Fast Ethernet (FE) yog lo lus rau Ethernet hauv kev sib txuas hauv computer, uas muab kev hloov pauv ntawm 100Mbps. Tus qauv IEEE 802.3u 100BASE-T Fast Ethernet tus qauv tau tshaj tawm los ntawm IEEE hauv xyoo 1995, thiab tus nqi xa mus ceev Ethernet yav dhau los yog 10Mbps. Tus txheej txheem ceev Ethernet suav nrog peb pawg: 100BASE-FX, 100BASE-TX, thiab 100BASE-T4. 100 qhia qhov kis tus nqi ntawm 100Mbit / s. "BASE" txhais tau tias kev sib kis ntawm baseband; Tsab ntawv tom qab qhov khiav ceev yog hais txog qhov nruab nrab kis tau tus mob nqa lub teeb liab, "T" stands rau twisted khub (tooj liab), "F" stands rau optical fiber; Cov cim kawg (tus ntawv "X", tus lej "4", thiab lwm yam) yog hais txog cov kab code siv. Cov lus hauv qab no qhia txog hom Ethernet ceev ceev.
Piv rau ceev Ethernet, Gigabit Ethernet (GE) tuaj yeem muab kev hloov pauv ntawm 1000Mbps hauv lub computer network. Gigabit Ethernet tus qauv (lub npe hu ua IEEE 802.3ab tus qauv) tau tshaj tawm los ntawm IEEE hauv xyoo 1999, tsuas yog ob peb xyoos tom qab qhov kev tshwm sim ntawm tus qauv Fast Ethernet, tab sis nws tsis tau siv dav mus txog rau xyoo 2010. Gigabit Ethernet tau txais cov qauv qauv. ntawm IEEE 803.2 Ethernet thiab CSMA / CD media access control method, uas tuaj yeem ua haujlwm hauv ib nrab duplex thiab puv duplex hom. Gigabit Ethernet muaj cov cables zoo sib xws thiab cov khoom siv rau Fast Ethernet, tab sis nws muaj ntau yam thiab kev lag luam. Nrog rau kev txhim kho txuas ntxiv ntawm Gigabit Ethernet, ntau cov ntawv tshaj tawm tau tshwm sim, xws li 40G Ethernet thiab 100G Ethernet. Gigabit Ethernet muaj cov txheej txheem sib txawv ntawm lub cev, xws li 1000BASE-X, 1000BASE-T, thiab 1000BASE-CX.
