El cable UTP Iwumthombo osetshenziswa kabanzi emhlabeni wezokuxhumana. Kuyizinhlobonhlobo zekhebula elisontekile elisontekile (yingakho igama layo: UTP, isifinyezo ngesiNgisi sa Unshielded Twisted Pair) ekhona ezinhlotsheni eziningi zokufakwa.
Lolu hlobo oluthile lwekhebula luvelele inani elikhulu lolwazi olungadluliswa, así como por la velocidad y la precisión lokhu kudlulisa okwenziwa ngakho.
Ukuze siqonde ngokugcwele ukubaluleka kwalolu hlobo lwekhebula, kuyadingeka ukuthi sibuyele emuva kancane emlandweni. Siya ukuqala kwefoni, lapho ukufakwa kwezintambo zezintambo zangaphandle ezinde kudingekile. Ezigxotsheni zocingo, zafakwa amabha lapho ikhebula lokudlulisela liqondane nekhebula lamandla kagesi. Lesi sakhiwo sisabonakala emasimini nasemadolobheni ethu.
Inkinga ngalokhu kumiswa ukuthi ugesi ubangele ukuphazamiseka esignali yocingo. Ukuxazulula lokhu, okuthiwa ikhebula lokushintsha, lapho ikhebuli ye-UTP iwukuhluka okuguquliwe. Lokhu kuluka yikho okunomthelela ekwehliseni ukuphazamiseka kwe-electromagnetic, okuhumushela kukhwalithi yesignali ephezulu.
Izintambo ezimbili ezisontekile zaqala ukusetshenziswa ezinhlelweni zocingo zase-United States ngasekupheleni kwekhulu le-19. Njengamanje bahamba ibanga lezigidigidi zamakhilomitha emhlabeni jikelele. Iningi ledatha yokuxhumana kwe-inthanethi lisebenzisa lezi zintambo.
Injani i-UTP Cable?
Isihluthulelo sokusebenziseka kwezintambo ze-UTP zokusetshenziswa ezihloselwe zona ukulele kuzo ukumisa noma ukwakheka. Kufanele kuqashelwe ukuthi, ngaphandle kwe- Ikhava ye-PVC esetshenziselwa ukumboza, abanalo noma yiluphi uhlobo lokuvikela okukhethekile. Ngaphakathi, asitholi noma iyiphi ingxenye yokuhlukanisa phakathi kwezintambo.
Como su nombre indica, se trata de amapheya ezintambo eziphambana ngendlela ye-spiral loop, njengokungathi a trenza. Intambo yomqhubi ngamunye yenziwe ngethusi noma nge-aluminium futhi ifika imbozwe ngesivikeli sepulasitiki esisodwa.
Isakhiwo sayo esiyisisekelo yilesi esilandelayo:
- Pares trenzados: Amapheya amane ezintambo zethusi eziphothene ndawonye.
- Aislante: emboza intambo yethusi ngayinye, into ebalulekile ukugwema amasekhethi amafushane.
- Cubierta protectora- Isendlalelo sangaphandle se-PVC esivikela izintambo eziboshiwe kuyilapho sinikeza ukuguquguquka kwentambo.
Kuye ngokuthi inhloso yabo izoba yini, lezi zintambo Angabamba amapheya afika kwangu-100 noma ngaphezulu.. Ikakhulukazi lawo ayesetshenziselwa ukumboza amabanga amade phakathi kwamazwe noma amazwekazi, ngaphambi kokuvela kwe-fiber optics emhlabeni wezokuxhumana.
Ngenxa yalezi zici (ukuba lula, ukufinyeleleka...), ukusetshenziswa kwentambo ye-UTP kunezindleko ezingabizi kakhulu kunezinye izinketho eziningi, yingakho Ingenye yezindlela ezivame kakhulu lapho udala izinhlelo zokuxhuma ezisebenza kahle nezivikelekile.
Tipos de cable UTP
Kunezinhlobo ezahlukene zezintambo ze-UTP kuye ngekhwalithi namandla okudlulisa abakunikezayo. Izinga lekhwalithi lisukela kupheya eyodwa yezintambo zezwi, ezisetshenziswa ekudluliselweni kocingo okuyisisekelo, kuya kukhebuli yeleveli 5 efinyelela amazinga okudlulisa afika ku-100 MBits/s. Lesi yisigaba:
- Isigaba 1: Izwi (Intambo Yocingo).
- Isigaba 2: Idatha ku-4 Mbps (LocalTalk).
- Isigaba 3: Idatha ku-10 Mbps (Ethernet).
- Isigaba 4: Idatha ku-20 Mbps/16 Mbps Token Ring.
- Isigaba 5: Idatha ku-100 Mbps (i-Fast Ethernet).
Lezi zintambo zikhonza uhlobo lwe Izixhumi ezibizwa nge-RJ (Registered Jack). Ngaphakathi kwalesi sigaba sezixhumi kukhona, futhi, amakhono ahlukene atholakalayo.
Ukusetshenziswa kwezintambo ze-UTP
Kunezinhlobonhlobo zezinhlelo zokusebenza zezintambo ze-UTP kumanethiwekhi ekhompyutha. Lezi ezinye eziphawuleka kakhulu:
- Ukuxhumana phakathi kwamakhompyutha namadivayisi enethiwekhi: Yikhebula elisetshenziswa kakhulu ukuxhuma amakhompyutha, amaphrinta, amarutha namanye amadivayisi enethiwekhi.
- Domótica: Ivumela ukuxhumeka kwazo zonke izinhlobo zamadivayisi ezishintshayo ekhaya njengama-smart thermostats.
- Amanethiwekhi endawo (LAN): Ikhebula le-UTP likhona kumanethiwekhi amaningi endawo, kungaba sekhaya noma ehhovisi.
- Sistemas de seguridad: amakhamera okuqapha, ama-alamu, njll.
- Ucingo: Isetshenziselwa ikakhulukazi ukuxhumana ngocingo lwasendlini kanye VoIP.
I-UTP: Izinzuzo kanye nokubi
Nakuba kube yisixazululo esihle iminyaka engaphezu kwekhulu, Ikhebula le-UTP linazo zombili izici ezinhle nezingezinhle. Kutuswa ukuzazi ukuze uhlole ukuthi zisinikeza ini ngempela emkhakheni wezinsiza zokuxhumana namuhla.
Singafingqa okwakho izinzuzo en los siguientes puntos:
- Bajo coste. Kuyindlela eshibhile uma iqhathaniswa, isibonelo, nefiber optics.
- Ukufakwa kalula nokuphatha. Ngisho nezandla ezingenalwazi.
- Amplia disponibilidad y versatilidad. Ingathengwa kunoma yisiphi isitolo futhi ilungele izinhlobo eziningi zokufakwa.
Ngokuphathelene ne- izinkinga, nayo enazo, okulandelayo kufanelekile ukubalula:
- Ukuba sengozini kokuphazanyiswa yi-electromagnetic, ehlisa izinga lesignali.
- Alcance limitado. Ubude obukhulu bekhebula, uma ufuna ukuba nekhwalithi yesignali enhle, cishe amamitha ayi-100.
- Umkhawulokudonsa olinganiselwe, ephansi kakhulu kunaleyo ye-fiber optics. Lokhu kuyenza ingafaneleki ezinhlelweni ezidinga isivinini esikhulu sokudlulisa.
