Ngenxa yomkhawulo wobude nokunwetshwa kobude, ukumbozwa kwamathaneli kuhlala kuyinselele kubasebenzisi.Izici zomhubhe zikhawulela izindlela zendlela yokuhlinzeka ngekhava.Imigudu engaphansi komhlaba noma yesitimela ngokuvamile mincane, futhi inohlangothi olungaphezulu oluphansi;kuyilapho imigudu yomgwaqo ivame ukuba ne-headroom enkulu futhi ivulekile.Ngokuvamile, imigudu isetshenziswa kuphela ngezikhathi ezithile;ngakho-ke, isici sohlelo lokusebenza oluvumelana nezimo, isikhathi sokuqalisa esisheshayo, kanye nezindleko eziphansi kwenze ophindayo abe yisinqumo esihle njengesixazululo sokumboza isignali yomhubhe.
Ngenxa yezici zezindawo zomhubhe, kunzima kakhulu ukuthi isignali ekhishiwe yesiteshi esiyisisekelo ihambe yonke indlela emhubheni ngaphandle uma isiteshi esiyisisekelo senzelwe ukumbozwa komhubhe.Ngakho-ke, umhubhe omningi unenkinga yokumbozwa kahle kwamasignali.Ngaphandle kokusebenzisa isiteshi sesisekelo esikhethekile sokumboza umhubhe, i-Fiber Optic Repeater futhi iyisixazululo esifanelekile sokumboza umhubhe, kuyilapho i-High Power Repeater ingasetshenziswa ukuze kuthuthukiswe ukumbozwa kwesignali emhubheni.
