Pali zinthu zambiri zomwe muyenera kuphunzira pakusintha kwa Ethernet. Apa tikuwonetsa momwe tingapewere kutayika kwa paketi pakuwongolera kwamphamvu kwa ma switch a Gigabit Ethernet. Kuwongolera koyenda sikungawongolere kuchuluka kwa data pakusintha konse, koma kumapewa kutayika kwa paketi mu switch. Gigabit Ethernet physical layer protocol IEEE imatanthauzira malo angapo a Gigabit Ethernet pazama media osiyanasiyana, kuphatikiza 1000Base-CX, 1000Base-SX, 1000Base-LX, 1000Base-T.

Mwa iwo, 1000Base-CX ndi mawonekedwe omwe amagwiritsidwa ntchito pa 155Ω zingwe zofananira za coaxial. Palibe mankhwala enieni muzochita. 1000Base-T ndi mawonekedwe omwe angagwiritsidwe ntchito pagulu 5 kapena zingwe zapamwamba zopotoka. Muyezo wake ndi IEEE802.3ab. Muyezo uwu udatulutsidwa kumene mu June 1999, ndipo tsopano zinthu zamalonda zangotulutsidwa kumene pamsika.

1000Base-SX imagwiritsa ntchito mawonekedwe a laser a 850nm, omwe amangoyenera ma multimode fiber. 1000Base-LX imagwiritsa ntchito mawonekedwe a laser a 1300nm wavelength, oyenera single-mode ndi multimode fiber. 1000Base-SX imagwiritsidwa ntchito makamaka pamaneti amasukulu komanso msana wamabizinesi.

1000Base-LX imagwiritsidwa ntchito makamaka pama network amderali. Tsopano maukonde ena omwe amagwiritsidwa ntchito kwambiri mumzindawu ndi mawonekedwe aatali a Gigabit Ethernet switch optical mawonekedwe a 1000Base-LH. Nthawi zambiri, ma laser okhala ndi mafunde a 1300nm kapena 1550nm amagwiritsidwa ntchito, omwe amatha kupitilira 50km. Ngakhale kufala mtunda wa 100km popanda kuponyera.

Ziyenera kunenedwa kuti, chifukwa IEEE imapereka mtunda wotumizira wa Gigabit Efaneti pansi pazovuta kwambiri zotumizira, m'mapulogalamu enieni, mtunda wotumizira wa zinthu zopangidwa ndi opanga osiyanasiyana umaposa zomwe zimaperekedwa, monga Nokia's PowerRail 1000 The 1000Base- Mawonekedwe a LX a mega routing switch amatha kufalitsa 22km popanda kubwereza pamayeso enieni.
