Fast Ethernet (FE) ndiro izwi reEthernet mukombuta network, iyo inopa mwero wekutamisa we100Mbps. Iyo IEEE 802.3u 100BASE-T Fast Ethernet standard yakaunzwa zviri pamutemo neIEEE muna 1995, uye mwero wekufambisa wekukurumidza Ethernet waimbova 10Mbps. Iyo Fast Ethernet chiyero inosanganisira matatu madiki-mapoka: 100BASE-FX, 100BASE-TX, uye 100BASE-T4. 100 inoratidza mwero wekutapurirana we100Mbit/s. "BASE" zvinoreva baseband transmission; Tsamba iri mushure medhishi inoreva nzira yekufambisa inotakura chiratidzo, "T" inomirira maviri akamonyoroka (copper), "F" inomirira optical fiber; Chimiro chekupedzisira (tsamba "X", nhamba "4", nezvimwewo) zvinoreva nzira yekodhi yemutsara inoshandiswa. Tafura inotevera inoratidza akajairika kukurumidza Ethernet marudzi.
Kuenzaniswa neEthernet inomhanya, Gigabit Ethernet (GE) inogona kupa chiyero chekufambisa che1000Mbps mune network network. Iyo Gigabit Ethernet standard (inozivikanwa seIEEE 802.3ab standard) yakadhindwa zviri pamutemo neIEEE muna 1999, makore mashoma mushure mekuuya kweFast Ethernet standard, asi haina kushandiswa zvakanyanya kusvika kuma 2010. Gigabit Ethernet inotora iyo furemu fomati. yeIEEE 803.2 Ethernet uye CSMA/CD midhiya yekuwana nzira yekudzora nzira, inogona kushanda muhafu duplex uye yakazara duplex mode. Gigabit Ethernet ine tambo dzakafanana uye zvishandiso kuFast Ethernet, asi inonyanya kuenderana uye ine mari. Nekuenderera mberi kweGigabit Ethernet, dzimwe shanduro dzepamusoro dzakaonekwa, dzakadai se40G Ethernet uye 100G Ethernet. Gigabit Ethernet ine akasiyana emuviri layer zviyero, se1000BASE-X, 1000BASE-T, uye 1000BASE-CX.
