Gigablast Ethernet cable designed for high-speed connectivity.
Gigablast Ethernet cable designed for high-speed connectivity.
Your ISP has completed the installation, and you're currently preparing your setup. Your main system will be wired with about 25 feet of cable, and both your router and motherboard support a 1-gigabit connection. It seems you're considering Cat 8 for the fiber line.
You might think Cat8 is necessary because Cat5e handles gigabit speeds, but it actually supports up to 2.5Gbps, making it more than sufficient for that requirement.
Cat8 targets extremely high data rates over short ranges (up to 36 meters). It's built for datacentre environments, not home setups. Cat 5e works well, or Cat 6/6a offers similar performance at a lower cost while enhancing noise reduction.
