Ethernet yihuta (FE) nijambo rya Ethernet muguhuza mudasobwa, itanga igipimo cyo kohereza 100Mbps. IEEE 802.3u 100BASE-T Byihuta Ethernet yashyizweho na IEEE kumugaragaro mu 1995, kandi umuvuduko wa Ethernet wihuta wari 10Mbps. Igipimo cyihuta cya Ethernet gikubiyemo ibyiciro bitatu: 100BASE-FX, 100BASE-TX, na 100BASE-T4. 100 yerekana igipimo cyo kohereza 100Mbit / s. "BASE" bisobanura kohereza baseband; Inyuguti nyuma yumurongo werekana uburyo bwo kohereza butwara ibimenyetso, "T" bisobanura guhuza (umuringa), "F" bisobanura fibre optique; Inyuguti ya nyuma (inyuguti "X", umubare "4", nibindi) bivuga uburyo bw'imirongo ikoreshwa. Imbonerahamwe ikurikira irerekana ubwoko bwihuse bwa Ethernet.
Ugereranije na Ethernet yihuta, Gigabit Ethernet (GE) irashobora gutanga igipimo cyo kohereza 1000Mbps mumurongo wa mudasobwa. Igipimo cya Ethernet ya Gigabit (kizwi ku izina rya IEEE 802.3ab) cyasohowe ku mugaragaro na IEEE mu 1999, nyuma yimyaka mike nyuma y’igipimo cyihuta cya Ethernet, ariko nticyakoreshejwe cyane kugeza mu mwaka wa 2010. Gigabit Ethernet yakoresheje imiterere yikadiri. ya IEEE 803.2 Ethernet hamwe na CSMA / CD itangazamakuru uburyo bwo kugenzura uburyo, bushobora gukora muri kimwe cya kabiri cya duplex nuburyo bwuzuye bwa duplex. Gigabit Ethernet ifite insinga nibikoresho bisa na Ethernet yihuta, ariko birahinduka kandi byubukungu. Hamwe niterambere rihoraho rya Gigabit Ethernet, hagaragaye izindi verisiyo zateye imbere, nka 40G Ethernet na 100G Ethernet. Gigabit Ethernet ifite ibipimo ngenderwaho bitandukanye, nka 1000BASE-X, 1000BASE-T, na 1000BASE-CX.
