Extending Ethernet Cables (Complete Guide)

Extending Ethernet Cables (Complete Guide)

Sometimes, it can be difficult to find a long enough network cable to reach the back of your computer. Luckily, there is a simple solution for extending ethernet cables to the required connection. You can easily convert a short ethernet cable to a much longer cable and use it to route the way you need it to go. When you circulate the network in your home or office building, inaccuracy in cable measurement for estimating distance can result in the need for more cable to cover the distance.

Thanks to the network couplers like Inline Couplers, Network Switch, Fiber Media Converters, Ethernet Repeaters, and Wireless Ethernet Extenders, we can make a long-range network without compromising the speed and performance. It s not an odd activity, we’ve all used extension cords and power strips for some point to lengthen the cords. The procedure is similar for ethernet cable extensions, but with a little more care and technique, you can ensure safety and extend enough ethernet cable to reach your devices without signal loss.

Extending Ethernet Cables

The use of ethernet cables is significant in local area networks (LAN), corporate firm’s data backups, servers connections, office networking, data centers, and WANs connections at organizations. The thing is ethernets are widespread for stable and reliable wired communications and mature for connecting workstations, security monitoring stations, and industrial environments to manage piles of data transmissions.

Ethernet cables extension’s are used extensively in local area networks (LAN), corporate data backups, server connections, office networking, data server farming, and WAN connections at organizations. The fact is that Ethernet is widely used for stable and reliable wired communications, and it is mature for connecting workstations, security monitoring stations, and industrial environments to manage massive amounts of data transmissions.

Extending Ethernet Cable

The extending ethernet cables are worthy for internet devices like your router, network LANs interconnecting together for all the working space and it usually comes cheaper than WiFi extenders with very low latency. Besides working ground ethernet joints the gaming setups to servers and other computers on the network for seamless sharing and high-speed internet.

The generations, Cat5 and Cat5E are older and infrequent while newer Cat6A, Cat7A, and Cat8 are solid speed excellent performance ethernet cords for home private networks or private firms’ data transmissions. However, the problem occurs when your cords are short at distance and you want an inexpensive solution that can lengthen the ethernet cables and you don’t know how to extend the ethernet cable.

Situations like that can be fixed in multiple ways. There are Ethernet Switches that play the role of transferring one cable to multiple routes for network devices in a LAN but they aren’t the cheapest compared to Inline Couplers such as RJ45 Couplers, those are affordable to do the work of combining two ends of ethernet cords to make it one long-range cable for up to 100 meters (328 feet) range.

Ethernet Cable Distance Limits (Beyond 100m Length)

Ethernet Cable Distance Limits

Unlike fiber optics networks cables, the ethernet cable certainly has maximum length limits, which can go as long as 328 feet (100 meters) and anything beyond can drop the electrical signals of ethernet cables to break the transmissions, which means the cables couldn’t carry and maintain a signal over vast distances networks.

The newer category 7 and category 8 ethernet wires known as Cat7 and Cat8 twisted copper cables for the modern application for long-range high-speed data transfer such limits range from 10GBps to over 40GBps Ethernet signaling. While Cat5, Cat5E, Cat6 & Cat6A cables are used for relatively less speed but are more affordable in regular working wired network infrastructures.

The maximum length of Cat6 Cable without data loss is 328 feet including patch panels. It is the standard limit that can be extended further with additional devices such as routers and Ethernet extenders. In this article, we will be focusing on extending Cat6, Cat7, and modern very high-speed category cables for suitable networking businesses such can fully utilize the speeds.

The maximum length of ethernet cable from the router to the PC can be 100 meters, which is the maximum length of an ethernet cable tested by the manufacturer to ensure the speed and performance of a network. In terms of the distance between the router and the computer device, it is best to keep it under 50 feet.

How To Extend Ethernet Cable Length?

It can be extremely inconvenient to run out of ethernet cable in the middle of a project. However, how simple is it to extend an ethernet cable? I will assure you’ll look back at some time when you need to understand the different ways to extend ethernet cables. I’ve described personal opinion with facts so that you can consider peoper knowledge about things that matters for ethernet cables at access points, network switches, access points, routers, range extenders, portable modems, game consoles, computers, printers, security cameras, streaming boxes, NAS storage, Android boxes and more.

Things You Need When Extending Ethernet Cables

You should start with the possible fix using a powerline adapter. The powerline adapter uses the electrical wiring within a home to transmit a wireless signal. It’s a great way to extend a network and it’s a better alternative to a wireless adapter. Make sure to have a good WiFi router, however, powerline adapters aren’t the best for transmitting a lot of data in a wide space you can extend a small network with a powerline adapter, but it shouldn’t be the only method of connecting devices.

1. Inline Couplers (RJ45 Couplers)

You can connect two ethernet cables with the help of an RJ45 coupler to extend their length. The RJ45 inline coupler has two female Ethernet ports on both ends and functions as a keystone jack, allowing two cables to be inserted on each side. RJ45 is the standard “Registered Jack 45” connector that is common in ethernet cables and Telecom coupler ISDN / ADSL types for every extending ethernet cable network.

Simply connect one ethernet cable to one side of the coupler and then, on the opposite side, insert the second cable that you carry for an extension. It is a simple solution for any connection with standard range limits. You can extend the length of your ethernet cables for any long-range connections as ethernet couplers are compatible with the most recent category of ethernet, Cat7, Cat6, and Cat5 for extending your runs.

2. Network Switch (LAN Networking Device)

The Network Switch is a device that connects multiple devices via ethernet cables in a LAN network. The use of a switch enables each connected device to communicate with others in a faster communication with pluggable modules. It receives and forwards data to your end devices by switching packets over a single IP with a single router, which is ideal for a large number of users in a WAN.

In usual applications, they are found in network hubs and are essential components of any customized means of a network. They are versatile and can use for extending the ethernet cable. You can also use a switch device to make multiple network connections if you need more ethernet connections. It can easily extend the length of your ethernet cables and not just one but more than two or three cables for all of your end devices.

3. Fiber Media Converters

It is a more expensive solution to extending ethernet cables but offers an undeniable extension of an Ethernet network beyond 100 meters standard distance limits. The use of Ethernet cabling with Fiber Media Converters is extraordinary for any long-range connection that needs more than 328 feet range for coverage. A typical application of ethernet to fiber converters allows UTP copper-based ethernet equipment to be connected over a fiber optic link for faster data transmission over large distances.

For heavy-duty works and NAS, a copper ethernet connection with a fiber media converter provides an extension of connectivity to many other forms like traditional ethernet to ethernet, ethernet to Gigabit connection for 10 Gigabit or more speeds, and ethernet to OpticalFiber for rapid internet connections for professional devices.

4. Ethernet Repeaters

This is another way of breaking the 100 meters copper barrier for ethernet and extending it further for extra long-range range connections. The solution is perfect for extending ethernet cables within a building or campus. Even though ethernet technology limits the maximum length to 328 feet (100 meters) in a connection but the barrier can be broken for larger networks like WANs, Office Building Coverage, NAS networks, CCTV security, Campus Internet, etc.

The ethernet cord extenders like ethernet repeaters are the possible saviors for extending ethernet over 100 meters barriers and are used as core network lines that span long-distance connections. Repeaters connect multiple ethernet segments by repeating the signal to all other segments connected to the repeater. It is that when a network cable exceeds 100 meters, a repeater is required to significantly increase the diameter of your network by running multiple cables to end devices or computers to the network switch.

5. Wireless Ethernet Extenders

Plugging an ethernet cable into a WiFi extender can extend teh range of internet to a house or office. A modern router with basic specs can broadcast a wireless signal within an area of about 70 meters (230 feet) without the assistance of boosters or repeaters. When you add Wireless Ethernet Extenders they can wireless broadcasts signals to more than twice the range of a standard router signals range.

It will average around (260 feet) 140 meters. The solution is expensive and costs more than ethernet couplers or network switches. If you are willing to spend then Wireless Ethernet Extenders are suitable for increasing the ethernet network range at far distance areas in your home, office building, or campus area that requires WiFi coverage.

One thing is certain using the cheapest option for extending the ethernet cables can cause issues to your network and may degrade signals. But the possibility of mistakes is always here when you make terminate the ethernet cables by yourself. So it doesn’t matter what option you choose, the result will vary for safety, precautions, and procedures errors.

The only most affordable option Rj45 inline coupler should do the trick when you are not planning to invest more than a couple of dollars for extending the ethernet cables. However, if you have more connections over a single line then going for LAN Networking Device (Network Switch) or Ethernet Repeaters could make a significant difference over 100 meters length connections.

When you have done everything correctly, the result should be expected and you can reliably use your network for testing your speeds for effects and comparing both to justify the hurdle of cables length. The testing process can be carried out using either the ‘FAST’ speed testing tool or ‘Speedtest by Ookla‘, both are reliable for exquisite results.

Remember: For the initial network, the use of unshielded cables is good for short-range connections while for extended long-range cables the shielded cables improve performance and reliability. It is because unshielded twisted pair (UTP) cables may be adequate for a short run between a computer and router, but shielded (FTP) cables are preferable for longer runs.

Types Of Ethernet Cables: Their Impact On Network When Extending Ethernet Cables

Types of Ethernet Cables and their Impact on Extending Networks

When explaining ethernet cables, they are classified into five types that are commonly used in local area networks LAN, and organizational networks. But despite the types the data transfer speeds, the length is proportional to the speeds and type of the cable.

These are Twisted Pair Cables, Standard Ethernet Crossover Cables, Ethernet Categories Cat5, Cat6, Cat7, and Cat8, – Coaxial Cables as alternatives for Cable Internet and FiberOptic Cables. Although each category of ethernet cable has had significant speed over the last one, the difference in technology makes them a completely new form of cable.

1. Twisted Pair Cables

The use of twisted pair ethernet cables is more vast than any other cable due to the telephone lines. The twisted cables are recognized for both telephone communications and basic ethernet networks. They are low-cost, older, and durable unlike Fiber cables have brittle tendencies to break on a couple of twists.

2. Standard Ethernet Cables

The current standard ethernet cable is Cat6A and it is widely available for all sorts of internet connections at home networks, office buildings, data servers, and NAS. It can support speeds up to 10GB per second (250 MHz) under 100 meters and goes down as 1-Gigabits-per-second for up to 328 feet in length. The best part is that it is less expensive than newer Cat7A and Cat8 cables, which transmit data at a faster speed over a large distance but cost more than triplex.

3. Ethernet Crossover Cables

The purpose of crossover ethernet cables is different than standard ethernet cables. Ethernet crossover cables are used to connect two ethernet client devices directly to each other without the use of a switch or router. The working applications can vary for the situation but are normally purposed for connection between two computers, network storage, routers, and hubs to communicate and send and receive data directly together.

4. Coaxial Cables as Alternatives

Coaxial cables are alternative to ethernet and used for a variety of transmissions such as internet connections, radio frequency signals, cable television, and digital audio and video (S/PDIF) services. However, can convert to an ethernet network backbone for small area networks.

5. FiberOptic Cables

The FiberOptic cables are extraordinary Optical Fiber cables that perform super-speed networking and send data signals in the form of light. they came in two types, Singlemode and Multimode. The transmission performance limits data speed at 10 Gbit/s for distances up to 550 meters, 1 Gbitps for distances up to 1000 meters, and over 2 kilometers distance the speed varies 100 Mbit per second.


A short ethernet cable in a network could be a serious issue to mess up the entire networking system in your home but still, it can be fixed with an Ethernet Coupler device by following the extending ethernet cable guide. Hope my blog will resolve the issue and extend your ethernet cable network to either a normal range of 100 meters that is (328 feet) or further increase the length for distance networking devices with the help of Fiber Media Converters and Ethernet Extenders (PoE repeaters), but those are a bit expensive than the typical Inline RJ45 Coupler or Network Switch.
