Umugozi wa Coaxial (nyuma yiswe "coax") ni umugozi ugizwe nu byuma bibiri bya coaxial na insulente ya silindrike ikora ibice shingiro (coaxial couple), hanyuma bigahurira hamwe cyangwa byinshi.Byakoreshejwe mu kohereza amakuru n'ibimenyetso bya videwo igihe kirekire.Nibimwe mubitangazamakuru byambere bishyigikira 10BASE2 na 10BASE5 Ethernet, kandi birashobora kugera kuri 10 Mb / s byohereza metero 185 cyangwa metero 500.Ijambo "coaxial" risobanura ko umuyobozi mukuru wa kabili hamwe nigice cyacyo cyo gukingira bifite umurongo umwe cyangwa ingingo nkuru.Intsinga zimwe za coaxial zirashobora kugira ibice byinshi byo gukingira, nkinsinga enye zikingiwe.Umugozi urimo ibice bibiri byo gukingira, kandi buri gice cyo gukingira kigizwe na fayili ya aluminiyumu ipfunyitse hamwe na meshi.Uku gukingira kuranga insinga ya coaxial ituma igira imbaraga zikomeye zo kurwanya anti-electromagnetic kandi ishobora kohereza ibimenyetso byinshyi nyinshi intera ndende.Hariho ubwoko bwinshi bwinsinga za coaxial zishyigikira ibikorwa byinshi byumwuga, nkitumanaho rya satelite, inganda, igisirikare ninyanja.Ubwoko butatu busanzwe bwinsinga zidafite inganda ni RG6, RG11 na RG59, murizo RG6 ikoreshwa cyane mubikorwa bya CCTV na CATV mubidukikije.Umuyoboro wo hagati wa RG11 ubyibushye kuruta RG6, bivuze ko igihombo cyacyo kiri hasi kandi intera yohereza ibimenyetso nayo ni ndende.Nyamara, umugozi muremure wa RG11 uhenze cyane kandi ntiworoshye, ibyo bigatuma bidakwiriye koherezwa mubikorwa byimbere, ariko bikwiranye no gushiraho intera ndende yo hanze cyangwa guhuza umugongo.Ihinduka rya RG59 ni ryiza kuruta irya RG6, ariko igihombo cyayo ni kinini, kandi ni gake gikoreshwa mu zindi porogaramu usibye umurongo mugari muto, amashusho yerekana amashusho make (reba inyuma-kamera mu modoka) ufite intera ngufi kandi ntarengwa Umwanya.Inzitizi y'insinga za coaxial nazo ziratandukanye - mubisanzwe 50, 75, na 93 Ω.Umugozi wa 50 Ω coaxial ufite ubushobozi bwo gutunganya ingufu nyinshi kandi ukoreshwa cyane cyane mumashanyarazi, nkibikoresho bya radio yikinira, amaradiyo ya gisivili (CB) na talkie-talkie.Umugozi wa 75 Ω urashobora gukomeza neza imbaraga zerekana ibimenyetso kandi ukoreshwa cyane cyane muguhuza ubwoko butandukanye bwibikoresho byakira, nka televiziyo ya kabili (CATV), televiziyo isobanura cyane hamwe na mashusho yerekana amashusho.93 cable insinga ya coaxial yakoreshejwe murusobe rwibanze rwa IBM mumyaka ya za 1970 nintangiriro za 1980, hamwe na progaramu nkeya kandi zihenze.Nubwo 75 Ω inzitizi ya kabili ya coaxial ikunze kugaragara mubisabwa byinshi muri iki gihe, twakagombye kumenya ko ibice byose biri muri sisitemu ya kabili ya coaxial bigomba kugira inzitizi imwe kugirango birinde kwigaragaza imbere aho bihurira bishobora gutera gutakaza ibimenyetso no kugabanya ubwiza bwa videwo.Ikimenyetso cya digitale 3 (DS3) ikoreshwa muri serivisi yo kohereza ibiro bikuru (bizwi kandi ku murongo wa T3) ikoresha kandi insinga za coaxial, zirimo 75 Ω 735 na 734. Intera yo gukwirakwiza insinga ya 735 igera kuri metero 69, mu gihe ibyo ya kabili 734 igera kuri metero 137.Umugozi wa RG6 urashobora kandi gukoreshwa mu kohereza ibimenyetso bya DS3, ariko intera yo gukwirakwiza ni ngufi.
Igishushanyo cya DB gifite ibice byuzuye bya coaxial kabili hamwe ninteko, bishobora gufasha abakiriya guhuza sisitemu yabo.Nyamuneka kanda hepfo kugirango uhitemo ibicuruzwa.Itsinda ryacu ryo kugurisha rihora hano kubwanyu.
