Until universal adoption takes place, there will most likely be many different colors used in ethernet cable colors. With patch cable color standards, the University of Wisconsin Network Services Department is leading the way through example by helping to define what colors are to be used for every cable system on their campus. Depending on the client and the application patch cable colors can vary.
The key, however, is simple — consistency. With any new system, staying with a consistent color scheme can help save time and money with implementation and maintenance, as well as prevent a lot of headaches in the future. Whether it is a Cat5, Cat5e, Cat6, or even Cat6a ethernet cable, the color code of the outside of the cable should not be confused with the internal twisted wires that have their own color code.
The outside color scheme is far more generic, simply helping to draw attention to the purpose of the connection. However, once again we see that industry standards that are used across the board are hard to come by. While the standard goes into tremendous detail for labeling and ease of identification, an actual color chart is hard to come by.
Being from a third party, this chart is for informational purposes only, to help give our readers an idea of what a network cable color chart can look like:. The deciding factor here is only as far as the design engineer choosing a given color. At Meridian, we custom create more than 70 percent of the products we produce. In fact, patch cable and crossover cable are two types of Ethernet cable, and they have the same physical characteristics.
But what on earth is the difference between the patch cable and crossover cable? With regard to these two patch cable wiring schemes, there are two different connectivity forms. The TB wiring scheme is by far the most common, though many devices support the TA wiring scheme as well.
If both ends of the patch cords are wired on the basis of one standard, it is a straight through connection. Both the standards can be used for straight through cable. If not, it is a crossover connection. Some networking applications require an Ethernet crossover cable, which has a TA connector on one end and a TB connector on the other.
This type of cable is typically used for direct computer-to-computer connections. The following section will introduce the straight through cable or patch cable and crossover cable in details. Many networking professionals use the term patch cable to refer to any kind of straight through cable. So a patch cable is often called a straight through cable. In other words, patch cable does not change or swap along its way.
Both ends use the same wiring standard: TA or TB. So both side connector A and connector B of patch cable have wire arrangement with same patch cable colors as shown in the following picture.
It allows cabling technicians to reliably predict how Ethernet cable is terminated on both ends so they can follow other technicians' work without having to guess or spend time deciphering the function and connections of each wire pair. Ethernet cable jack wiring follows the TA and TB standards.
There is no electrical difference between the TA and TB wire sequences, so neither is inherently superior. The only difference between them is how frequently they are used in a particular region or type of organization. So, your choice of color code - which one is "right" - will largely depend on the country you work in and what types of organizations you install for. Either standard is acceptable in most cases.
