Kunezinto eziningi okufanele uzifunde mayelana nokushintsha kwe-Ethernet. Lapha sethula ikakhulukazi indlela yokugwema ukulahleka kwephakethe ekulawuleni idatha yamandla okushintshwa kwe-Gigabit Ethernet. Ukulawula ukugeleza akukwazi ukuthuthukisa ukuphuma kwedatha kwayo yonke iswishi, kodwa kugwema ukulahleka kwephakethe kuswishi. Iphrothokholi yesingqimba somzimba se-Gigabit Ethernet i-IEEE ichaza ukuxhumana okumbalwa kwe-Gigabit Ethernet yemidiya ehlukile ebonakalayo, okuhlanganisa i-1000Base-CX, 1000Base-SX, 1000Base-LX, 1000Base-T.

Phakathi kwazo, i-1000Base-CX iyisixhumi esibonakalayo esisetshenziswa kumakhebuli angama-coaxial abhalansi angu-155Ω. Awukho umkhiqizo wangempela ekusebenzeni. I-1000Base-T iyisixhumi esibonakalayo esingasetshenziswa esigabeni sesi-5 noma izintambo ezisontekile eziphezulu. Izinga layo yi-IEEE802.3ab. Leli zinga lisanda kukhishwa ngoJuni 1999, futhi manje imikhiqizo yezohwebo isanda kwethulwa emakethe.

I-1000Base—SX isebenzisa isixhumi esibonakalayo se-laser ye-wavelength engu-850nm, elungele kuphela i-multimode fiber. I-1000Base-LX isebenzisa isixhumi esibonakalayo se-laser ye-wavelength engu-1300nm, ifanele i-fiber yemodi eyodwa kanye nemodi eminingi. I-1000Base-SX isetshenziselwa kakhulu inethiwekhi yekhampasi kanye nomgogodla wenethiwekhi yebhizinisi.

I-1000Base-LX isetshenziswa kakhulu kumanethiwekhi endawo yedolobha elikhulu. Manje enye inethiwekhi yendawo yedolobha elikhulu esetshenziswa kabanzi i-Gigabit Ethernet switch optical interface ye-1000Base-LH yamabanga amade. Ngokuvamile, kusetshenziswa ama-laser anamaza wamaza angu-1300nm noma angu-1550nm, angafinyelela ngaphezu kuka-50km. Ngisho nebanga lika-100km lika-gearbox ngaphandle kwe-relay.

Kudingeka kuphawulwe ukuthi, ngenxa yokuthi i-IEEE inikeza ibanga lokudlulisela le-Gigabit Ethernet ngaphansi kwezimo ezimbi kakhulu zokudlulisela, ezinhlelweni zokusebenza zangempela, ibanga lokudlulisela lemikhiqizo yabakhiqizi abahlukahlukene lidlula kakhulu imibandela evamile, njenge-Alcatel's PowerRail 1000 The 1000Base- I-interface ye-LX ye-mega routing switch ingadlulisela i-22km ngaphandle kokudluliselwa ekuhlolweni kwangempela.
