Iyini ikhebula lenethiwekhi elithi “UTP, FTP, SFTP”?

I-UTP — Okungavikelwe Okusontekile Okubhangqiwe Okusontekile Okubhangqiwe.

I-STP — I-Pair Esontekile Evikelwe Ikhebula lenethiwekhi elivikelwe.

I-FTP — Ikhebula lenethiwekhi yokuvikela i-foil ye-aluminium egobile.

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

I-UTP: I-Unshielded Twisted Pair. I-UTP ayinazo izinto zokuvikela insimbi futhi inesendlalelo esisodwa kuphela sesembozo serabha esivikelayo. Ishibhile futhi iguquguquka kunethiwekhi. Izinzuzo zokuxhuma kwayo ukuthi inamandla okuvimbela ilangabi futhi ayinawo amathuba okuba ibangele umlilo.

I-STP: Ikhebula lenethiwekhi yesivikelo; I-FTP iyikhebula lenethiwekhi elivikelwe nge-aluminium foil; Elokuqala liyigama elibanzi, kanti elokugcina liyibizo elincane. Kodwa empeleni, okwamanje umugqa wenethiwekhi yokuvikela uwumugqa wenethiwekhi yokuvikela nge-aluminium foil, ngakho-ke, i-STP, i-FTP empeleni iyafana. Ngokungafani ne-UTP, i-FTP/STP imane nje ingqimba eyengeziwe ye-aluminium foil ngaphandle kwentambo eyinhloko, ukuze kuncishiswe ukuncishiswa kwesignali. Imakethe ayithandwa kakhulu.

I-SFTP: Ikhebula lenethiwekhi elivikelwe kabili. Isakhiwo sale ntambo sisekelwe ku-foil ye-aluminium ye-FTP/STP, kanye nesendlalelo senethi yethusi elilukiwe ethini, iningi langaphandle yi-quilt yangaphandle ye-PVC. Ngenxa yesendlalelo senethi yethusi elilukiwe ethini, kunganciphisa kakhulu insimu yamagnetic yangaphandle, ukuphazamiseka kwesignali, kunganciphisa nokuncipha kwesignali yangaphakathi, kwandise ukucindezeleka kwekhebula. Ububi ukuthi lolu hlobo lokuthamba kwentambo lubi kakhulu, izindleko zibiza kakhulu; Le migqa ivame ukubiza kabili kune-UTP. Lolu hlobo lwentambo lusetshenziswa kuphela ezimweni ezikhethekile.
