A technician is terminating twisted-pair Ethernet cables in a office installation following the ANSI/TIA T568B wiring standard. Which of the following pin assignments correctly follow the T568B standard? (Select TWO.)

  1. Pin 1 is White/Orange and Pin 2 is Solid Orange.Answer
  2. Pin 3 is White/Green and Pin 6 is Solid Green.Answer
  3. C
    Pin 1 is White/Green and Pin 2 is Solid Green.
  4. D
    Pin 3 is White/Orange and Pin 6 is Solid Orange.

Answer

In the T568B wiring standard, Pin 1 is White/Orange, Pin 2 is Solid Orange, Pin 3 is White/Green, and Pin 6 is Solid Green.
Under the T568B wiring standard, the orange pair is assigned to pins 1 and 2 (White/Orange, Solid Orange) and the green pair is split across pins 3 and 6 (White/Green, Solid Green).

Step-by-Step Solution

1
Recall the ANSI/TIA T568B pinout standard color sequence.
The T568B sequence from Pin 1 to Pin 8 is: 1: White/Orange, 2: Orange, 3: White/Green, 4: Blue, 5: White/Blue, 6: Green, 7: White/Brown, 8: Brown.
Standard specification compliance for RJ45 cable termination.
2
Match the given options to the T568B specification.
The options specifying Pin 1 as White/Orange with Pin 2 as Solid Orange, and Pin 3 as White/Green with Pin 6 as Solid Green are verified as correct.
Accurate standard identification.
