Yeah, definitely no "too short" limit for ethernet to work. Not even device to device. The electrical resistance difference between a 1-inch cable and a 10-foot cable is virtually immeasurable. It's not until you get to that 100m mark that the resistance of the wire starts to add up and cause potential issues.
You can extend your ethernet cable via inline couplers. Wire both ends of both cables with RJ45 male connectors, and use inline ethernet couplers with female /female RJ45 connectors. Another option is to wire an RJ45 ethernet port on one end of one of the cables and extend them directly.
Although high-quality cable can support stretches of over 100 meters, you may experience a reduction in transmission speed. So, does the length of Ethernet cables matter? The simple answer is yes, though you will almost certainly never run into problems in most residential applications.
A single run of Ethernet cable is designed to work at a maximum of 328 feet or 100 meters. It's entirely possible to exceed the manufacturer's specification and still maintain network connectivity. However, this greatly increases the chances of connectivity issues, reduced speeds, and lower reliability.
Cat6 cables support 10Gbps for a distance up to 180 ft (55m). If you go beyond this then the speed will drop to 1 Gbps.
Cat 6 Ethernet cables, for example, can operate at up to 10 Gbps at lengths up to 55m (180 feet), but will be limited to just 1 Gbps once you go over that threshold, and continue to do so up to the maximum of 100 meters.
Since you can't exceed the 100-meter limit for a single run of cable, you can place a network switch in the middle to extend the overall reach of the Cat6 Ethenet cable. A network switch is a device that can provide additional ethernet connections to your network.
Ethernet - 100 meters (328 feet)
Cat7 gets advertised for its 100 Gbps speed, but that will only work for distances up to 15 meters (slightly over 49 feet).
CAT 7 Ethernet cables support higher bandwidths and much faster transmission speeds than Cat 6 cables. As a result they are much more expensive than their Cat 6 counterparts, however, if you are looking for better performance, they are worth the extra cost. Cat 7 cables can reach up to 100 Gbps at a range of 15 meters.
While a number of variables determine actual speed of a WiFi connection and an Ethernet connection, Ethernet is almost always faster than WiFi.
To put it simply, the data transmission speed of ethernet network cables remains constant as long as they are run at their specified lengths. However, running cables longer than their recommended lengths reduce the data transmission speeds.
But as the signal moves through copper, it degrades due to resistance. As a result, all Ethernet cables have a maximum distance limit. If you run an Ethernet cable for a distance longer than its limit, you will notice a decrease in the connection speed.
You may have a slow Ethernet connection for the following reasons: The Ethernet cable you're using is faulty or damaged. Ethernet cable is of a lower category and has a lower data transfer cap. Ethernet ports where you are connecting the Ethernet cable are having a problem.
Extending Ethernet cables beyond their range limits is relatively easy when you know the key. You need to add a device at the node between your two runs of cabling. So, if you need to connect two computers that are 200m apart, you'll need a device at the halfway point.
When you run Cat 5/6 UTP the minimum is 3' (90 cm). You cannot (should not) use cables shorter than 3' (90 cm). One cable between a router and a patch panel won't likely exhibit a problem, but multiple will. The specification is clear.
You can even extend the Ethernet cable by using an extender device. It utilizes the DSL technology that enables data transfer. In doing so, it can offer a speed of 10 Mbps over 1450 meters and 50 Mbps at 300 meters. One of the best things about the device is that it is highly durable and is cost-effective.
It's a dead standard that isn't going to see any further adoption and its benefits are easily matched and outweighed by competitor cables, like Cat 6A, or the latest and greatest, Cat8. In the vast majority of cases, if your network is less than 10Gbps then Cat6A cable is going to be all you need.
It is officially recognized by the IEEE and EIA and parts and pieces are standardized across manufacturers. The primary benefit of Cat8 cabling is faster throughput over short distances: 40 Gbps up to 78' and 25 Gbps up to 100'. From 100' to 328', Cat8 provides the same 10Gbps throughput as Cat6A cabling.
Cat8 is the fastest Ethernet cable yet. Its data transfer speed of up to 40 Gbps is four times faster than Cat6a, while its support of bandwidth up to 2 GHz (four times more than standard Cat6a bandwidth) reduces latency for superior signal quality.
Cat 7 Cables:
Cons – They are a bit expensive. They require 40 to 60% more space to contain the cable and different connections. Their testing is trickier and requires modern test equipment. There is no real speed advantage over a good Cat6a system.
In 2002, Cat7 wire cabling standards were ratified, allowing 10 Gigabit Ethernet Cat7 cable diameters of over 100m of copper cabling. Cat7 maximum length, like Cat5e, Cat6, and Cat6A, has a maximum distance of 328 feet (100 meters).
The max length of an Ethernet cable is 300ft. If you need to go past this distance you will need a device to repeat the signal and power. This can be done with a POE injector or a POE switch. A POE injector will be cheaper but can only be used with 1 camera.
Ethernet segments are limited to lengths of 100 meters because stations connected to Ethernet share a communication medium. If two stations send messages at the same time, both signals distort and become unreadable.
While standard Ethernet cables can measure up to 100 meters and can handle connectivity across this distance, you will need more than this if you wish to go beyond the 100 meter-benchmark. Extenders and boosters will make sure your connection stays strong, even as you install more cable to meet your needs.
