TIA568C2

TIA568C2 is a standard for the wiring of Ethernet cables, specifically for 1000BASE-T and 10GBASE-T networks. It is defined by the Telecommunications Industry Association (TIA) and the Electronic Industries Alliance (EIA) in the TIA/EIA-568-B.2-10 standard. The TIA568C2 standard specifies the pin assignments for the RJ-45 connectors used in Ethernet cables, ensuring compatibility and interoperability between different network devices.

The TIA568C2 standard uses a different pin configuration compared to the TIA568B standard. In TIA568C2, the green and orange pairs are reversed. Specifically, the green pair (pins 1 and 2) is used for transmit data, while the orange pair (pins 3 and 6) is used for receive data. This configuration is designed to reduce crosstalk and improve signal integrity, making it suitable for higher-speed Ethernet networks.

TIA568C2 is commonly used in structured cabling systems for commercial and residential buildings. It is also used in patch panels, network switches, and other networking equipment. The standard is regularly updated to accommodate advancements in Ethernet technology and to address new requirements and challenges in network design and deployment.
