There was a question that came up not too long ago from someone browsing our website. They noticed that we commonly changed the terms in which we refer to our cables. Most notably is the way we mention Ethernet and Networking cable. In reality there really isn't any difference between the two terms. They can be both interchangeable when referring to our cables. The thing is though they were wondering what is a LAN cable and is there any difference between that and an ethernet cable? In this article we will break down this term for a better understanding on ethernet terminology.

What Is LAN?

To begin this article lets first start with what exactly is a LAN? A LAN stands for local area network and it is a computer network that interconnects computers in a certain area such as homes, universities, offices, commercial buildings, labs and just about any place with a range of computers in a close vicinity. What about over large areas of land, say large corporations and governments? These are called wide area networks.

The beginning of a Local Area Network (LAN) began in the 1970's with the increase in the need for high speed interconnections of computers in universities and laboratories. With the introduction of ethernet by Xerox in 1973-1974 LAN would soon be off to the races. The first introduction of LAN is a major use case came with the install of it in 1977 at the Chase Bank in New York City.

Now that you've got a little bit of an intro and background to LAN let's dive into how does LAN actually work?

What Products Are In A LAN?

Whether you're in your home or business you're probably going to be apart of some sort of LAN. The simplest way of setting up a Local Area Network (LAN) is to use an ethernet cable. But what about a LAN cable? This is where the customers question comes in to play. A LAN cable refers to the same thing as an ethernet or networking cables. So when shopping for a LAN cable and you come across an ethernet or networking cable you will be fine. So in definition a LAN cable is cable that connects to computers, switches and then from the switch to a router, modem or dsl which powers your internet. These devices when connected together with a LAN, ethernet or networking cable form a LAN (Local Area Network).

What Are The Cables Used For LAN?

With LAN being a connection of multiple computers and networking hardware there are various cables that be used. This includes:

Each of these cables have different designs and functions which power an ethernet connection. To touch on these briefly you'll mostly be using coax cable for connection from your ISP to your modem. This cables helps power that connection which give your network internet access. Coax cables are usually designed with shielding inside them to perform in areas with EMI and higher frequencies.

Twisted pair copper cable is your most common cables used to connect your computers, routers, switches, printers, gaming systems, PoE devices, IP cameras and much more. They come in many different categories such as Cat5e, Cat6, Cat6e, Cat6A, Cat7A and Cat8. Each of these cables have a different performance rating. LAN cables also come in unshielded and shielded versions. Shielded LAN cables are for areas with EMI / signal interference. Unshielded LAN cables are going to be installed in your homes and business when no EMI is present.

Fiber cable (fiber optic cable) is a type of cable which is made of optical fibers to carry light. This cable can carry signals over long distances and is another very popular solution for business use.


Here's an example of a twisted pair copper LAN cable:

Can Wireless Technology Be A LAN?

When you think of wireless you think of a connection that is totally free of any cables or other hardware. You might be surprised to know but wireless technology can actually be considered a Local Area Network. The most popular type of wireless technology we use in businesses and homes is WiFi. You can think of a LAN as a way to connect multiple computers together and that is possible over WiFi. WiFi has become popular among many because of its ease of use. It's quick to set up and relatively free of any maintenance. We do though recommend to hard-wire any connection you can for a more reliable network.

LAN's have become a part of our daily lives in many different ways. Whether playing games on your computer to designing graphics on your computer at work it's most likely that you are apart of a LAN. The most common way a LAN is set up is actually with a LAN cable which can hook up to your computer to the switch to then a router or modem. This then created a small community of hardware and cables which we can describe as a LAN. Even though this is a Local Area Network in its simplest form LAN's can get pretty complex. It's even possible that a LAN can connect with another LAN by something called a leased line. Another common way is via VPN (Virtual Private Network). Depending on the overall scope and size of the LAN it could be classified as a MAN (Metropolitan area network) or a WAN (Wide area network.

We hope you found this article helpful on what is a LAN cable and LAN.

To recap:

  • LAN Cable connects to computers and hardware to form a LAN
  • LAN is a Local Area Network of devices and which help connect the network
  • LAN's can be huge in size ( MAN or WAN)
  • Take a look at your setup in your home and see what's part of your LAN
