Know all about Ethernet Cables – Types, Working, Purpose, Benefits, and more

Ethernet cable is the wire or the cords that allow you to connect your electronic device, such as a computer, laptop, or tablet, with a shared network. The primary use of Ethernet cable is for the internet. The Ethernet cables are used for connecting two devices to transfer files, data, or access internet connections, and the synonym of Ethernet cable is networking cable. There are mainly two types of Ethernet cables; straight-through cable and crossover cable. Examples of straight-through cables are Cat 5, Cat 5e, Cat 7 network cable, Cat 8, and etc.  

How do Ethernet Cables transfer data?

Inside the Ethernet Cables, there are several numbers of copper or optical fibers are present. On setting up a connection, they use either an electrical signal or light signal in the form of analog or digital signals to complete data transformation. These cables provide three types of connections, Local Area Network (LAN) Ethernet Cables, Metropolitan Area Network (MAN) Ethernet Cables, and Wide Area Network (WAN) Ethernet Cables. The Ethernet LAN cable is widely used in homes, institutes, or offices, while the wan ethernet cable service is provided for a third party, generally internet provider. The length of the Ethernet cables ranges from 0 meters to 100 meters. 

What are the benefits of using Ethernet Cables?

  1. Energy Saving

The newest Ethernet cables, Cat 6 & Cat 7, are designed to consume less energy than a wifi network, thus lowering the energy bill and proving beneficial to the environment. 

  1. Public Security

If we think about another popular means of sharing networks, wifi is the perfect example, but wifi is more prone to hacking and is not entirely safe. If we look at the ethernet cables, then one has to physically plug in the device to access its services and hence more secure. 

  1. Speed

For the maximum frequency range of 5 GHz, the wifi gives the speed of 1300 Mbps, while the ethernet cables provide speed up to 10Gb/s and hence probably the fastest means of data transmission. 

  1. Reliable

Ethernet cables are wired connections and are less vulnerable to interferences like loss of signal etc. Meanwhile, wifi is the wireless connection, and its services can be hindered while in contact with other signs. 

  1. Potential

In wireless connections, there is some time elapse in receiving and sending the signals in between the router and the device while in ethernet cables since the devices are plugged together, so you cannot observe the time elapse; they are very minimal.

What are the applications of Ethernet Cable Networking?

Ethernet cables provide many connections to choose from, so it has it used in different sectors like industries, schools, offices, homes, etc. The use of single-mode or multi-mode ethernet cables depends upon the purpose. 


Ethernet cables’ demand is increasing daily because of their properties like efficiency, great speed, flexibility, security, and more. In recent times it is very convenient to find a networking cable instead of a wireless network.
