Determine the appropriate Ethernet cable type for your home wiring setup.
Determine the appropriate Ethernet cable type for your home wiring setup.
I'm starting the renovation and chose to install hardwired connections. I originally intended cat 6a Ethernet cables, but I prefer not to replace them every few years. Nearby stores sell cat 5e to cat 7a cables at similar prices. Should I opt for cat 6a now or upgrade the wiring to be future-ready with cat 7a? Also, I understand that cat 7 and 7a cables don't use RJ45 connectors.
From ISP I currently get 75Mbit/s, with an upgrade to 500Mbit/s fiber expected in about six months. Internally, I plan to connect a NAS using a 1Gb Ethernet port.
Cat6 is more than sufficient; just ensure you purchase it without CCA cable. CCA stands for Cooper Clad Aluminum, which is unsuitable and should be steered clear of.
It depends on budget and requirements. A 10 Gbps connection isn't realistic for most providers soon. Comcast offers 2 Gbps fiber for about $299 a month plus installation fees up to $1000. You shouldn't base this choice only on current service levels. Consider scenarios where higher speeds might be necessary. Alternatively, you could upgrade your setup with Cat6a and adjust equipment as needed.
Cat5e supports speeds up to 1 Gbps and 2.5 Gbps when paired with compatible Ethernet cards and switches that back the 802.3bz standard. Cat6 works well at 1 Gbps or 10 Gbps over short ranges (under 40-50 meters). If the 802.3bz standard is available, it can reach up to 2.5 Gbps and 5 Gbps with Cat6a, which supports up to 100 meters at those speeds. For higher performance, a quality Cat6a cable is recommended—avoid CCA types (aluminum-clad copper). You can test by scraping the wire; silver shine suggests aluminum presence. These cables are ideal for short-term use, but full copper is better for long-term reliability. If you plan to stay in place for years, consider adding fiber through walls. LC-LC fiber costs around $1 per meter on Amazon from several brands. The thin strands can be run alongside Ethernet cables in some areas. Microtik offers affordable switches with multiple 10 Gbps ports and gigabit ports at budget prices. You’d need two 10 Gbps transceivers, plus a few switches, for setups like the ones listed—prices start around $150 each. Cheaper options exist on eBay, and budget switches with SFP+ ports let you connect fiber between rooms and add more gigabit ports as needed.
So, you're thinking about cable placement inside walls. Cat 6a is suitable for walls, not CAA. The main switch should include at least one SFP+ port for fiber. If you plan to stay longer, consider adding LC-LC fiber alongside cat 6a. For distances over 100 meters, use fiber from main switch to secondary switch and copper to those rooms. A NAS should connect to the main switch. For Ethernet outlets, place a Wireless AP in rooms needing WiFi. Regarding extra Ethernet ports, it's better to install a switch in each room rather than running more cables from the main switch.
The device you receive from your internet service provider should function as both a router and a modem. It typically includes at least one 1 Gbps Ethernet connection, and likely has four or more ports on the rear panel. For homes with limited space, linking each room to a separate port makes sense. Still, adding either a network switch or a dedicated router would be practical—especially if your ISP allows it. In that case, the modem can act like a standard fiber-optic connection, handling authentication and static IP assignment while your router manages routing and security features. You don’t need a switch with an SFP+ interface; simply note that SFP+ ports support up to 10 Gbps and are common in modern networking gear. Upgrades like QSFP+ or even 40 Gbps switches are possible, but they’re usually reserved for large data centers. For now, investing in a few meters of fiber and a 10 Gbps switch seems sensible, as SFP+ equipment remains affordable and widely available. You might not need to upgrade immediately—Cat6a cables work well for 10 Gbps, and Cat6a is often stocked in switches. If you're considering higher speeds later, 10 Gbps fiber could be a smart move, but for now, the current setup should suffice.
You're considering a more advanced network configuration. Think about using a rack-mounted switch with plenty of ports—at least 20—and a patch panel. You might connect your ISP modem/router to the switch, then link it to the patch panel and distribute the connections throughout your home. Alternatively, you could incorporate fiber optic cables for key areas, routing them from the switch via SFP+ ports to a fiber switch before extending them around the house. Decide based on your needs and available space.
