Yintoni intambo yenethiwekhi ethi “UTP, FTP, SFTP”?

I-UTP — I-Unshielded Twin Idibeneyo Idibeneyo Idibeneyo.

I-STP — I-Shielded Twisted Pair Intambo yenethiwekhi ekhuselweyo.

I-FTP — Intambo yenethiwekhi yokukhusela i-aluminium foil ejijekileyo ene-foiled.

Umahluko phakathi kwe-“UTP, FTP, SFTP” kwintambo yenethiwekhi:

I-UTP: I-Unshielded Twisted Pair. I-UTP ayinazo izinto zokukhusela zesinyithi kwaye ineleya enye kuphela yesigqubuthelo serabha yokukhusela. Ixabiso layo liphantsi kwaye iyakwazi ukuguquguquka kwinethiwekhi. Iingenelo zocingo lwayo kukuba iyasebenza kakuhle kwaye ayinakubangela umlilo.

I-STP: Intambo yenethiwekhi yeShield; I-FTP yintambo yenethiwekhi ekhuselweyo yefoyile ye-aluminiyam; Eyokuqala ligama elibanzi, ngelixa eyesibini sisibizo esincinci. Kodwa eneneni, okwangoku umgca wenethiwekhi yeshielding ngumgca wenethiwekhi yeshielding yefoyile ye-aluminiyam, ngoko ke, i-STP, i-FTP iyafana. Ngokwahlukileyo kwi-UTP, i-FTP/STP lulwaleko olongezelelweyo lwefoyile ye-aluminiyam ngaphandle kwentambo engundoqo, ukuze kuncitshiswe ukuncitshiswa kwesignali. Imarike ayithandwa kangako.

I-SFTP: Intambo yenethiwekhi ekhuselweyo kabini. Ulwakhiwo lwale ntambo lusekwe kwi-foil ye-aluminium ye-FTP/STP, kunye nomaleko wenethi yobhedu eboyiweyo, eyona ingaphandle yi-PVC yangaphandle. Ngenxa yomaleko wenethi yobhedu eboyiweyo, inokunciphisa kakhulu amandla emagnethi angaphandle, ukuphazamiseka kwesignali, inokunciphisa nokuncipha kwesignali yangaphakathi, yonyuse uxinzelelo lwentambo. Ingxaki kukuba olu hlobo lokuthamba kwemisonto alulunganga kakhulu, ixabiso libiza kakhulu; Le migca idla ngokubiza kabini kune-UTP. Olu hlobo lwentambo lusetyenziswa kuphela kwiimeko ezikhethekileyo.
