Types Explained
Cat 6
Supports up to 10 Gbps at 250 MHz, with unshielded twisted pair (UTP) construction. The standard for most home networks.
- Affordable and widely available
- Handles gigabit internet with ease
- Flat designs available for easy hiding
- Limited to 10 Gbps over shorter distances
- Not future-proof for multi-gig WAN
- Unshielded cables can pick up EMI
Best for: Budget-conscious buyers with ≤1 Gbps internet
Example: Jadaol Cat 6 50ft (under $10)
Cat 7
Up to 10 Gbps at 600 MHz, fully shielded (S/FTP) with each pair individually foil-wrapped. Offers better noise resistance than Cat 6.
- Higher frequency reduces crosstalk
- Fully shielded for clean signal
- Still affordable for short runs
- Rigid and bulky, harder to install
- Performance gains over Cat 6 are minor for most users
- Less common at retail
Best for: Enthusiasts wanting extra EMI protection
Example: DbillionDa Cat 8 6ft (under $7)
Cat 8
Supports up to 40 Gbps at 2000 MHz, with heavy shielding and thicker gauge. Designed for data centers and future home networks.
- Future-proof beyond 10 Gbps
- Excellent shielding and durability
- Available in flat, braided options
- Overkill for sub-gigabit internet
- Thicker and stiffer cables
- Short distance limitation (30m for full speed)
Best for: Power users planning a 10GbE upgrade or gaming on LAN
Example: UGREEN Cat 8 10ft Braided (under $10)
What Actually Matters
| Factor | Importance | Best brand |
|---|---|---|
Cable Category Cat 6 for gigabit; Cat 8 for multi-gig Match category to your router and internet plan; Cat 6 handles 1 Gbps, Cat 8 future-proofs for 10 Gbps. | Must-have | Jadaol (Cat 6), UGREEN (Cat 8) |
Cable Length Measure exact run + 1–2 ft slack Too short forces couplers; too long creates excess slack. Most homes need 10–50 ft. | Must-have | Jadaol (long cables), DbillionDa (short) |
Shielding (STP vs UTP) S/FTP for near power lines or outdoor use Shielding prevents electromagnetic interference; essential for outdoor or industrial settings, optional for home. | Nice-to-have | Orbram (shielded flat) |
Wire Gauge (AWG) 26AWG or lower for PoE devices Thicker wire (lower AWG) handles PoE better and lasts longer; 30AWG is fine for data-only. | Nice-to-have | UGREEN (26AWG braided) |
Gold-Plated Connectors Gold-plated contacts add marginal corrosion resistance; standard nickel-plated RJ45 plugs work reliably for decades. Save the premium. | Marketing BS | — |
Budget Tiers & Top Picks
What to buy at each price point — and exactly where spending more stops paying off.
Budget Short Patch
Under $7
Stop paying more: At $6.89, this is the cheapest way to get Cat 8 speed; spend more only if you need extra length or braiding.
When to upgrade: Need a longer cable? Step up to a 10 ft Cat 8 braided cable for around $10.
Mid-Range Long Flat
$8–$10
Stop paying more: You get a flat, easy-to-hide 50ft cable for under $10; no need to pay more for longer lengths in this category.
When to upgrade: Want faster speeds for future-proofing? The same brand makes a 25 ft Cat 8 flat cable for the same price.
Premium Durable Braided
$10
Stop paying more: The braided jacket and 26AWG wire justify the $10 price; you won’t find a more durable Cat 8 at this price.
When to upgrade: For outdoor exposure, consider the weatherproof Orbram flat braided cable.
Common Mistakes to Avoid
Buying too short
A 3ft cable that doesn't reach wastes money; always measure and add 2 ft for slack.
Cost of getting it wrong: Replacing with a longer cable costs double.
Paying for Cat 8 with a 100 Mbps plan
Cat 8 supports 40 Gbps, but existing internet typically maxes at 1 Gbps; Cat 6 is enough.
Cost of getting it wrong: Extra $5–$10 per cable, plus stiffer cords.
Ignoring shielding for outdoor runs
Unshielded cable near power lines or outdoors can pick up interference, causing packet loss.
Cost of getting it wrong: Intermittent connection drops mean redoing the install.

Frequently Asked Questions
What is the best Ethernet cable for gaming?
Even if your internet is slower, the shielding prevents interference. If you're on a budget, a Cat 6 50ft like Jadaol works fine for most online games. A shorter cable reduces signal loss—use 10–15 ft for a desktop near the router.
How do I know what length Ethernet cable to buy?
Measure the exact path from your device to the router, then add 2–3 feet for slack. Avoid stretching the cable tightly. The Jadaol Cat 6 50ft covers most living rooms, while the DbillionDa 6ft is perfect for a nearby console. If you're wiring through walls, allow extra for in-wall routing.
Is Cat 8 worth it over Cat 6?
Only if you have internet faster than 1 Gbps or plan to upgrade to a multi-gig router soon. Cat 6 handles full gigabit today. The extra shielding in Cat 8 helps in noisy environments, but for most homes, Cat 6 is sufficient. You'll save money and gain a more flexible cable.
Can I run Ethernet cable outdoors?
Yes, but use weatherproof cables like the DbillionDa Cat 8 6ft or Jadaol Cat 8 25ft Flat, which are UV-resistant and waterproof. Avoid unshielded Cat 6 outdoors—moisture and sun degrade the jacket. For permanent outdoor runs, bury the cable in conduit.
What is the difference between flat and round Ethernet cables?
Flat cables are easier to hide along baseboards and under carpets, but they typically have thinner gauge (30AWG) and can't match the durability of round braided cables. Round cables are better for rugged use and PoE, while flat ones excel in clean installations like a home theater.
Do gold-plated connectors make a difference?
Gold-plated connectors resist corrosion slightly better than nickel, but for indoor use in a dry home, standard nickel contacts work flawlessly for decades. Don't pay extra for gold unless you live in a very humid climate—it's mostly marketing.
