Nui nā mea kūpono e aʻo ai e pili ana i nā hoʻololi Ethernet. Maanei mākou e hoʻolauna nui ai pehea e pale aku ai i ka poho packet i ka mana ʻikepili ikehu o nā hoʻololi Gigabit Ethernet. ʻAʻole hiki i ka mana kahe ke hoʻomaikaʻi i ka throughput data o ka hoʻololi holoʻokoʻa, akā pale ʻo ia i ka poho packet i ka hoʻololi. ʻO Gigabit Ethernet physical layer protocol IEEE ka wehewehe ʻana i kekahi mau Gigabit Ethernet interfaces no nā media kino like ʻole, me 1000Base-CX, 1000Base-SX, 1000Base-LX, 1000Base-T.

Ma waena o lākou, ʻo 1000Base-CX kahi kikowaena i hoʻohana ʻia ma nā kaula coaxial kaulike 155Ω. ʻAʻohe huahana maoli i ka hana. ʻO 1000Base-T kahi mea hoʻohana i hiki ke hoʻohana ʻia no ka māhele 5 a i ʻole nā ​​kaula wili ʻoi aʻe. ʻO IEEE802.3ab kona kūlana. Ua hoʻokuʻu ʻia kēia maʻamau i Iune 1999, a i kēia manawa ua hoʻokuʻu ʻia nā huahana kalepa ma ka mākeke.

1000Base—SX hoʻohana i ka 850nm wavelength laser interface, he mea kūpono wale no ka multimode fiber. Hoʻohana ʻo 1000Base-LX i ka 1300nm wavelength laser interface, kūpono no ka fiber mode hoʻokahi a me ka multi-mode. Hoʻohana nui ʻia ʻo 1000Base-SX no ka ʻoihana pā kula a me ka iwi hope o ka ʻoihana.

Hoʻohana nui ʻia ʻo 1000Base-LX i nā pūnaewele wahi metropolitan. I kēia manawa ʻē aʻe kahi kikowaena metropolitan i hoʻohana nui ʻia ʻo ka lōʻihi Gigabit Ethernet switch optical interface o 1000Base-LH. ʻO ka maʻamau, hoʻohana ʻia nā lasers me nā hawewe nalu o 1300nm a i ʻole 1550nm, hiki ke piʻi aku ma mua o 50km. ʻO kahi mamao hoʻoili o 100km me ka ʻole o ka relay.

Pono e kuhikuhi ʻia, no ka mea, hāʻawi ka IEEE i ka mamao o ka hoʻouna ʻana o Gigabit Ethernet ma lalo o nā kūlana hoʻouna ʻino loa, i nā noi maoli, ʻoi aku ka mamao o ka lawe ʻana o nā huahana o nā mea hana like ʻole ma mua o nā mea maʻamau, e like me Alcatel's PowerRail 1000 The 1000Base- Hiki i ka LX interface o ka mega routing switch ke hoʻouna i 22km me ka ʻole o ka relay i ka hoʻāʻo maoli.
