Understanding How Ethernet Cable Length Affects Signal Integrity and Application Limits
When you are buying an Ethernet cable, there are several factors that you must consider. For example, you must know about the best Ethernet cables available on the market and what length they come in. Selecting the right cable based on the internet speed and your usage needs is also an efficient decision that you can make.
Keep in mind that all of these buying decisions can have an impact on the efficiency of your network. The last thing you want to do is have a network with low internet speeds.
The most common question that most people ask is whether the length of the Ethernet cable affects the speed of the network. In this blog, we will answer this question by informing you about the process of data transfer.
The Process of Data Transfer Through Ethernet Cable
Ethernet cables are made up of copper wires that are twisted together inside the cable. When given an electric signal, these wires send electric pulses from one end of the cable to another.
When the signals move from the sending end to the receiving end in the form of electric pulses, they are translated back into the original data sent by the computer.
Speed of Data Transfer by the Ethernet Cable
Ethernet cables transfer data really fast and efficiently. As mentioned earlier, data transfers from one end of the cable to the other in the form of an electric pulse or electric current. This current travels through the copper wires about 64% faster than the speed of light.
It means that the data is transferred through the Ethernet cable at a speed of about 192 kilometers per second (km/s).
Length of the Ethernet Cable and Speed of Internet
Stable Ethernet speed is essential for a highly functional LAN network. It means that whether the Ethernet cable is long or small, the essential thing you need to understand is the speed of the cable.
Keep in mind that the long Ethernet cable does not reduce the speed of data transfer. The reason is that the cable deals with data transmission at a longer length. If you are running cable at the designated length, the speed of the internet will not reduce.
For example, if you have a Cat6 cable, it will allow you to transfer the data at a maximum speed of 1 GBps for 100 meters. It shows that 100 meters is the designated limit for the cable. Similarly, if you run Cat6 cable at a longer length, it will result in a slower speed.
If you are worried because of the slow internet speed, find the best tips for troubleshooting.
Other Factors that might Affect the Speed of Ethernet Cable
Other than the length of the Ethernet cable, there are some other factors that can have an impact on the speed of the network. Let us take a look at these conditions one by one.
Extreme Environmental Conditions
If you are installing the Ethernet in an extreme condition, like an extremely hot or extremely cold temperature, the speed of data transfer might reduce. The reason for this can be the reaction of the conductor element in the wire.
Design of the Cable
Cable design can have a significant impact on the speed of the internet. Shielded cables are immune to electromagnetic interference. It is the reason why you must consider shielding your cables, as it will prevent various resistances from disrupting the signal flow.
To answer your question, does the Ethernet cable’s length have an impact on the speed of the network? Yes, the speed of data transfer stays constant if you are running the data on the specified length of the cable. Similarly, running the network on the cable longer than the recommended length will reduce the speed of the data.
