Straight and crossover cable color code UTP has 4 twisted pairs of wires, we'll now look at the pairs to see what colour codes they have: As you can see in the picture above, the 4 pairs are labeled. Pairs 2 & 3 are used for normal 10/100Mbit networks, while Pairs 1 & 4 are reserved. In Gigabit Ethernet, all 4 pairs are used.
This tutorial explains the color coding scheme of the straight through and cross over cable. Learn what are differences between the straight through and cross over cable and which devices you can connect through these cables. This is different than straight through cable in which both ends of the cable must have the same color-coding standard at both ends, look for a Straight cable color code.
Why to Use different oF crossover cable color coding As in UTP, there are eight wires twisted together in four pairs. Straight and crossover cable color code UTP has 4 twisted pairs of wires, we'll now look at the pairs to see what colour codes they have. Ethernet Cable Color Coding Ethernet Cable Color Coding Ethernet cable which is used to connect networking devices through UTP cable and end is terminated with RJ45 connector.
In UTP cable consist of 4pair or 8 wire of different color that is used to terminate on RJ45 or 8P8C connector. By looking at a T-568A UTP Ethernet straight-thru cable and an Ethernet crossover cable with a T-568B end, we see that the TX (transmitter) pins are connected to the corresponding RX (receiver) pins, plus to plus and minus to minus. Cross-Over Wiring Using The 568A to 586B Standards The flat wiring illustration, above, shows cross-over cable wiring using the 568A color code standard as the wiring for the PC side of things and the 568B standard for wiring to the other PC.
Note that in both cases, all eight wires are shown but only four are actually needed. Green white Green Orange white Blue Blue white Orange Brown white Brown Important Note: Cross over color coding has to be different on both side of the cable as mentioned in the figure 2.1 & 2.2, unlike straight through coding, where only one color coding requires for every side of the cable.

We look at the 568A and 568B color codes, what they mean, and why they're important. ETHERNET CABLE: COLOR-CODE STANDARDS The information listed here is to assist Network Administrators in the color coding of Ethernet cables. Please be aware that modifying Ethernet cables improperly may cause loss of network connectivity.
