Which wiring standard uses White/Orange as its first color code?

The wiring standard that uses White/Orange as its first color code is T568B. This standard is primarily used in structured cabling and is widely implemented in Ethernet networks. In the T568B wiring scheme, White/Orange is designated as the first pair, corresponding to the transmit data and is critical in ensuring proper communication between network devices.

T568B is often preferred in commercial installations and has become the most widely used standard in the United States. The first color code assignment is essential for maintaining proper pin alignment and consistent performance across the network. Understanding these wiring standards is crucial for any Information Technology Specialist, as improper wiring can lead to connectivity issues and network failures.
