Intambo ye-coaxial yikhebula elinamakhondatha amabili agxilile futhi ikhondukta nesihlangu zabelana nge-eksisi efanayo.
Uhlobo oluvame kakhulu lweikhebula coaxialiqukethe i-conductor yethusi ehlukaniswe yi-insulating material.Ngaphandle kwesendlalelo sangaphakathi se-insulation kunomunye umqhubi we-loop kanye ne-insulator yayo, bese ikhebula lonke limbozwa nge-sheath ye-PVC noma ye-Teflon.
I-Baseband okwamanje iyikhebula elivame ukusetshenziswa elinesihlangu esenziwe ngethusi elisesimweni semeshi enesici esingama-50 (isb. RG-8, RG-58, njll.).
Izintambo ze-Wideband coaxial zivame ukusetshenziswa nezihlangu ezivame ukugxivizwa nge-aluminium futhi zinesici esivimbelayo esingu-75 (isb. RG-59, njll.).
Izintambo zamakhoaxialzingahlukaniswa zibe: izintambo ezimahhadla ze-coaxial kanye nezintambo ezinhle ze-coaxial ngokosayizi wazo wobubanzi.
Ikhebula elimahhadla lifanele amanethiwekhi amakhulu endawo, linebanga elide elijwayelekile nokuthembeka okuphezulu, futhi lingalungiswa ngokuguquguqukayo ngokwesidingo sendawo yokufinyelela kukhompyutha ngoba ukufakwa akudingi ukusika ikhebula, kodwa kufanele kufakwe inethiwekhi yekhebula eqinile. ikhebula le-transceiver, ukufakwa kunzima, ngakho-ke izindleko zizonke ziphezulu.
Ngokuphambene nalokho, ukufakwa kwekhebula elincanyana kulula futhi kungabizi kakhulu, kodwa ngenxa yokuthi inqubo yokufaka kufanele isike ikhebula, zombili iziphetho kufanele zifakwe nezixhumi zenethiwekhi eziyisisekelo (BNC), bese zixhunywa kuzo zombili iziphetho ze-T-connector, ngakho-ke uma kunezixhumi eziningi, kulula ukukhiqiza izinkinga ezimbi ezingase zibe khona, okungenye yokwehluleka okuvamile kwe-Ethernet ekusebenzeni.
Zombili izintambo eziwugqinsi nezincane ziyizinto zebhasi, okungukuthi, imishini eminingi ekhebulani elilodwa.Le topology ifanele izindawo zomshini ominyene, kodwa uma othintana naye oyedwa ehluleka, ukwehluleka kuzothinta yonke imishini kuyo yonke ikhebula ochungechungeni.
Ukuxilongwa nokulungisa iphutha kuyinkinga, ngakho-ke, kancane kancane kuzothathelwa indawo ipheya elisontekile elingavikelekile noma intambo ye-fiber optic.
Izintambo zamakhoaxialbabe nenzuzo yokusekela ukuxhumana komkhawulokudonsa ophezulu emigqeni emide kakhulu, engaphindaphindi, kuyilapho ukonakala kwabo kusobala.
Okokuqala, ubukhulu bobubanzi bekhebula elincane, eliwugqinsi elingamayintshi angu-3/8, ukuze kuthathe isikhala esiningi epayipini lekhebula.
okwesibili ukungakwazi ukumelana nama-tangles, ukucindezeleka nokugoba okunzima, konke okungalimaza isakhiwo sekhebula futhi kuvimbele ukudluliswa kwezimpawu.
Okokugcina izindleko eziphezulu, futhi zonke lezi zingqinamba ziyilokho kanye ipheya elisontekile elingakwazi ukukunqoba, ngakho-ke lithathelwe indawo ngokuyisisekelo ukucaciswa kwesendlalelo somzimba se-Ethernet esisontekile endaweni yamanje ye-LAN.
