Iyini intambo yenethiwekhi ye-“UTP, FTP, SFTP”?

I-UTP — Engavikelekile Esontekile Ebhanqiwe Ngamatanisiwe.

I-STP — Intambo yenethiwekhi Evikelekile Esontekile Evikelekile.

I-FTP - Ikhebula lenethiwekhi ye-Foiled Twisted Twisted aluminium foil evikela inethiwekhi.

Umehluko phakathi kwe-“UTP, FTP, SFTP” kukhebula yenethiwekhi:

I-UTP: I-Unshielded Twisted Pair.I-UTP ayinakho okokuvikela kwensimbi kanye nongqimba olulodwa kuphela lwesembozo senjoloba evikelayo.Ishibhile futhi ivumelana nezimo kunethiwekhi.Izinzuzo zezintambo zayo ziwumphumela omuhle we-flame retardant futhi mancane amathuba okuba kubangele umlilo.

I-STP: Intambo yenethiwekhi yeShield;I-FTP intambo yenethiwekhi evikelekile ye-aluminium foil ;Eyokuqala yigama elibanzi, kanti lena yokugcina iyibizo elincane.Kodwa empeleni, okwamanje umugqa wenethiwekhi ovikelayo umugqa wenethiwekhi ovikela ucwecwe lwe-aluminium, ngakho, i-STP, i-FTP empeleni iyafana. Ngokuphambene ne-UTP, i-FTP/STP imane nje iyisendlalelo esengeziwe se-aluminium foil ngaphandle kwentambo ewumgogodla, ukuze kwehliswe ukuncisha isignali.Imakethe ayidumile kangako.

I-SFTP: Intambo yenethiwekhi evikelwe kabili.Isakhiwo salolu cingo sisekelwe kucwecwe lwe-aluminium ye-FTP/STP, kanye nongqimba lwenethi eboshwe ngethusi eliboshwe, ngaphandle kakhulu i-PVC yangaphandle. ukuphazamiseka, kungase futhi kunciphise ukuncipha kwesignali yangaphakathi, kukhuphule ukushuba kwentambo.Ububi ukuthi lolu hlobo lokuthambile kwentambo lubi kakhulu, izindleko ziyabiza;Le migqa ngokuvamile ibiza ngokuphindwe kabili kune-UTP.Lolu hlobo lwentambo lusetshenziswa kuphela ezimeni ezikhethekile.
