nezinkinga zazo, kodwa yikuphi okunikeza ukusebenza okungcono kokufakwa emoyeni?
Izintambo ze-ADSSzenziwe ngokuphelele ngezinto ze-dielectric, okusho ukuthi azinazo izingxenye zensimbi. Lesi sici sibenza babe lula futhi bavikeleke ekugqwaleni, okuyinzuzo ephawulekayo ezimweni zezulu ezinzima. Amakhebuli e-ADSS nawo kulula ukuwafaka, okuwenza abe yintandokazi ezinkampanini ezisizayo.
Ngakolunye uhlangothi, izintambo ze-OPGW zine-conductor eyinsimbi emaphakathi enemicu yokubona eshumekwe ongqimbeni lwensimbi ne-aluminium. Lo mklamo unikeza amandla aphakeme nokuqina, okuwenza alungele ukufakwa ezindaweni ezinomoya omkhulu noma ezinye izimo zezulu ezimbi kakhulu. Ukwengeza, izintambo ze-OPGW zinikeza indlela enhle kakhulu yombani ongadlula kuyo, okuzenza zibe ukukhetha okudumile ezindaweni ezinombani ophezulu.
Ngakho-ke, iyiphi ikhebula enikeza ukusebenza okungcono kokufakwa emoyeni? Impendulo incike ezintweni ezimbalwa, okuhlanganisa indawo yokufaka, ukusetshenziswa okuhlosiwe kwentambo, kanye nesabelomali.
Ezinkampanini ezisizayo ezifuna ikhebuli engasindi nefakeka kalula, i-ADSS ingaba inketho engcono. Nokho, uma ukufakwa kusendaweni enezimo zezulu ezimbi kakhulu, i-OPGW ingase ibe inketho engcono ngenxa yamandla ayo aphakeme nokuqina.
Sengiphetha, ukukhetha phakathi kwe-ADSS neIzintambo ze-OPGWkuncike ezidingweni ezithile zokufakwa. Ukucatshangelwa ngokucophelela kwezinto ezifana nendawo ezungezile, ukusetshenziswa okuhlosiwe, nesabelomali kungasiza ekwenzeni isinqumo esinolwazi ngokuthi iyiphi ikhebula okufanele isetshenziswe.
