Two or more computers can be linked together in a wired network using Ethernet cables. A wide range of cables that have already been manufactured in various categories and sizes are available in both physical stores and online retailers.
However, some of our users prefer to create their own network cables from scratch in order to meet their needs and, occasionally, save money. To make everything work properly, they only need an Ethernet cable, RJ45 connectors, a crimper, and a color scheme. But how to splice an ethernet cable?
A straightforward RJ45 coupler can be used to join two Ethernet cables together. If you find that you need more than one of these couplers, you should think about buying a longer cable or cutting your own ethernet cable to length. Using too many of these couplers can start to degrade the signal.

Things To Consider Before Splicing An Ethernet Cable
Even though their components, such as the RJ45 connector and the cable itself, appear to be the same, network cables are not all the same. Those who construct their own Ethernet network cables are aware of the many characteristics that set them apart. Since the maximum speed, a cable is capable of reaching is based on its category, this is one factor that determines the cable’s function. This table would list the different types of Ethernet cables that are currently the most popular.
Additionally, they will have different amounts of shielding depending on the category they fall under, which can shield you from interference and noise. Nowadays, the ideal Ethernet network cable should at least have category 6, whether you intend to make one or purchase one. On the other hand, if the price does not increase significantly and you are considering the future, category 7 might be of interest to you because more and more routers and network cards are available that support Multigigabit connectivity and even 10GBASE-T.
The category to which a network cable belongs should also be known before splicing. They are typically screen-printed on the cable itself, and they are simple to identify. An illustration of a Category 5E network cable would be this.
This is a crucial consideration because if a network cable is spliced with a cable of a lower category, the speed of the network connection may suffer. Therefore, it is wise to learn what category both cables fall under before you begin.
How To Splice An Ethernet Cable?
Currently, there are several tools and devices that we can use to “splice” an Ethernet network cable without losing signal or performance, we must remember that it is not recommended to “splice” the different wires within a network cable, as we have explained previously. If you want to “splice” several segments It is best to purchase the following adapters and devices when purchasing Ethernet network cables with their RJ-45 connector.
1. Female-female Adapter: The Cheapest Way To Splice A Cable
The simplest and most efficient way to splice a network cable is by using female-female adapters, which can also be called couplers. Two female RJ-45 plugs that are connected to each other on this device allow us to attach two network cables to each end. It will function as one if done so. Here’s an example of a coupler:
It should be noted that these adapters are completely passive, do not require any power, and have no effect on the connection. Additionally, it should be mentioned that the loss will be minimal if we use a high-quality device. They may also contain a metallic shield that reduces electromagnetic interference and prevents signal loss to provide a more stable network environment.
These couplers are available on Amazon starting at about 5 euros. But on occasion, given the small price difference, it makes more sense to purchase a kit now so you’ll have one on hand later. An example of this type, of good quality and compatible with categories 5, 6, and 7 would be this one from UGREEN:
This is the cheapest way to “splice” a network cable, and the easiest to do, but we have other options as well.
How Many Ethernet Cables Can You Connect Using RJ45 Couplers?
There is no restriction on the number of Ethernet cables you can connect with an RJ45 coupler. There are a few reasons why you shouldn’t get carried away with this idea, though.
You can have an Ethernet cable running virtually undetectable throughout your home with some ingenious hiding and bending. And if you employ enough of these couplers, you might be able to complete the task using only the available ethernet cables.
However, since Ethernet cables are made to transmit connections from one end to the other, adding more and more of these couplers over time may compromise the quality and speed of the connection. Signal interference is more likely to occur when your cable is longer and you use more couplers.
Not to mention that the couplers are essentially inexpensive plastic components that over time might break or come loose. Therefore, the more RJ45 couplers you add to the line, the more potential failure points you’ve created.
2. The Switch: The Best Way To Extend A Network Cable
The quickest and least expensive method of splicing a network cable without loss is a coupler, but it should be noted that there are better options that offer more. In the case of needing to join two network cables, especially if they are quite long, the best option is to use additional network equipment such as a Switch.
This type of device makes it possible to “regenerate” the signal from the cable itself, reaching a much greater distance without loss of signal. It’s important to keep in mind that cables longer than 100 meters are not permitted by the Ethernet standard, but two segments of 100 meters could be connected together without any issues using a standard switch. Their dependence on the power supply is a drawback, but today’s models have energy-saving features, reducing their overall consumption. We have more connection reliability with this kind of gear.
An example of a switch that we could use is the D-Link DGS-105, with it we can perfectly extend two network cables and improve the connection.
Of course, using a switch will allow you to quickly and easily connect various computers that are already connected to the local network by a network cable without the need to purchase additional hardware.
3. Use An Old Router To Splice A Network Cable
An old router that we have kept in a box could be used as another tool to splice a network cable. One of its potential drawbacks is that if it is too old, it won’t be Gigabit Ethernet and we won’t be able to go faster than 100 Mbps. Another thing to consider is that the outdated router might require some configurations, like being placed within the same current network range and receiving a local fixed IP. As a result, since it needs no configuration, the switch mentioned above might be a simpler option to implement.
The benefit of using a retired router is that it is completely free because we already have one in our house, and we can reuse it to extend an Ethernet network cable. The signal will also be regenerated in this kind of device, just like in a switch.

How To Make An Ethernet Cord At Your Wished Length?
Start with one long cable to connect Ethernet cables quickly and affordably. Choose the one that is long enough for your setup from the selection of inexpensive cables available in various lengths.
By the way, there are various varieties of Ethernet cables. Currently, Cat5e is the most popular, but Cat6 is gaining popularity. Despite having different data transfer rates, both of these work exactly the same.
Additionally, most ethernet cables are unshielded, but shielded Ethernet cables provide a little bit more EMI protection. Knowing the distinctions between shielded and unshielded Ethernet cables and which is best for your application is beneficial.
- Measure the cable length. It’s not necessary to take an exact measurement. Leave the cable in place a little while longer; it makes sense. Use the wire cutters to cut it once you have the desired length.
- Use the crimping tool. Use the crimping tool to remove a few inches of the protective outer jacket. The wires should remain visible. Be careful not to damage the delicate wires as you remove the covering.
- Separate the wires. The process of separating the four pairs of wires takes the longest. You’ll have eight distinct wires after you’re done.
- Get the wires ready for crimping. When using Ethernet cables, the wires must be connected in a specific order. The wires on both sides of the cable must be arranged in the same way. For wiring ethernet cables, the majority of people employ the T-568B technique.
The order is Brown/White > Brown > Green/White > Blue > Blue/White > Green > Orange/White > Orange > Green/White > Blue.
Start pressing the wires closer together once they are all in place. Cut off the extra material, leaving about half an inch behind, once they are arranged straight and without any gaps. To ensure a straight cut and avoid an angle, make sure to cut them off. - Put the connector on. Slide the connector carefully over the wires so that the clip portion is facing away from you. In a slot, each wire will fit. Use your crimping tool to press down on the RJ45 coupler when all of the wires are at the edge of the connector.

FAQs
Can You Splice Ethernet Cable?
Yes, two or more sections of Ethernet cable can be spliced to create a longer cable. Ethernet cables are used to connect two or more computers together in a wired network
What Is Cable Splicing?
Cable or wire splicing is the process of connecting the endpoints of two or more cable conductors. Wires of various lengths are connected while retaining their original properties during cable splicing.
Is Wifi Faster Compared To Ethernet?
An Ethernet connection is generally faster than a WiFi connection and provides greater reliability and security.
Is An Ethernet Extender Available?
An Ethernet extender (also called “network extender” or “LAN extender”) is a device used for extending an Ethernet or a network beyond the 100-meter (328-foot) twisted pair wiring limit. Can an Ethernet cable be extended? Yes you can, shop our products here.
Which is better, CAT 5 Or CAT6?
Compared to Cat5/5e cables, Cat6 cables have stricter performance specifications and significantly higher data transfer speeds at greater distances. In addition to having thicker cable conductors and sheaths than Cat5 cables, they are also more tightly wound.
Should Cat5 Cable Be Spliced?
A CAT-5 cable should only be spliced as a temporary fix. Never use a CAT-5 cable splice as a long-term repair for a damaged or cut cable.
The Bottom Line
As you can see, there are several ways to splice a network cable. The easiest and quickest method is to use a female-to-female RJ-45 adapter because it doesn’t require any kind of power source and joins two network cables in a matter of seconds.
The other benefits of using an old router or switch include signal regeneration and the ability to travel farther.
Having said all of that, it’s important to remember that ethernet cables, along with any couplers or switches, do eventually degrade and must be replaced on occasion. Making your own cable will ensure that it is the ideal length, will last a little longer, and will be more suitable for ongoing use.
