Intambo ye-coaxial yintambo enee-concentric conductors ezimbini kunye nomqhubi kunye nekhaka babelana nge-axis efanayo.
Olona hlobo luqhelekileyo lweintambo ye-coaxialiqulethe i-conductor yobhedu ehlukaniswe yi-insulating material.Ngaphandle kwendawo yangaphakathi yokugquma kukho enye i-conductor ene-loop kunye ne-insulator yayo, kwaye ke yonke intambo igqunywe nge-sheath ye-PVC okanye i-Teflon.
I-Baseband okwangoku yintambo esetyenziswa ngokuqhelekileyo enekhaka elenziwe ngobhedu ngendlela ye-mesh ene-impedance ye-50 (umz. RG-8, RG-58, njl.).
Iintambo ze-Wideband coaxial ziqhele ukusetyenziswa kunye namakhaka adla ngokugximfizwa nge-aluminiyam kwaye anophawu oluthintelayo lwe-75 (umz. RG-59, njl.).
Iintambo ze-coaxialzinokwahlulwa zibe: iintambo ezirhabaxa zecoaxial kunye neentambo ezicolekileyo zecoaxial ngokobungakanani bazo bobukhulu.
Intambo erhabaxa ilungele uthungelwano olukhulu lwasekhaya, inomgama omde osemgangathweni kunye nokuthembeka okuphezulu, kwaye inokulungelelaniswa ngokuguquguqukayo ngokwesidingo sendawo yokufikelela kwikhompyuter kuba ukufakela akudingi kusika intambo, kodwa kufuneka kufakwe inethiwekhi yentambo erhabaxa. intambo ye-transceiver, ukufakela kunzima, ngoko ke ixabiso lilonke liphezulu.
Ngokuchasene noko, ukufakwa kwentambo ebhityileyo kulula kwaye kungabizi kakhulu, kodwa ngenxa yokuba inkqubo yofakelo kufuneka inqumle intambo, zombini iziphelo kufuneka zifakwe kunye nezihlanganisi ezisisiseko zenethiwekhi (BNC), kwaye emva koko ziqhagamshelwe kuzo zombini iziphelo ze-T-connector, ke xa kukho izihlanganisi ezininzi, kulula ukuvelisa iingxaki ezimbi ezinokubakho, enye yezona ntsilelo zixhaphakileyo ze-Ethernet ekusebenzeni.
Zombini iintambo ezishinyeneyo nezibhityileyo zii-topology zebhasi, oko kukuthi, oomatshini abaninzi kwintambo enye.Le topology ifanelekile kwiindawo ezixineneyo zomatshini, kodwa xa umfowunelwa omnye engaphumeleli, ukusilela kuya kuchaphazela bonke oomatshini kwintambo yonke kuthotho.
Ukuxilongwa kwempazamo kunye nokulungiswa kuyingxaki, ke ngoko, kuya kutshintshwa ngokuthe ngcembe iperi ejijekileyo engakhuselekanga okanye intambo yefiber optic.
Iintambo ze-coaxialbabe nenzuzo yokuxhasa unxibelelwano lwe-bandwidth ephezulu ngaphezulu kwemigca emide, ephindaphindayo, ngelixa izinto ezingalunganga zibonakala.
Okokuqala, ubungakanani bentambo enkulu, ebhityileyo ububanzi kwi-3/8 intshi ubukhulu, ukuthatha indawo enkulu kumbhobho wentambo.
okwesibini ukungakwazi ukumelana nama-tangles, uxinzelelo kunye nokugoba okunzima, konke oko kungonakalisa isakhiwo sekhebula kunye nokuthintela ukuhanjiswa kweempawu.
Elokugqibela lixabiso eliphezulu, kwaye zonke ezi zithintelo yile nto kanye isibini esijijekileyo esinokuyoyisa, ngoko ke iye yathatyathelwa indawo yi-Ethernet ejijekileyo esekwe kwi-Ethernet yokubekwa kweempawu kwimeko yangoku ye-LAN.
