How Long Does Ethernet Cable Last?
An Ethernet cable helps your computer talk to other computers in the network.
Depending on the cable type and quality, it can last for a long time, usually between 5 and 10 years.
But sometimes, your ethernet cable can break sooner or last longer. It all depends on how you use it and take care of it.
Factors Affecting Ethernet Cable Lifespan
Quality of Ethernet cables:
The first thing that influences how long an Ethernet cable lasts is how good the cable is.
Some cables are better than others, and they can last longer. They are made with stronger materials and put together more carefully, and they don’t get damaged easily over time.
The type of jacket in the ethernet cable
Plenum-rated
A “Plenum-rated” jacket is very good at resisting fire and has a low smoke-emitting characteristic. This feature helps the cable last longer than other cables.
Plenum-rated Ethernet cables may have a higher initial cost, but they are worth it because they are safer and last longer.
They are usually used in schools, offices, or malls that enforce safety regulations and standards. Some Cat6 cables feature this jacket type.
Riser-rated jackets
A riser-rated Ethernet cable is not as good as a Plenum-rated but is still very good.
The material in Riser-rated jackets also inhibits the spread of fire. Riser-rated Ethernet cables last a long time and don’t break easily.
PVC
A PVC jacket is not as good as a Plenum-rated or Riser-rated one.
One way to know your Ethernet cable has a PVC jacket is to check its flexibility and resistance.
PVC jackets are flexible and easy to bend but not very fire or heat-resistant.
But PVC still works well enough for some things. PVC network cables are cheap and can easily be in spaces needing an ethernet connection.
You’d find this jacket material in many Cat5 cables or Cat5e cables.
The type of conductor in the ethernet cable
Bare copper conductor
Bare copper wire is a special cable conductor in some ethernet cables.
This wire is made of pure copper, a very good metal for carrying electricity and data.
Copper transmits electrical signals faster than most metals, so data can travel quickly and clearly over copper cable.
Another good thing about copper wire is that it does not break easily. This means the wire is durable for a long time, and the Ethernet cable can last longer.
Copper-Clad Aluminum (CCA)
A CCA wire is made of two metals: aluminum in the middle and copper on the outside.
Ethernet cables with CCA wires are not as good as those with pure copper wires.
One big problem with CCA wires is that they can harden and crack, especially when they are very hot or very cold.
This means that the best Ethernet cable is one with a Plenum-rated jacket and pure copper internal wires.
Usage frequency
How often you use an Ethernet cable can affect its lifespan. The more you use an Ethernet cable, the more it can wear out or break.
Network cables that you move around a lot, bend, or twist are more likely to get worn out or broken.
After a while, these movements can make the wires or connectors inside the cable come loose or break.
Environmental conditions
The weather and the environment can affect the materials that make up the cable.
Too much heat can make the cable jacket soft or melt. This makes the cable weak and easy to damage.
Too cold can make the cable jacket hard and easy to crack or break.
If you use Ethernet cables outside, I recommend you protect them from bad weather and the environment. This involves using pipes to protect them further.
Signs of an Ethernet Cable Wearing Out
Intermittent connectivity
One way to tell if your cable is worn out is if your network connection continues intermittently.
When the wires inside the cable break, it can cause Intermittent connectivity.
If your network connection is not as speedy or snappy as before, it could be a clue that your Ethernet cable is worn out. In this case, you need a new one.
Slow network speeds
Another way to tell if your cable is worn out is if your network speed is slow.
If your device using an Ethernet cable is slow but other network devices are not, the problem could be the cable.
When your Gigabit Ethernet cable is worn out, the data signals can’t move as fast, and it takes more time for the information to get where it needs to go.
In this case, try using a new cable. A new cable can help speed the data transfer and smooth the connection.
Physical damage
It’s important to check your cables regularly for signs of damage, such as cuts, fraying, or other visible problems.
Constantly checking your cables for damage allows you to act before the problem worsens.
Connector wear
The connectors on a Gigabit Ethernet cable are essential for making a good and reliable connection between devices.
RJ-45 Connectors have small metal pins that touch the holes in your devices.
When connectors wear out or break, the metal pins may not stay in place, making the connection between your devices and the network intermittent.
A broken connector can also lead to signal loss. Always check the connectors on your ethernet cable for possible damage.
How to test if an ethernet cable is working correctly or not
Checking Ethernet cables is vital to make sure that they work well.
A bad cable can lead to a slow, intermittent, or no connection. By testing the wires, you may discover plausible connection issues and fix them to keep a good working network connection.
Using a Cable Tester
A cable tester is a tool that helps you check how good your Ethernet cables are and find any problems.
It gives you a fast and easy way to see how well all eight connectors on an RJ-45 cable work.
Process of Using a Cable Tester
Plug one end of the Ethernet cable into the hole on the cable tester that matches it.
Plug the other end of the Ethernet cable into the other hole on the tester that matches it.
Turn on the cable tester.
The tester will check the cable and find any problems. It will show you the results on a screen or with lights.
Ping Test
A ping test helps determine whether your network and Ethernet cables work well.
It sends a small amount of information from one device to another and counts how long it takes for the information to travel there and back.
How to perform a ping test
Open the Command Prompt on your computer. You can do this by typing “cmd” in the search bar on Windows.
Type “ping” followed by a space, then the IP address or website you want to test, and press Enter. For example, “ping 127.0.0.1”.
Wait for the test to finish.
The test will show you how long the information takes to go and return.
If the ping test works well without delays or problems, the Ethernet cable sends data effectively.
Maintenance Tips to Prolong Ethernet Cable Lifespan
Regular Cleaning: Occasionally, you should clean your Ethernet cables to get rid of dust or dirt. You can use a damp cloth or a gentle cleaner (but not too wet) to carefully wipe the cables. This helps keep them in good shape and stops any buildup that can destroy the jacket or connectors.
Avoiding Sharp Bends: Ethernet cables should be handled carefully to avoid sharp bends or twists. These can break the wires inside the cable and affect their ability to send signals effectively. Remember to route and position the cable with gentle curves and avoid tightly wrapping or bending it too much.
Checking Connectors: Regularly check the connectors on your Ethernet cable for any problems. Look for bent pins, loose connections, or visible wear. If you see any issues, it’s crucial to fix them quickly. Broken connectors can lead to a bad connection, so changing or fixing them when needed is very important.
Surge Protectors: Using surge protectors is an intelligent way to protect your Ethernet cables from power changes or electric shocks. These devices, including the wires, help stop sudden voltage jumps from damaging your equipment. Connecting your cables through a surge protector adds an extra layer of protection and can make them last longer.
Protecting Cables from Rodents: To prevent damage from rodents or pests, properly managing your cables is essential. Ensure they are neatly organized and secured, minimizing exposed or dangling sections. You can use cable management solutions like cable ties or deterrents to discourage pests from approaching the cables, helping to keep them safe.
