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.
In most cases, the length of the Ethernet cable will have no effect on the speed (bandwidth and throughput) and I say that because there are very rare cases when people use Ethernet cables longer than 300 feet.
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).
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.
An Ethernet channel is the complete end-to-end connection of a cable run from a router/switch to something you use like a computer. Of course, there are variations on this theme, but suffice it to say that from powered-device to powered-device the maximum ethernet cable length is 328 feet.
Ethernet cable can have a length that is too long. The maximum cable length for copper twisted pair cables is going to be up to 328 feet (100 meters). Anything beyond this and you run the risk of your signal strength deteriorating.
Cat5 cables can carry data, telephone and video signals and have a maximum recommended length of 328 feet (100 meters).
Another disadvantage is the compatibility. Cat 6 cables are not compatible with some older network devices and ports, which means you might need to use adapters or converters to connect them.
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.
You probably don't need Cat7.
Cat7 cables are not a common standard, nor one you need to concern yourself with. If you need the kind of performance Cat7 offers, Cat6A is perfectly up to the task. It's a widely supported cable standard and has all of the benefits of Cat7 without the drawbacks.
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.
Category 8 has a maximum Permanent Link Length of 24m (78') and a maximum Channel length of 30m (100') when supporting 25Gbps and 40Gbps speeds. Category 8 cabling can support data speeds of 10Gbps and lower at a full 100m (328') Channel configuration.
Standards for cable distance recommend that Cat5, Cat5e, Cat6 and Cat6a cables have a maximum cable segment run length of 100 meters or 328 feet. The cable distance specifications are part of the Telecommunications Industry Association (TIA) and Electronic Industries Alliance (EIA) standards.
What is the Maximum Ethernet Cable Length? The popular CAT5e, 6, and 6a cables share a maximum length of 328 feet or 100 meters. That means you shouldn't use more than 328 feet of cable to connect any two powered devices, such as a network switch and a computer.
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).
Due to the rise in CAT6 Ethernet cables, however, they have quickly become obsolete due to their more limited cross-compatibility features. Testing your cables is a vital component of maintaining a productive system that works with you, rather than against you.
Length: Round Cat6 Is Better For Long Distance
It can offset the interference superimposed on it by the outside environment. Therefore, the round wire can be as long as 100 meters, while the flat wire is generally just a short jumper, the longest is about 2 meters.
It could be a virus if you've ruled out software or hardware issues. Viruses and malware affect your computer in many ways, one of them slowing down your Internet speeds. These effects include making your ethernet slower than Wi-Fi. Use your virus scan software or Malware Bytes to see if it's a virus.
Although Cat5e does support Gigabit Ethernet (1000Mbps) over short distances it's a good idea to use Cat6 instead as this is designed to carry more data and you're less likely to get any issues with it.
An Ethernet connection is generally faster than a WiFi connection and provides greater reliability and security.
Splitting an Ethernet signal doesn't split the connection's speed; rather, it opens up a separate channel to another device. There are some cases where the speed may be hindered by certain factors, as you'll soon read, but most of the time, you will have the same speed you would normally have with a single connection.
A CAT 8 cable, for example, is the fastest you can get right now, while a CAT 5 cable is the slowest. An Ethernet cable should also have shielding. The protective layer blocks data-slowing interference by suppressing electromagnetic interference (EMI) and crosstalk which can lower a cable's overall performance.
By using network extender or Ethernet repeater you will be able to extend the network connection beyond 100M. However, the network extender requires power like any other electronic devices. The power outlet has to be placed every 100 meters in order to supply the extender.
