Nqe lus piav qhia:
Qeb 3 cable, los yog CAT3 cable yog ib hom twisted khub cable nquag siv hauv lub suab thiab cov ntaub ntawv siv. Xov tooj cable yog txhais los ntawm Electronic Industry Alliance (EIA) thiab Telecommunication Industry Association (TIA). HUIER Cable's CAT3 xov tooj cable yog tsim los ua kom tau raws li thiab/los yog tshaj cov khoom pov thawj thiab cov qauv rau EIA/TIA 568 thiab ISO/IEC 11801 specifications.
Daim ntawv thov:
Qeb 3 yog tsim rau kev kub ceev DATA / LAN kis mus txog 16 Mbps.
10 Base-T
4 Mbps Token Nplhaib
Suab
Cat3 cable tseem siv tau raws li lub suab qib cable, feem ntau yog rau POTS (Plain Old Telephone Service) thiab txawm tias qee cov ntaub ntawv tuaj yeem xa los ntawm nws (Xaiv DSL) tus nqi raug txwv txog li 10 Mbps thiab raug yuam ntau dua li cov qib niaj hnub ntawm LAN cable. Txawm hais tias kev pabcuam hauv xov tooj, yog tias koj hloov lossis txhim kho cov kab hauv koj lub tsev, koj tsis tuaj yeem mus tshawb nrhiav kev siv Cat5e lossis Cat6 cables raws li kev siv yav tom ntej thiab cov kab ntxiv tau tsim hauv.
