Gigabit Ethernet, also known as 1000BASE-T, uses twisted-pair copper cables to transmit data at a rate of 1 gigabit per second (Gbps). The most common used cable for Gigabit Ethernet is Category 5e (Cat5e) or Category 6 (Cat6) cable. These cables have four pairs of twisted wires, and each pair is used for transmitting and gavimas data. The pairs used for Gigabit Ethernet are:
Pora 1: Perdavimas ir Gavimas On Pins 1 ir 2
Viela 1 (Balta/Orange): Transmit plius
Wire 2 (Oranžinė): Perdavimas -
Wire 3 (Balta/Green): Gauti plius
Wire 6 (Žalia): Gauti -
Pair 2: Transmitavimas ir Gavimas on pins 3 ir 6
Viela 3 (Balta/Green): Perdavimas plius
Wire 6 (Žalia): Perdavimas -
Wire 1 (Balta/Orange): Gauti plius
Wire 2 (Oranžinė): Gauti -
Pair 3: Transmitavimas ir Gavimas on pins 4 ir 5
Viela 4 (Balta/Blue): Transmit plius
Wire 5 (Mėlyna): Perdavimas -
Wire 7 (Balta/Brown): Gauti plius
Wire 8 (Ruda): Gauti -
Pair 4: Transmitavimas ir Gavimas on pins 7 and 8
Viela 7 (Balta/Brown): Transmit plius
Wire 8 (Ruda): Perdavimas -
Wire 4 (Balta/Blue): Gauti plius
Wire 5 (Mėlyna): Gauti -
These pairs are used in a balanced configuration, with one wire in each pair carrying the positive (transmit or receive) signal and the other wire carrying the negative (transmit or receive) signal. By using a twisted-pair configuration, Gigabit Ethernet reduces electromagnetic interference and enables reliable data transmission at high speeds.
It's important to note that these pairs are used for Gigabit Ethernet over twisted-pair copper cables. Other types of Ethernet standards, such as 10 Gigabit Ethernet (10GBASE-T) or higher speeds, may use different wiring configurations or different types of cables, such as Cat6a or Cat7, to support higher data rates.
