How to Buy Ethernet Cables? What to Look For

It is important to select the right Ethernet cable to ensure the best performance is obtained for the best price Cat 5, Cat 5e, Cat 6, Cat 6a, what is the best buy? Buying Ethernet cable is not always as easy as it might seem. There is a huge selection of cables of different types like Cat 5, Cat5e, Cat 6, and Cat 6e, as well as different lengths colors and the like. These are available from a variety of different suppliers.

It is important to buy the right cable for you over-specify it and you will pay too much, under-specify it and the performance will be impaired and the local area network or Ethernet link will not work as well as it might. Selecting the right Ethernet cable will ensure the best performance is achieved for the best possible price. 

How to Buy Ethernet Cables

To ensure the best cables are bought for the system, it is necessary to have a little understanding of what is needed. It is worth taking a little time to assess exactly what is needed and find out the various options of what Ethernet cables are available. Aspects like performance, price, availability, quality and more all affect the decision. Although some are difficult to judge, knowing the facts can help make an informed decision about the best Ethernet cable to buy.

Ethernet Cable Requirements

Local area networks are commonplace these days. Homes with broadband have routers that not only give Wi-Fi, but also have the option of Ethernet typical routers for the small office or home local area networks often have four Ethernet ports, and those for larger offices will typically be dedicated Ethernet routers and Wi-Fi access points will be able to be located as required.

The routers and additional switches will mean that many more Ethernet cables will be needed. When the better Ethernet cables come into their own are when files are transferred between devices for backing up, streaming video, streaming games, and the like. The faster speeds of the more up to date better Ethernet cables can make a real difference.

Although Wi-Fi is advancing and offering much higher levels of performance, so too is Ethernet, and cable offers some distinct advantages in many circumstances.

Wi-Fi can be dependent upon the location, whether there are any obstacles on the way, the distance to the router and much more. Ethernet cables offer a reliable level of performance and are often preferred for many offices, and they can be very useful for home local area networks as well. When thinking about the cable to use, remember that for many connections, it is the Internet connection that is the slowest link. Even fiber broadband will be slower than the average Ethernet cables, so if it is just for Internet surfing only, then a very average Ethernet cable will suffice. 

Ethernet cable performance

There are a number of Ethernet cable categories that can be seen in the market. Cat 5, and Cat 6 are all widely available, with Cat 5 being the oldest standard and the newest and with the highest performance. The different category cables have different levels of performance and as a result, it is important to select a cable that will meet the requirements for the system. Using the table below it is easy to see the comparison between the levels of cable performance for when they are bought.

Often the issues can arise when older cables are used. Most of us will have an accumulation of Ethernet cables that have been acquired over the years. These may be from earlier standards and may affect performance. If the cable has come with a new router, then it is probably one of the newer categories that will be fast.

Compatibility

The only real issue with using an older type cable like the Cat 5 is that it won’t support such fast data transfer speeds. It is possible to plug a Cat 5 cable into a router that has the latest 10G Ethernet interface. The only issue is that the cable will slow the data transfer down. This may or may not be a problem depends upon the type of file transfers. This means that when buying an Ethernet cable, there is a lot of flexibility.

How to Buy Ethernet Cables

Ethernet cable length

Ethernet cables come in a variety of standard lengths. Whilst t is possible to construct your own cables, most people will want to use one of the pre-made cables. Cables are widely available in a variety of lengths: 0.5, 1, 1.5, 2, 5, 10, 20 meters are very common. Maximum lengths of around 75 meters are relatively easy to find. If different lengths are needed, shop around because there is a huge selection available and different stockiest will stock different cable lengths, some with a much greater selection than others.

When determining the length, make sure the cable will be long enough. Typically there needs to be a little slack because cables always seem to need to be longer than the very shortest lengths measured. Allow a little margin, but not so much that there is a lot of cable length to be used up. Obviously, when installing the cable into a house along with another permanent wiring, cable in a reel will be bought and terminated as required to the relevant sockets. Reels of Ethernet cable can be bought in reels up to 500 meters or more.

Cable color

Whilst for many applications, the cable color is not important, in some instances, it can be very useful to be able to select the color. When there are many cables together it can be helpful to have a variety of different colors and this helps track the cables through and make sure the right cable is connected to the right position.

This type of thing can be useful where a large router or switch has many connections, or there is a patch panel of some description. In some instances, an Ethernet cable color code may be devised for cables with different users, or those connected to different branches of the local area network. Cable colors can be put to good use like this. For domestic use on home local area networks, the complexity is much less and color-coding of wires is not normally an issue. Here the color choice may be required to make it stand out less – grey may be a good choice, although there are many more colors.

Suppliers

There are many different suppliers of Ethernet cables. Some may be specialist suppliers and others like Shireen Cables stock a huge number of items as well. For commercial installations, there is normally a requirement to go to a supplier with whom there is an account so that items can be bought and the number of different suppliers a company has is minimized. However, for many applications, it is possible to go to a variety of different suppliers. 

How to Buy Ethernet Cables

Shireen Cable is easy, reliable and its delivery is normally very swift. If quality is an issue, then a reputable make can be chosen from the enormous list of available items. It is always a balance between performance (including reliability), availability and cost. That said the quality of most cables is very good and the performance is dependent upon the selection of the Category type.

Ethernet cable choices summary

The big decision when you want to buy Ethernet cables is making the choice of the best Ethernet cable for your need. Performance benefit over cost. For the domestic purpose, Shireen Cat 5e cable is generally satisfactory for most applications. The Internet connection is normally the main bottleneck and if you are not continually transferring huge files, then using Cat 6 cable is not likely to make much of a difference. In any case, all the Ethernet equipment has to support the higher speeds anyway and any transfer will default to the lowest speed element in any connection.

How to Buy Ethernet Cables

If you want to be sure of getting the best speeds, then Cat 6 and Cat 6a cables are a good bet. They often don’t cost too much more than Cat 5, and for future-proofing then they are a wise option. Also, Cat 5 is now obsolete so it is best not to use it. Cat 7 cables don’t offer a huge advantage over Cat 6a in real terms at the moment.

That said they do offer better shielding and this can help maintain speeds over longer distances. So for cables that are being installed, say, to wire a home, then it can often best to pay the extra to ensure the best speeds and this will future-proof the system for as long as possible. For commercial systems, it is obviously worth paying the extra for the fastest cables possible. Small savings at the expense of performance can cost money over the longer term.
