what do different colors of ethernet cable mean?

Ethernet cables are very common cable types in computer networking. are available for residential and commercial applications when wired networks are required for data sharing and access Internet. Internet routers usually use Ethernet cables to connect to cable modems, and cable companies will provide the service with the kit you provide when you register for the first time.

However, if you have multiple cable companies and even have many years of service, you will know that the color of Ethernet cables will be different. so what does different color mean for ethernet cable? are different colors faster than other colors? To find out, we will carefully study the color coding specially used for Ethernet cables.

● What colour is the Ethernet cable?

like all cables, ethernet cables can have several different colors. one color is not “better” or “faster” than another cable, but the color can help indicate the intended application. The most common colors on Ethernet cables are gray, blue, yellow, orange and white. If the Ethernet cable is destined to be outside, it will usually be black and waterproof to help it survive longer in the assembly.

● Color implications of Ethernet cables.

As we can see, the meaning of Ethernet cable color may vary according to the location, location and cause of the target environment. For example, in the Ministry of Defense (DoD), the government uses Ethernet cables of different colors in order to assign a given classification level to the data transmitted in the cable. For example, yellow indicates the highest secret, red indicates intermediate, and blue usually indicates unclassified data.

● Ethernet color code.

Similarly, while there is no direct industry standard for one color relative to another, there is some consistency that is worth mentioning:

● Grey Ethernet: Gray Ethernet cables usually represent “standard” Ethernet connections, for example in residential and commercial networks.

● Green Ethernet: Green Ethernet cables can be used to classify cross-connections for connecting different computers and/or devices directly together.

● Yellow Ethernet: Yellow Ethernet cables are commonly used for so-called “Internet power “(POE) connections. interestingly, the standard was developed by IEEE in 2009 to classify these soft wires that can provide 30 W of current at the port level when used with ethernet twisted pair cables.

● Blue Ethernet: Blue Ethernet cables are commonly used for terminal server connections. A terminal server can connect multiple systems to a LAN network without using a modem or other network interface.

TIA has been approved by the national standards association of america (ANSI) to create and maintain industry standards, including color coding standards used in cable manufacturing. Although these are some of the closest standards of the day, most of TIA wiring color management schemes are still considered recommendations rather than requirements. Before universal adoption, Ethernet cable colors are likely to use many different colors.

● Jumper color standard

As we expected, the jumper color standard may be released by ANSI /TIA, but in these suggestions, it has not been universally adopted. The University of Wisconsin Network Services Department, using the jumper color standard, led the example by helping to define the colors to be used for each cable system on campus.

● The standard colors used in the University of Wisconsin jumper jackets include:

* Grey for standard Ethernet connection

* Green – for cross Ethernet connection

* yellow for POE connection

* Orange – used to simulate non- Ethernet connections

* Purple – for digital non- Ethernet connection

* Blue – for terminal server connection

* red – for IP cameras

* Black – used in general colors

* Pink – For other color options

* White – for other color options

Depending on the client and application, the jumper color may vary. But the key is simple – consistency. For any new system, keeping a consistent color scheme can help save time and money for implementation and maintenance and avoid a lot of trouble in the future.
