Intshayelelo:
Iintambo ze-feeder zidlala indima ebalulekileyo kwiinkqubo zonxibelelwano zanamhlanje kwihlabathi liphela. Ezi ziintambo ezikhethekileyo ezenzelwe ukuphucula ukusebenza kakuhle nokusebenza kakuhle kokudluliselwa kwesignali, ingakumbi kwizikhululo zokudluliselana zenethiwekhi yosasazo. Umongo wokuba neentambo ze-feeder ukwikhono lazo lokuhambisa amandla kunye nemiqondiso phakathi kwezinto ezahlukeneyo kwinkqubo ngenxa yomthamo wazo ophezulu wokuthwala kunye nokulahleka okuphantsi kwesignali.
Iintlobo kunye nolwakhiwo lweeCables zeFeeder:
Ngokubanzi, iintambo ze-feeder zahlulwe zibe ziintlobo ezimbini eziphambili: i-coaxial kunye ne-fiber optic. Eyokuqala, i-coaxial, isetyenziswa kakhulu kwizicelo zerediyo (RF) ngenxa yokwahlulwa kwayo okuphuculweyo kwi-external electromagnetic interference. Le ntambo iquka i-inner conductor, i-insulator, i-outer conductor, kunye ne-outer sheath. Ibhalansi entle phakathi kokusebenza kunye neendleko idla ngokufumaneka ngeentambo ze-coaxial, nto leyo eyenza ukuba zibe lukhetho oludumileyo kushishino lonxibelelwano.
Kwelinye icala, iintambo ze-fiber optic zisebenza njengendlela engcono apho kufuneka khona ukudluliselwa kwesignali kumgama omde. Ezi ntambo zisebenzisa imicu yeglasi ngaphakathi kwibhokisi egqunyiweyo, evumela ukudluliselwa kwedatha ngokukhawuleza kombane.
Usetyenziso lweeCables zeFeeder:
Iintambo ze-feeder zisetyenziswa kakhulu kumacandelo ahlukeneyo, kuquka ukusasaza, unxibelelwano, ubuchwepheshe bolwazi, umkhosi, nokunye. Ukusetyenziswa kwazo ekuhambiseni imiqondiso ukusuka kumthombo ophakathi ukuya kumgca wokusasaza okanye kwizixhobo ezininzi yindawo ebalulekileyo yokuthengisa. Ezi ntambo zisetyenziswa kakhulu ekusetweni kwenethiwekhi zeselula, apho imiqondiso kufuneka idluliselwe ukusuka kwisikhululo sesiseko ukuya kwinkqubo ye-antenna.
Iintambo ze-feeder nazo zibalulekile ekusebenzeni kweenethiwekhi zethelevishini zekhebula. Zinoxanduva lokuthutha imiqondiso yethelevishini ukusuka kumthombo ophambili wothumelo ukuya kwi-antenna yoluntu, ukuqinisekisa umgangatho ofanelekileyo womfanekiso xa ufunyanwa.
Iingenelo zeeCables zeFeeder:
Okuphawulekayo kukuba, iimpawu eziphambili zeentambo ze-feeder kukuba zithwala amandla aphezulu, zilahlekelwa yisignali ephantsi, kwaye azinakumelana nokuphazamiseka kwe-electromagnetic. Zenzelwe ukuba zisebenze ngokufanelekileyo phantsi kweemeko ezinzima. Ezi ntambo zibalulekileyo kwiinkqubo ezininzi zokusasaza kunye nonxibelelwano, zinceda ekuhanjisweni ngokuchanekileyo nangokukhawuleza kwemiqondiso kumgama owahlukeneyo.
Isiphelo:
Ukuqukumbela, iintambo ze-feeder zisisiseko sonxibelelwano lwanamhlanje, iinkqubo zokusasaza, kunye neenethiwekhi ezingenazingcingo, ziqhuba ihlabathi elixhomekeke ngakumbi kunxibelelwano olukhawulezayo, olusebenzayo, noluthembekileyo. Amandla azo okunciphisa ukulahleka kwesignali, ukumelana kwazo nokuphazamiseka, kunye nomthamo wazo wokuthwala umbane zizenza zibe yinxalenye ebalulekileyo kumacandelo ahlukeneyo oqoqosho. Njengoko ubuchwepheshe buqhubeka buhambela phambili, kukwakho nesidingo sokuphuculwa okufanayo kwiintambo ze-feeder, nto leyo egxininisa ukubaluleka kwazo kwihlabathi lethu elidibeneyo.
