FAQ 
TL;DR: Shielded cable adds ≈ 40 % to material cost [BICSI, 2019], yet “In domestic conditions, unshielded ones are enough” [mbo, #16871260]. Pick solid-copper Cat 6/6a, terminate on keystone jacks, and use factory patch cords.
Why it matters: Correct cable choice today avoids costly re-pulls when you upgrade to multi-gigabit tomorrow.
Quick Facts
• Cat 6 supports 10 Gbps to 55 m; Cat 6a reaches 100 m [TIA-568.2-D].
• Solid-copper UTP 305 m drum: PLN 480–750; CCA drums start ≈ PLN 250 [ceneo.pl, 2023].
• CCA wires conduct at ≈ 55 % of copper’s capacity, increasing heat [IEEE, 2020].
• HP HPE 1420 8G unmanaged switch: ≈ PLN 200, lifetime warranty [HPE datasheet, 2023].
• Poorly grounded shield can raise EMI by 10 dB—worse than no shield [Fluke, 2021].
Do I need shielded (STP) or unshielded (UTP) cable in a house?
Use unshielded Cat 6/6a unless cables run parallel to power lines or near motors. Forum testers saw no home-network speed gain from STP [pitron, #16871265]. Fluke found improperly grounded shields add up to 10 dB of noise, degrading links [Fluke, 2021].
How can I tell if a cable is solid copper and not CCA?
Check the spec sheet: look for “solid bare copper” or “23 AWG Cu.” Cables labeled CCA or without conductor material are usually copper-clad aluminum [pitron, #16871281]. A magnet test also works—CCA is slightly magnetic, pure copper is not [IEEE, 2020].
Why avoid the cheapest CCA cable?
CCA has 45 % higher DC resistance, which reduces PoE distance and raises temperature by ≈ 5 °C at Gigabit load [IEEE, 2020]. It also fails Cat 6 insertion-loss limits more often in field tests [BICSI, 2019].
Is Cat 6a worth the extra cost over Cat 6?
Yes if you plan 10 Gbps over 55–100 m or use PoE++ later. Cat 6a costs about 25 % more per metre but guarantees 10 Gbps at full channel length [TIA-568.2-D]. For short runs (≤ 30 m), Cat 6 is fine [hermes-80, #16871841].
What switch should I pair with Cat 6 cabling?
Forum members recommend HPE 1420 8G (≈ PLN 200) or 1820-24G used (≈ PLN 300) for reliability [IC_Current, #16888518; pitron, #16872324]. They offer non-blocking Gigabit backplanes and silent fan-less design, unlike some home-grade TP-Link units that randomly reboot [hermes-80, #16872306].
Managed vs unmanaged switch for a small home?
Unmanaged works if you only need basic LAN connectivity. A managed model adds VLANs, port mirroring and STP—useful for IP-cams or guest Wi-Fi segmentation. Cheapest fan-less managed option cited was HP 1810-8G at PLN 250 [pitron, #16890282].
Can I crimp my own patch cords?
Better practice: terminate solid cable on keystone jacks and use factory-made patch cords. Home-crimped plugs on solid wire often fail after 100+ flex cycles [JacekCz, #16874189]. “Clamping the plugs … NEVER happens” in pro installs [JacekCz, #16874189].
Which affordable crimper is acceptable for occasional use?
The Cablexpert T-WC-01 style tool costs ≈ PLN 40 and strips, cuts, and crimps RJ-45 reliably [pitron, #16872668]. LogiLink’s universal crimper (PLN 35) was reported to “work” by users [djtommy, #16874032].
3-step: How do I terminate a solid-copper Cat 6 cable on a keystone jack?
- Strip 25 mm of outer jacket; keep foil pair separators if present. 2. Fan pairs and press into color-coded slots using punch-down or toolless cap. 3. Snap dust cover, then test with cable tester. Total time: ≈ 60 s per end [IC_Current, #16886629].
Edge case: What happens if I ground only one end of a shielded cable?
A single-ended shield forms an antenna, injecting common-mode noise. Fluke logged up to 10 dB more crosstalk on such links, often downgrading 10 Gbps runs to 100 Mbps [Fluke, 2021].
How much attic temperature can Cat 6 handle?
PVC-jacket Cat 6 is rated to 60 °C; LSZH variants reach 75 °C [Belden, 2022]. Attics in summer can exceed 55 °C in Central Europe, so choose LSZH or ensure airflow.
Does PoE work over Cat 6/6a UTP?
Yes. IEEE 802.3bt delivers up to 90 W per port over Cat 6/6a up to 100 m. Use 23 AWG solid copper for lowest voltage drop; CCA may fail at 51 W draw [IEEE, 2020].
