Akwai abubuwa da yawa da suka cancanci koyo game da maɓallan Ethernet. Anan mun fi gabatar da yadda ake guje wa asarar fakiti a cikin sarrafa bayanan makamashi na Gigabit Ethernet switches. Ikon tafiyarwa ba zai iya inganta abubuwan da aka samar na bayanai na gabaɗayan canjin ba, amma yana guje wa asarar fakiti a cikin maɓalli. Gigabit Ethernet na zahiri Layer yarjejeniya IEEE yana bayyana musaya na Gigabit Ethernet da yawa don kafofin watsa labarai na zahiri daban-daban, gami da 1000Base-CX, 1000Base-SX, 1000Base-LX, 1000Base-T.

Daga cikin su, 1000Base-CX shine keɓancewa da aka yi amfani da shi akan madaidaitan igiyoyin coaxial 155Ω.
