Distributing twisted pair around the house, it is better to use shielded or ordi

Best answers

Should I use shielded or unshielded Cat6 twisted-pair cable for a home installation between the patch panel and wall sockets?

For a home installation, unshielded cable is enough and it should not affect network operation; shielding is mainly useful in industrial environments with strong electromagnetic fields [#16871260][#16871265] If you choose shielded cable, the whole installation must be done correctly and grounded, otherwise it can cause problems instead of benefits [#16871265][#16871268] Do not buy the absolute cheapest cable; choose a proven copper cable, not CCA (copper-plated) [#16871260][#16871268][#16871281]

    Hello,
    I've been wanting to run cables all over the house for a long time. I'm going to invest in cables and switch categories 6.
    Should the cables from the patch panel to the sockets be shielded or can they be unshielded, the cheapest? Will this affect network performance?
    I found a similar topic probably from 2007 but a lot of things may have changed since then.

    In domestic conditions, unshielded ones are enough.
    However, I would not take the cheapest cable, but a proven copper one.

    By proven, do you mean just more well-known companies or any in particular?

    In home conditions, it will not affect the operation of the network. It is important in industrial facilities where large electromagnetic fields are generated. But if you do a full installation with grounding and use shielded cables, you will have the satisfaction of a professionally made infrastructure ;-) .

    And if you do something wrong with a shielded cable, you will have problems instead of satisfaction.

    Proven, with copper strands, not copper-plated.

    Unfortunately, most of the cables on the market are CCA.
    I bought copper to order.

    I put Cat at my place. 6a Alanteca, in my opinion a very good twisted pair.
    Isn't it better to put 6a than 6?

    Preferably 8, but I'm not sure if my budget is of the same opinion ;)

    ----/EDIT/----
    Do you think that such a set plus cables will be a good start to start your adventure with running a network at home xD

    If the spool is still Bitner.
    Chinese brands write 100% Cu or write nothing. From Chinese oems, I can recommend ready-made Logilink and Dugitus patchcords.

    The 6U cabinet is a colossus for home use.
    Lip clamper, look for another. OK.
    I would choose a managed switch.

    I have a similar switch - TL-SG1016DE (probably I wouldn't take it a second time) sometimes it behaves strangely, as if it would restart - once every 2/3 months. Maybe he got kicked after the storm, even though he was grounded, once his brother-in-law said that his cabinet caught fire like a Christmas tree (it's hard to say something because he's not supervising him). Maybe something from Netgar.

    On Allegro you can get something class HPE 1820-24G used for about PLN 300. Good gigabit hardware, SFP, STP, vlans, etc.

    Speaking of these sockets, they are huge. Intelinet has such a nice little surface-mounted

    Unfortunately, I do not have the ability to forge in the walls, I intend to lead it through the attic with white slats and put the connectors on the wall, unfortunately I have no way to drill, I have to do everything on the wall. So you think it's better to aim at NETGAR than TP-Link? As for a managed switch, what does that get me? I once had experience with a TP-Link desktop switch for 5 ports, everything worked perfectly, so I don't know why I should look there. I don't really need vLan stuff, the only "server-like" connection, apart from computers and printers, is maybe a Synology network drive and a CCTV system.

    --/EDIT/--
    And as for the crimpers, could you help me find a good one for PLN 40? I'm not going to buy a super professional one for PLN 200 because probably my adventure with networks will end for some time after laying it, but I also don't want something that will fall apart when I barely touch it

    Maybe you don't need a switch, instead you can invest in a router something like MikroTik MT RB2011UiAS-2HnD-IN.
    You have 10 LAN ports, 1 SFP for optical fiber and usb for modem and wifi. The disadvantage is that it is equipment for advanced networkers. ASUS RT-AC1200G+ only few LAN ports.

    The best inexpensive crimper is a classic one, e.g. Cablexpert T-WC-01 other brands in this style.

    My ISP situation is very complicated, so I prefer not to touch the router :) However, I really want to create the entire network based on a gigabit network, and in the future using cat. 6 cables, maybe 10GBPS. If you could provide the exact link to the crimper, I would be grateful, they all look the same to me

    In Leroy Merlin I bought a set - crimper + tester + LSA press tool + insulation stripper for PLN 119.
    It's good for homemade.

    Then you can't tighten the plugs on the cable. The part built-in with a 'wire' from the panel to the sockets, depending on the manufacturer, the so-called 'knife' or 'toolless'. Required high culture "in hand" and repeatability, which you can't learn from the internet.
    Cables (patchcords and station cables) with strands, factory-made.
    Clamping the plugs on the cable in the range you write about NEVER happens.

    On makeshift Gb it may work, it may not work, or the worst thing is that it works "sometimes".

    Here's a similar thread:
    https://www.elektroda.pl/rtvforum/topic3401980.html

    From the popular cables, I recommend Telefonica or Bitner. No Chinese.
    Wires always terminated with a socket on one side and a panel on the other. Ready-made patch cords between devices and sockets, not self-made.
    Keystones e.g. A-LAN and you don't need any tools (read "experience in use").

    Active Equipment:
    TP-Link - great home routers for DSL. The rest is a lottery, especially gigabit devices.
    Mikrotik - not for beginners, unstable, buggy software.

    From inexpensive:
    The lowest models of HP Enterprise, 3Com, Ubiquity.

    Ah 3com good hardware but absorbed by HP ages ago.
    Maybe someday some fan will buy the rights to the brand and revive the brand, for now it's over :-( :-)

Topic summary

✨ The discussion revolves around the choice between shielded and unshielded twisted pair cables for home networking, specifically using Category 6 cables. Participants agree that unshielded cables are generally sufficient for domestic environments, as electromagnetic interference is minimal compared to industrial settings. However, they recommend investing in high-quality copper cables rather than cheaper copper-clad aluminum (CCA) options. Various brands and models of cables and switches are suggested, with emphasis on the importance of proper installation and grounding. Users also discuss the necessity of a good crimper for cable preparation and the potential benefits of managed switches for advanced networking needs.

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?

  1. 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].
