Lub ntxaib - cov xov hlau stranded hauv cheeb tsam network

Kev tsis sib haum xeeb ntxaib -} stranded xov hlau (utp) thiab shield ntxaib {}} stranded xov hlau (STP). Sab nraum ntawm STP yog them los ntawm ib txheej ntawm cov khoom siv hlau los txo hluav taws xob thiab tiv thaiv cov ntaub ntawv los ntawm eavesdrodrodrodrod. UTP tsis muaj cov ntaub thaiv npog hlau, tsuas yog ib txheej ntawm insulating roj hmab pob, tus nqi pheej yig, cov network hloov tau. Feem ntau, peb siv utp tsuas yog qee lub sijhawm tshwj xeeb (xws li hluav taws xob hluav taws xob hnyav thiab muaj kev kis tau zoo) thaum STP yog siv hauv xaim. UTP tam sim no siv tau tuaj yeem faib ua peb, plaub, tsib, thiab ntau dua tsib pawg. Ntawm lawv, 3 hom UTP ua tau raws li qhov yuav tsum tau ua ntawm Ethernet (10Mbps) rau kis cov xov xwm, uas yog qhov tseem ceeb kis tau nruab nrab hauv lub network thaum ntxov. Lub 4 UTPS feem ntau tsawg siv vim tias tus qauv yog tom qab tshaj 3 utps, thiab kev xa mus tsis zoo ntxiv piv nrog 3 utps. Tsib iTPS yog qhov nruab nrab uas nyiam dua rau cov ethernet ceev (100Mbps) vim lawv tus nqi qis thiab siab zoo. Tshaj tsib utps yog siv hauv gigabet Ethernet (1000Mbps)
