VOIETOLT Cat8 Ethernet Cable 40M (40Gbps/2000MHz) – Flat STP RJ45 LAN Cable, White

What it is and why you’d buy a Cat8 40m cable

If your router and your devices don’t sit close together, a long Ethernet run can make day-to-day networking feel a lot more stable than relying on Wi‑Fi. The VOIETOLT Cat8 Ethernet Cable comes in a 40m length and is positioned as a high-spec wired option for faster, lower-interference connections.

On paper, this is aimed at situations where bandwidth matters (online gaming, streaming, and moving large files) and where signal quality is a concern (busy home offices, rooms with more electronics, or setups near interference sources). It’s also presented as a Cat8 cable with a listed maximum bandwidth of 2000MHz and up to 40Gbps, which is the kind of headline figure that makes sense for “best possible” wired performance—though it’s worth keeping expectations realistic about what your actual internet plan and devices can deliver.

Key takeaways: signal shielding and “flat” install

The standout feature in the description is the cabling and shielding approach. This Cat8 cable uses 4 twisted pairs that are described as S/FTP (shielded twisted pair) with copper construction. In plain terms: each pair is twisted (to help reduce interference) and the overall cable is shielded, which should help with stability in environments where EMI/crosstalk could otherwise cause issues.

It’s also a flat Ethernet cable. That can be a big deal when you want it to sit neater along skirting boards, under desk edges, or around doorways compared with a round cable that can snag or roll. It’s not “invisible”, but it’s often easier to route and manage.

Tech specs that matter for buying

Here are the details that most affect whether this makes sense for your setup:

• Length: 40m (so plan your routing before you commit)
• Category / performance claim: Cat8, up to 2000MHz bandwidth and up to 40Gbps
• Cable construction: 4 twisted pairs, S/FTP copper design
• Connectors: RJ45, described as gold-plated (50 microns) on both ends
• Compatibility claim: works with earlier standards such as CAT7, CAT6a, CAT6, CAT5e and CAT5

Worth noting: compatibility is stated broadly “with any device with an RJ45 port”. That’s helpful for real-world shopping, but it doesn’t guarantee full Cat8 speed in every scenario—your device and network hardware still play a part.

Where it shines in everyday use

This cable is easy to justify for buyers who want a direct, wired link for devices where latency and consistency matter.

For example, for a PS4/PS5 or a games PC, having a stable Ethernet connection can make a noticeable difference versus struggling Wi‑Fi in the same room. For streaming and video calls, a wired link can help avoid the “buffering roulette” that sometimes comes with wireless congestion. And if you’re regularly downloading large files or backing up data, the practical benefit is fewer interruptions and more consistent throughput.

It’s also pitched for typical home networking kit: routers, switches, modems, and even Smart TV connections—basically, anything with an RJ45 port.

What’s less convincing (and what to check)

This isn’t a product you’d choose purely for value if your devices only support older Ethernet speeds, or if your internet package can’t take advantage of the headline numbers. In other words, Cat8 can be overkill if your goal is simply “get online”, especially if your network hardware is limited.

Also, 40m is a long run. That can be totally fine, but before buying you should think about routing paths, whether the cable needs to cross busy areas, and how tidy you can keep it long-term. While the description emphasises durability, a long cable is still more likely to be moved during setup or rearranged later.

Durability and build: the part that affects longevity

VOIETOLT says the cable is built with a reinforced structure and a PVC outer cover that’s resistant to UV rays, plus flexibility and ageing resistance. It also claims it can handle more than 10,000 flexions, which is reassuring if you’re likely to route it through the same channel repeatedly, pull it into place carefully, or adjust your desk layout.

In plain terms, this is the kind of construction you’d look for if the cable is going to live somewhere “semi-permanent” rather than just being a temporary test lead.

Compatibility and requirements (so you don’t hit a snag)

You’ll need a device with an RJ45 Ethernet port on both ends of your setup. The cable is described as compatible with CAT7/CAT6a/CAT6/CAT5e/CAT5, so it’s not restricted to one generation of networking equipment.

That said, if you’re planning a very niche setup (for example, unusual adapters or splitters), double-check the ends and that you can physically route the 40m flat cable without sharp bends.

Mini FAQ

Will this cable work with PS4/PS5 and routers?

The description states it’s for devices with an RJ45 port, including PS4/PS5 and typical networking equipment like routers and modems, so it should be straightforward for those use cases.

Is the 40Gbps/2000MHz figure something I’ll always get?

It’s a maximum performance claim “on paper”. Real-world speed depends on your device Ethernet capabilities, your router/switch, and your internet connection. If your hardware is limited, you may not see the full headline rate.

Is 40m too long for gaming or streaming?

40m can be perfectly workable, but long runs are only as good as your routing plan. If you’re placing it across areas with interference or planning lots of movement, it’s worth thinking ahead.

Is a flat Ethernet cable easier than a standard round one?

Generally, flat cables are easier to route neatly and keep tidy along edges. They can still be a bit more rigid than some people expect, so treat routing carefully during installation.

Final verdict

When it makes sense

It’s a good fit if you want a long, wired Ethernet link (40m) for gaming, streaming, and reliable day-to-day connectivity, and you care about reducing interference thanks to the S/FTP shielding. The flat design and the durability claims also make it more convincing for setups that need neat routing.

It might not suit you if

It may not be a great match if your current network hardware only supports older Ethernet speeds and you’re buying purely to chase speed headlines. If you don’t need 40m, a shorter cable would usually make installation easier and reduce the amount of cable you have to manage.

Buying verdict

If you’re prioritising a wired connection that’s designed to stay stable in busier electronic environments—and you actually need that 40m length—this Cat8 VOIETOLT cable looks like a sensible, practical buy rather than a flashy extra.
