Nrhiav rau lub zoo meej UTP cable rau koj network xav tau kev pab? Tsis txhob yig tau ntxiv lawm! Muaj ntau ntau hom UTP cable, los yog unshielded twisted khub cable, thiab txhua hom muaj nws tus kheej zoo thiab qhov tsis zoo. Cia peb tshawb nrhiav qhov sib txawv UTP cable hom thiab lawv cov yam ntxwv tshwj xeeb los pab koj txiav txim siab paub.
Ua ntej, peb muaj Cat5e cable. Cov cables no tau siv dav hauv Ethernet kev sib txuas thiab muab kev ruaj ntseg zoo rau feem ntau cov ntawv thov network. Lawv muaj peev xwm txhawb nqa cov ntaub ntawv hloov ceev mus txog 1 Gbps thiab yog tus nqi pheej yig. Txawm li cas los xij, Cat5e cable yuav tsis haum rau cov ntawv thov kev kub ceev vim muaj kev txwv bandwidth.
Tom ntej no, peb muaj Cat6 cable. Cov kab hluav taws xob no yog qhov hloov kho tshiab ntawm Cat5e, muab cov ntaub ntawv hloov pauv nrawm dua thiab zoo tagnrho rau kev xav tau ib puag ncig network. Nrog kev ruaj ntseg thiab kev ua tau zoo dua, Cat6 cables yog qhov kev xaiv nrov ntawm cov lag luam thiab cov koom haum. Txawm li cas los xij, lawv yog me ntsis kim dua Cat5e cables.
Tom ntej no yog Cat6a cables, tsim los txhawb kev hloov cov ntaub ntawv ntau dua thiab muab kev ruaj ntseg zoo dua thiab kev ua haujlwm ntev dua. Lawv yog cov zoo tagnrho rau high-ceev network daim ntaub ntawv thiab muab zoo heev electromagnetic cuam tshuam (EMI) tiv thaiv. Txawm li cas los xij, nce kev ua tau zoo los nrog tus nqi siab dua.
Thaum kawg, peb muaj Cat7 cable. Cov cables no nyiam dua rau kev sib txuas ceev ceev. Nrog kev ruaj ntseg zoo thiab kev ua tau zoo, Cat7 cables muaj peev xwm txhawb nqa cov ntaub ntawv hloov ceev mus txog 10 Gbps nyob rau qhov ntev. Lawv kuj muab kev tiv thaiv EMI zoo heev. Txawm li cas los xij, Cat7 cable yog qhov kev xaiv kim tshaj plaws ntawm UTP cables.
Hauv cov ntsiab lus, koj qhov kev xav tau tshwj xeeb network, peev nyiaj, thiab kev xav tau kev ua haujlwm yuav tsum raug txiav txim siab thaum xaiv hom UTP cable zoo. Txawm hais tias koj xaiv tus nqi pheej yig Cat5e, Cat6 ruaj khov dua, ua haujlwm siab Cat6a, lossis sab saum toj-ntawm-tus-kab Cat7, txhua hom UTP cable muaj nws qhov zoo thiab qhov tsis zoo. Yog li ntawd, ntsuas koj cov kev xaiv ua tib zoo thiab xaiv UTP cable hom uas haum rau koj lub network xav tau.
