Ethernet connections - various types including 5, 5e, 6, 6a, 7, and 8...
I've been away from networking games for a while. My internet will soon upgrade to fiber with speeds up to 1 gb, and I'll have dedicated lines for work equipment. I'm looking into different Ethernet cable options (all lengths under 50 feet). I need to understand what the various versions mean and what features are important for running cables in ceilings. Since I'll be using two cables to the same spot, I want to know how interference might affect performance. Please help me grasp the latest Ethernet cable types so I can choose the best ones for my setup and ensure optimal speed with the new internet connection. Thanks!
Typically: Cat5 offers 100Mbit speeds, while Cat5e and Cat6 provide up to 1000Mbit (1Gbit). Cat6A+ reaches 10Gbit. These are official standards. For shorter distances, good cables work well—sometimes you can achieve 1Gbit over Cat5e even without close proximity to other wires. Cat6 is a solid option for most users, but if you plan to lay cables underground, Cat6A or Cat7 could be more suitable for future-proofing.
5e works well with Gigabit 6 which offers 10 Gigabit at 55 meters. Beyond that, 6a delivers 10 Gigabit. These options suit your needs better than the others. 5 is a bit slow for your setup, and 7 and 8 are too costly for home use. If you're concerned about interference, many shielded 6a cables perform better than standard 6 or 5e. I suggest choosing 5e or 6, since 6a is more than necessary.
@GodSeph its a little out of data, Cat5E can do 2.5GB Cat 6 can do ether 2.5 or 5gb. I'll note for 50m runs cat 6 can do 10gb.
Cat5e supports up to 1Gbps or 2.5Gbps, while Cat6 offers 1Gbps, 2.5Gbps, and up to 100 meters at 5Gbps. Up to 55 meters at around 10Gbps is possible with some limitations on cable bundles—typically a bundle of 10 cables in parallel can reach about 55 meters. Cat6a extends this to 10Gbps over 100 meters, provided the connectors are quality-grade. For short distances and factory-made patch cords, you can achieve high speeds without issues. A 1-meter Cat5e patch cord might even deliver 10Gbps reliably, though it's not ideal. In short, invest in genuine Cat6 or Cat6a cables for best performance.
The data seems limited. It appears to be a general overview rather than specific details. There are many factors affecting speed, such as cable length and signal strength, but it’s more about broad guidance than precise numbers. I suspect people often overlook upgrading to stronger cables instead of just boosting speeds. According to Cisco, 5E can support 5G—see their documentation for more. It’s surprising someone would still use 5E for such heavy data transfer.
It centers around similar setups. You deploy a laptop with a built-in 2.5 gbps Ethernet card into an office, connecting it via a 3m Cat6a cable from the desk to a wall outlet. The walls host Cat5e cables extending all the way to the server room. Building managers might resist replacing the existing Cat5e connections, making a switch to Cat6 or Cat6a impractical. For future needs, consider upgrading the server room switch to support higher speeds like 2.5/5/10 Gbps as bandwidth demands grow.
