best phone solution
Posted on Oct 25, 2021


Ethernet cable color codes identify eight wires in cat 5, cat 5e, or Cat 6 cables. These cables are used for internet access in homes and offices (most common).

Ethernet cable color code is the combination of 4 pairs of wires twisted together. Identifying each pair is necessary because it carries different data through them. The cable should be labeled at both ends to identify the color code of each wire. The standard color code for four pairs in cat 5, cat 5e, and cat six cables is as follows:

Pair 1 = White/Green Pair 2 = Green/Orange Pair 3 = Blue/Blue-White Pair 4 = Orange/Brown

Standard color for each pair should be followed while labeling both ends of the cable. If only one end is tagged, then it will be a little confusing. Some people follow different color codes, which is not standard, and some do not follow any color code. For labeling purposes, use a wire label, or you can also create your labels.
