Ethernet Cables

Different Colours of Ethernet Cables

Ethernet Cables

Ethernet cables are one of the most important networking hardware that support transfer of data and work of communication. It is used in many areas such as home networking, business networking and VoIP etc. Ethernet cables are also called optical cables as they have similar characteristics with traditional copper cables. Ethernet networking cables use different types of networking protocols and are of high bandwidth. The Ethernet cable has an outer shell made from metal, plastic or fiber glass.


Shielding helps in reducing the interference which can interfere with radio signals. It also makes the transmission faster. There are two kinds of Ethernet cabling namely, full-protected and single-protected. Full-protected cables come with extra measures for power distribution. Single-protected cables do not provide any protection against external environment.


Almost all of us have at least one device connected to the internet today. Some of them are mobile phones, wireless printers, computers and laptops etc. All these devices require networking especially the internet routers and Wi-Fi routers. All these devices are dependent on a wireless router and thus need to have some essential features to enable smooth operation. Networking becomes very important in order to have a successful business or if you want to browse the internet easily your internet browser has to be on and available with a good web connection.


In order to complete these functions, it is important to attach the devices to each other. Thus there are different types of Ethernet cables available in the market for each and every purpose. The two major varieties are straight-through cables and multi-mode fiber optic cables. Let us have a look at both of them.


Straight-through Ethernet cables are the oldest type of Ethernet cables which have a copper shield within the cable jacket. These older cables are used in many places where the distance is not more than 100 meters. They can be used to connect phones, modems, printers etc with computers through Ethernet ports but they are not very popular among consumers due to their slow speed and higher cost.


These Ethernet cables are made from the same material as the original Ethernet cable but the Ethernet components are incorporated in the middle layer. These copper wires are coated inside a plastic tube which has a PoE heatsink embedded in it. PoE stands for Point of Ejection Technology and these heat sinks are required because the current coming from the computer can heat up the copper wires during power plugging and unplugging. The thicker the cable, the higher the temperature will get and the longer the data will be lost before being transmitted over the network. Cat 6 Ethernet cables, which are technically superior are slightly expensive than the older cat 6 variants but have much better transfer speeds and power delivery.


Ethernet Cables can be installed directly to any type of PC or network card without the need of physical connection through cables. However, this option is not applicable when the PC has only one port as it will create a routing delay. A good routing strategy will help avoid this delay however if your network has more than one device then it is recommended that you use a cabled Ethernet link between all the devices. This will allow the PC or devices sharing a single port to have fast data transfer speeds regardless of the physical location of these devices.


There are many different colours and designs of Ethernet cables being used today but the most popular ones are blue, red and black. These three colours are popular because they represent the most common usage scenarios. If your network contains mostly computers then it is likely that you will have a mix of devices and routers so choosing a cable colour may be difficult. If your network consists mostly desktop computers then a purely plain cable may not be ideal as you need to be able to differentiate the cables. If your budget allows then a cable with different colours and designs will look very nice and will help people easily identify which cables belong to which devices.
