Isingeniso：
Izintambo ze-feeder zidlala indima ebaluleke kakhulu ezinhlelweni zokuxhumana zesimanje emhlabeni jikelele. Lezi yizintambo ezikhethekile ezenzelwe ukuthuthukisa ukusebenza kahle kanye nokusebenza kahle kokudluliselwa kwesignali, ikakhulukazi eziteshini zokudlulisela zenethiwekhi yokusakaza. Ingqikithi yokuba nezintambo ze-feeder isemandleni azo okuletha amandla kanye nezibonakaliso phakathi kwezingxenye ezahlukene ngaphakathi kwesistimu ngenxa yomthamo wazo wokuthwala ophezulu kanye nokulahleka okuphansi kwesignali.
Izinhlobo kanye nesakhiwo sezintambo ze-Feeder:
Ngokuvamile, izintambo ze-feeder zihlukaniswe ngezinhlobo ezimbili eziyinhloko: i-coaxial kanye ne-fiber optic. Eyokuqala, i-coaxial, isetshenziswa kabanzi ngaphakathi kwezinhlelo zokusebenza ze-radio frequency (RF) ngenxa yokuhlukaniswa kwayo okuhle kakhulu ekuphazamisekeni kwe-electromagnetic yangaphandle. Le ntambo iqukethe umqhubi wangaphakathi, i-insulator, umqhubi wangaphandle, kanye ne-sheath yangaphandle. Ibhalansi enhle kakhulu phakathi kokusebenza kanye nezindleko ivame ukutholakala ngezintambo ze-coaxial, okwenza zibe ukukhetha okuthandwayo embonini yezokuxhumana.
Ngakolunye uhlangothi, izintambo ze-fiber optic zisebenza njengendlela engcono lapho kudingeka khona ukudluliselwa kwesignali yebanga elide. Lezi zintambo zisebenzisa imicu yezintambo zeglasi ngaphakathi kwebhokisi elivalekile, okuvumela ukudluliselwa kwedatha ngokushesha okukhulu.
Izicelo zezintambo ze-Feeder:
Izintambo ze-feeder zivame ukusetshenziswa emikhakheni eyahlukene, okuhlanganisa ukusakaza, ukuxhumana ngocingo, ubuchwepheshe bolwazi, ezempi, nokuningi. Ukusetshenziswa kwazo ekuthuthweni kwezimpawu kusuka emthonjeni ophakathi kuya emgqeni wokusabalalisa noma kumadivayisi amaningi kuyiphuzu elibalulekile lokuthengisa. Lezi zintambo zisetshenziswa kakhulu ekusethweni kwamanethiwekhi eselula, lapho izimpawu kufanele zidluliselwe kusuka esiteshini esiyisisekelo ziye ohlelweni lwe-antenna.
Izintambo zokuhambisa nazo zibalulekile ekusebenzeni kwamanethiwekhi ethelevishini yekhebula. Zinesibopho sokuthutha izimpawu zethelevishini zisuka emthonjeni oyinhloko wokudlulisa ziye ku-antenna yomphakathi, ziqinisekisa ikhwalithi yesithombe ephezulu lapho zimukelwa.
Izinzuzo zezintambo ze-Feeder:
Okuphawulekayo ukuthi izici ezivelele zezintambo eziphakelayo amandla azo okuthwala aphezulu, ukulahleka kwesignali okuphansi, kanye nokumelana nokuphazamiseka kwe-electromagnetic. Zenzelwe ngokuqinile ukusebenza kahle ngaphansi kwezimo ezinzima. Izingxenye ezibalulekile zezinhlelo eziningi zokusakaza kanye nezokuxhumana, lezi zintambo zisiza ekudlulisweni kwesignali okunembile nokusheshayo kumabanga ahlukahlukene.
Isiphetho：
Ekuphetheni, izintambo ze-feeder ziyinsika yezokuxhumana zanamuhla, izinhlelo zokusakaza, kanye namanethiwekhi angenantambo, okuqhuba umhlaba oncike kakhulu ekuxhumaneni okusheshayo, okusebenzayo, nokuthembekile. Amandla azo okunciphisa ukulahleka kwesignali, ukumelana kwazo nokuphazamiseka, kanye nomthamo wazo wokuthwala wonke kuzenza zibe yingxenye ebalulekile emikhakheni ehlukahlukene yomnotho. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, nesidingo sokuthuthukiswa okuhambisanayo kwezintambo ze-feeder, okugcizelela ukubaluleka kwazo okuyisisekelo ezweni lethu elixhumene.
