Cable Ethernet
Cable Ethernet
You're planning to run Ethernet from your router downstairs to your bedroom upstairs. A 5m Ethernet cable seems suitable for a straight path through the floor. Look into Cat 6 or higher for reliable performance, especially if you expect high-speed data use.
Any length of 5 meters isn't important for Cat5 or Cat6 cables.
Cat 7 offers little value for most networks. Most "Cat 7" cables don’t use connectors that comply with the Cat 7 ISO standard (GG45 or TERA). Opt for Cat 6a instead, since you’re more likely to find a cable that truly meets the requirements rather than a marketing version that isn’t recognized by TIA.
Technically, Cat5e and Cat6 can transmit a 1Gbps signal up to 100 meters. Cat6 performs at 10 Gbps over shorter ranges, while Cat6a supports 10Gbps up to 100 meters. In my opinion, using Cat6 is a better choice—it's a more advanced standard, tends to be more affordable than Cat6a, and could handle 10Gbps if required. Avoid using CCA (copper-clad aluminum) cables, as they are usually of lower quality.
