Can I Use the Red Blue and Green Plugs for Internet

At Meridian, we are asked all the time if the colors for different wires and cables follow any industry standard. The Institute of Electrical and Electronics Engineers (IEEE), a worldwide trade association, does, in fact, issue guidance for standardization in electrical design, but the key point is that their standards don't actually get into the details of specifying cable colors as they pertain to a specific purpose or function. Rather, the push for standardization in this arena has been more on the private industry side, with the telecommunications industry leading the way. Here, we'll dive into the wide world of cable colors, what they mean, and what purposes they serve.

Cable Color Standards 101

First and foremost when it comes to cable color standards, one must realize that while there are institutions like the IEEE helping to provide some standardization, there isn't yet a universally-accepted standard or even requirement in most industries. The color scheme used in one industry can be totally different from what's used in another and can vary significantly depending on exactly when the system was put in place.

Remember the iPhone and the first true smartphone didn't make its appearance until 2007, with that came a huge push for new telecommunications infrastructure to support it. So, depending on the timeframe when the cables are installed in their given systems, their color standards will pretty much cover the full spectrum.

Adding to the lack of standardization in cable colors is the variance from one country to another. With today's global logistics, a company in the U.S. may be sourcing their cables from several different foreign countries that all use different color schemes. With the guidance issued by the IEEE, the Telecommunications Industry Association (TIA), and other industry requirements, such as those for the DOD, standardization is possible but may be a long time coming. However, next we'll see how different cable colors can serve specific purposes in different applications.

What Do Different Colored Ethernet Cables Mean?

Ethernet cables are a very common type of cable used in computer networking. They are used both in residential and commercial applications when a wired network is desired for data sharing and access to the internet. Most often an internet router uses ethernet cables in order to connect to a cable modem and will come with the kit your cable company sends you when you first sign up for services.

However, if you've ever had more than one cable company or even have had one service for a number of years, you know that the ethernet cable color can vary. So, what do the different colors mean for ethernet cables? Are different colors faster than others? To find out, we'll take a closer look at color coding specifically for ethernet cables.

• What Color is an Ethernet Cable?

Like all cables, ethernet cables can come in several different colors. One color isn't "better" or "faster" than another cable, but the colors can help denote the intended application. The most common colors seen with ethernet cables are grey, blue, yellow, orange, and white. If the ethernet cable is destined to be outside, it will often be black and waterproof to help it survive longer in the elements.

• Ethernet Cable Colors Meaning

As we've seen, the meaning of the color of an ethernet cable can vary depending on the where, who, and why of the intended environment. For example, with the Department of Defense (DoD), the government uses different colors of ethernet cords in order to assign a given level of classification for the data being transmitted within the cable e.g. yellow for top secret, red for mid-level, and blue generally for unclassified data.

• Color Code for Ethernet Wires

Again, while there is no direct industry standard for one color over another, there are a few consistencies worth mentioning:

• Gray Ethernet: Ethernet cables that are grey are often representative of a "standard" ethernet connection such as is found in residential and commercial networks.
• Green Ethernet: Green ethernet cables can be used to classify a crossover connection, which are used to connect different computers and/or devices directly together.
• Yellow Ethernet: Yellow ethernet cables are generally used for what's known as "power over internet" (POE) connections. Interestingly, this standard was developed by the IEEE in 2009 to help classify these cords which deliver a 30W current at the level of the port when used with an ethernet twisted cable pair.
• Blue Ethernet: blue ethernet cables are usually used for terminal server connection. A terminal server makes connections to multiple systems to a LAN network possible without having to use a modem or other network interface.

The TIA is accredited by the American National Standards Institute (ANSI) to create and maintain industry standards, including those for color-coding used in cable manufacturing. While these are some of the closest to standards that exist today, most of the TIA's wiring color management schema is still viewed as a recommendation rather than a requirement. Until universal adoption takes place, there will most likely be many different colors used in ethernet cable colors.

Patch Cable Color Standards

As we've come to expect, patch cable color standards may be published by ANSI/TIA but within these recommendations, there has yet to be universal adoption. 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.

The standard colors used with patch cord jackets by the University of Wisconsin include:

• Grey – used for standard ethernet connections
• Green – used for crossover ethernet connections
• Yellow – used for POE connections
• Orange – used for analog non-ethernet connections
• Purple – used for digital non-ethernet connections
• Blue – used for terminal server connections
• Red – used for IP cameras
• Black – used as a general color
• Pink – used as an additional color option
• White – used as an additional color option

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.

Cat6 Cable Color Standards

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. While a Cat6 cable is a twisted pair network cable that's used for ethernet networks, it is also backwards-compatible with other Categories like Cat5 and Cat5e. However, once again we see that industry standards that are used across the board are hard to come by.

Some of the more common color standards for Cat6 cable include:

• Blue – denotes network connectivity
• Yellow – generally used for wired security cameras
• White – also used for wired security cameras
• Grey – used as an interconnection, also known as "jumpers"
• Black – generally used for equipment, peripherals, and/or workstations in a network
• Red – commonly used with VoIP phone systems or other emergency communications systems.

Network Cable Color Chart

If you've spent anytime looking for network cable color charts online, you may have been frustrated at the lack of continuity with different schemes. As we've hit on, the color standards vary widely, but the ANSI/TIA did help this endeavor with their lengthy standard – Administration Standard for the Telecommunications Infrastructure of Commercial Buildings or ANSI/TIA/EIA-606-A.

While the standard goes into tremendous detail for labeling and ease of identification, an actual color chart is hard to come by. Scouring the web, we were able to find a third-party site that published their version of the ANSI/TIA/EIA-606-A standards.

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:

A Final Look: Cat5e Blue vs. Grey

While the topic of many different internet forums, the difference between Cat5e blue and grey is the same as with the other cable colors we've looked at. The deciding factor here is only as far as the design engineer choosing a given color. This is highly subjective and depends on the many factors we've already discussed such as when the Cat5e cable was manufactured, where it was manufactured, and the industry it was manufactured for.

Getting a Custom Cable Assembly Color-Coded Correctly

At Meridian, we custom create more than 70 percent of the products we produce. That means each custom cable is made to the exact specs of the client, to work as intended within whatever electrical system the assembly is destined for. One of the keys to our success here is in our ability to create a unit that is easy to integrate into the client's existing systems. With decades of experience and some of the very best capabilities within custom cable manufacturing, we can design a color scheme that makes sense and that can be seamlessly integrated.
