What is the correct T568B pinout order for a standard 8P8C RJ45 connector?

This question tests knowledge of the T568B Ethernet termination, the widely used pinout for RJ45 jacks. In this scheme, the eight positions from left to right (with the plug’s clip facing away from you) are wired as: white/orange, orange, white/green, blue, white/blue, green, white/brown, brown. That places the orange pair on pins 1 and 2, the green pair on pins 3 and 6, the blue pair on pins 4 and 5, and the brown pair on pins 7 and 8. This arrangement is standard for new installations and keeps all four twisted pairs correctly paired end-to-end, which is essential for reliable 10/100/1000BASE-T operation and compatibility with typical networking gear. Other sequences would misplace twisted pairs—for example, switching the orange and green pairs or moving a color to a non-maired pin—so they wouldn’t conform to the established wiring standard.
