Enwere ọtụtụ ihe bara uru ịmụta gbasara mgba ọkụ Ethernet. N'ebe a, anyị na-ewebata ka esi zere mfu ngwugwu na njikwa data ike nke Gigabit Ethernet switches. Njikwa ọsọ enweghị ike imeziwanye ntinye data nke ngbanwe niile, mana ọ na-ezere mfu ngwugwu na mgba ọkụ. Gigabit Ethernet physical Layer protocol IEEE na-akọwa ọtụtụ Gigabit Ethernet interfaces maka mgbasa ozi anụ ahụ dị iche iche, gụnyere 1000Base-CX, 1000Base-SX, 1000Base-LX, 1000Base-T.

N'ime ha, 1000Base-CX bụ interface eji na eriri coaxial 155Ω kwụ ọtọ. Enweghị ezigbo ngwaahịa na omume. 1000Base-T bụ interface enwere ike iji maka ụdị 5 ma ọ bụ eriri abụọ gbagọrọ agbagọ. Ọkọlọtọ ya bụ IEEE802.3ab. A tọhapụrụ ọkọlọtọ a na June 1999, ma ugbu a ka ewepụtala ngwaahịa azụmaahịa n'ahịa.

1000Base-SX na-eji 850nm wavelength laser interface, nke dabara naanị maka eriri multimode. 1000Base-LX na-eji 1300nm wavelength laser interface, dabara maka otu-mode na multi-mode fiber. A na-ejikarị 1000Base-SX eme ihe maka netwọk ụlọ akwụkwọ na ọkpụkpụ azụ azụ ụlọ ọrụ.

1000Base-LX na-ejikarị na netwọk mpaghara mepere emepe. Ugbu a netwọk mpaghara mepere emepe nke a na-ejikarị bụ Gigabit Ethernet mgba ọkụ anya dị anya nke 1000Base-LH. N'ozuzu, a na-eji lasers nwere ogologo ogologo nke 1300nm ma ọ bụ 1550nm, nke nwere ike iru ihe karịrị 50km. Ọbụna ebe nnyefe nke 100km na-enweghị ọsọ agba anọ.

Ọ dị mkpa ịkọwapụta na, n'ihi na IEEE na-enye Gigabit Ethernet nnyefe anya n'okpuru ọnọdụ mgbasa ozi kachasị njọ, na ngwa ngwa, ebe nnyefe nke ngwaahịa nke ndị na-emepụta ihe dị iche iche karịrị usoro ọkọlọtọ, dị ka Alcatel's PowerRail 1000 The 1000Base- LX interface nke mega routing switch nwere ike ibunye 22km na-enweghị relay na ule n'ezie.
