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.

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.
Thanks & Blessing be on you all!
