Ob chav tawm ntawm cov xov hlau tau faib raws li ISO / IEC 11801 tus qauv. Muaj peb hom kab, tsib hom kab thiab tsib hom kab, rau hom kab, xya hom kab thiab xya hom kab. Tus qub yog nyias hauv txoj kab uas hla thiab tom kawg yog tuab hauv lub taub. Tus qauv yog raws li hauv qab no:
Ib txoj kab: feem ntau yog siv rau kis lub suab (tus qauv siv rau cov xov tooj ua ntej xyoo 1980s), uas yog txawv ntawm cov ntaub ntawv kis thiab tau raug tshem tawm los ntawm tus qauv.
Hom 2 kab: Kev sib txuas lus yog 1mHz, uas yog siv rau kev sib kis suab thiab cov ntaub ntawv sib kis nrog qhov kis tau ntau tshaj plaws ntawm 4Mbps. Nws yog feem ntau pom nyob rau hauv lub qub token nplhaib uas siv 4Mbps Txheem Token hloov cov txheej txheem, uas tau raug tshem tawm los ntawm tus qauv.
Peb hom cable: Tus Hloov Chaw Xa Khoom ntawm cov cable no yog 16mHz, uas yog siv rau kev sib kis suab thiab cov ntaub ntawv sib kis nrog tus nqi tshaj plaws ntawm 10Mbps. Nws yog tsuas yog siv rau 10base- t.
Plaub hom kab ke: tus pas ntsuas hluav taws xob ntawm hom kev sib kis ntawm lub suab sib kis no ntawm 16mbs} 2} {t / 100 t, uas tau raug tshem tawm los ntawm tus qauv.
Tsib hom cables: hom cable no nce winding ntom ntom, thiab nws cov kev xa nqi bandwidth yog 100mhz. Nws yog siv rau kev sib kis suab thiab cov ntaub ntawv sib kis nrog qhov kis tau ntau tshaj plaws ntawm tus nqi ntawm 100mbps. Nws yog tsuas yog siv rau 100base - t thiab 10base {{{t networks, thiab tau hloov los ntawm ntau tshaj tsib hom cable.
