Which of the following has color codes that match on both ends (e.g. orange-white, orange, green- white, blue, blue-white, green, brown-white, brown)?

A straight-through cable is wired pin-to-pin with the same pinout on both ends, meaning each color-coded wire (e.g., orange-white on pin 1) appears on the same pin at both ends. This is used to connect unlike devices such as a PC to a switch, and the matching color sequence on both ends distinguishes it from a crossover cable.

A UTP crossover cable intentionally swaps transmit and receive pairs between ends, so the color codes do not match on both sides.

Multi-mode fiber uses optical strands and has no copper color codes; connectors are identified by type (e.g., LC, SC), not wire colors.

Single-mode fiber also uses optical strands and does not have copper wire color coding.
