Yafakwa Cable - ukuthembeka ngexabiso elifikelelekayo

Kuba uluntu iinkcukacha mihla yorhwebo ebaluleke kakhulu emarikeni iintlobo zemveliso, kuqinisekiswe ukudalwa ezikumgangatho ophezulu kwaye zithembekile eendaba iinkcukacha zonxibelelwano. Enye yazo intambo yafakwa. Wasebenza kakuhle xa asetyenziselwa iinjongo ezahlukeneyo.

Intambo yafakwa yedijithali sisetyenziswa ngokubanzi kwiinkalo ezininzi zezinto ezenziwa luluntu. Ngokukodwa, lisetyenziswa ukuze adlulisele satellite kunye video. Oku kungenxa yokuba kubhaliwe udalelwe ukuze adlulisele pulses ophezulu rhoqo. design awodwa ivumela ukufikelela ukuziswa mgangatho uphezulu kuzo naziphi na iimpawu ngaphandle ilahleko. Kulo mzekelo, ukuhanjiswa kolwazi zinokusasazwa imigama emide kunye eziphango kancinane okanye hayi.

Ngokubanzi, intambo yafakwa unalo isakhiwo zilandelayo: leyo phakathi umqhubi (ukusekwa, ngokuqhelekileyo zobhedu) sibekwe polyethylene ezixineneyo ngokubhijela ukuba iipropati Heating kwaye songeza ephothiweyo umnatha yeengcingo zesinyithi. Ukusuka ngaphezu kokuba ehlanganiswa i urhangqo zokwambathisa of polyethylene okanye Polyvinyl chloride.

intambo yafakwa, kwakunye nezinye transmission emzimbeni medium, kukho inani iimpawu ezithile. Ngoko ke kuyimfuneko kwasekuqaleni bazi ngokucacileyo ukuba yintoni injongo, yintoni okusingqongileyo kuya kusetyenziswa, yaye kuphela emva koko ukhethe uhlobo iimpawu ezininzi ezifanelekileyo.

Umzekelo, intambo yafakwa ngokucupha ividiyo kumele ube mihlaba ilandelayo:

1. Uthunyelwe kangangoko kunokwenzeka spectrum njalo.
2. impembelelo Ubuncinane kwi wesekethe lokuphumelela elandelayo apho umbane ethunyelwayo.
3. Lokumelana ephezulu kakhulu kwiimpembelelo yangaphandle.
4. Ukhuseleko ekuphazanyisweni.

Kwakhona kukho into ebalulekileyo kukuba kwinkcaso esezantsi-frequency ingxolo, njengoko oku ethile ephambili kwimveliso enjalo - kuba sengozini ukuva kwi ezitsho eliphantsi.

Intambo yafakwa ngoyena ngokuqhelekileyo esetyenziselwa ukudluliselwa kwedata phakathi ukwamkelwa kunye nezixhobo yokudlulisela. Nguye yenye yeendlela ezininzi eziqhelekileyo ukuze adlulisele imiqondiso umabonwakude neevidiyo. Ubukho balo ayikho ubuncinane ngenxa cheapness isalamane.

Kukho iqela elikhulu kweentlobo ezahlukeneyo yafakwa. Umahluko ephambili kuxhomekeke ubunjalo bomzimba. Ngelo xesha linye kubalulekile ukukhumbula ukuba umgaqo amanyathelo iintlobo ezahlukeneyo imveliso efanayo.

Ukuba ucinga ukufaka naphi (ekhaya okanye kwi-ofisi) inkqubo ivideo zokucupha, eyiyo zothumelo medium iya kuba USB kanye yafakwa. Uya kufumana i inkqubo esebenza ethembekileyo ngesixa elincinane ngokwentelekiso imali. Kwaye ukwanda kunye nenani nemibingelelo kwimarike ukuvumela ukuba ukhethe imveliso nefanele kanye ukuba iimfuno zakho. Oku kuya kukunceda ukuba amaphondo aqalise ngenkqubo ye nayiphi nokuba eyayizalwa.
