Color Coding Cat 5e and Cat 6 Cable Straight Through and Cross Over

When the RJ-45 connectors first came into use, they were primarily used for telephones. The great advances in technology created a need for another size connector and the RJ-45 was adapted to fit. There are 2 different RJ-45 connector sizes available:

1. for Cat 5 cable and

2. for Cat 6 cable. 

You have to make sure which one suited to their job. Basic difference is, the Cat 6 connector is larger than the Cat 5 connector.

Crimping Tool

There are also two types of Color Coding for Cat 5e and Cat 6 (Crimping RJ-45):

1. Straight Through (for Switch or Hub)

2. Cross Over (where 2 computers connected with each other without switch or hub)

1. Straight Through Color Coding (for Switch or Hub)

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.

Straight-through UTP Cables.

Use a straight-through cable when connecting different types of network devices.

A straight-through cable has connectors on each end that are terminated the same in accordance with either the T568A or T568B standards.

Identifying the cable standard used allows you to determine if you have the right cable for the job. More importantly, it is a common practice to use the same color codes throughout the LAN for consistency in documentation.

Note:

Use straight-through cables for the following connections:

a.  Switch to a router Ethernet port
b.  Computer to switch
c.  Computer to hub
