The SUPRA CAT8 is a sturdy cable providing extreme performance with a bandwidth of 2000MHz. Flame-retardant and double-shielded, it does an excellent job in avoiding lag in audio or video. It is also still backwards-compatible with standard Cat 6A. The custom lengths come with Future Shop custom terminations, made of nickel-plated zinc by Telegärtner.

SUPRA CAT8 Flame Retardant Ethernet Cable - Custom Length

 

The SUPRA CAT8 is a sturdy cable providing extreme performance with a bandwidth of 2000MHz. Flame-retardant and double-shielded, it does an excellent job in avoiding lag in audio or video. It is also still backwards-compatible with standard Cat 6A. The custom lengths come with Future Shop custom terminations, made of nickel-plated zinc by Telegärtner.

What SUPRA say

SUPRA Cat 8 is one step ahead by providing a future proof cable supporting up to 40GBASE-T over a single cable. It is backwards compatible with standard Cat 6A. Supra Cat 8 is terminated with an improvement of the widely used RJ45 to be able to support the extreme performance that Supra's  cable provides. It ups the performance 4 times from Cat 6A with a bandwidth of 2000MHz. Supra Cat 8 is used advantageously in TCP/IP and UDP application where correct data information is critical, e.g. 4K and 8K video streaming, high quality music streaming, gaming, data centers and in-building installations. By upping the performance 4 times to 2000MHz you are more likely to have no incorrect data being sent or not being corrected by applications in time as there is much more bandwidth to work with. This can be very important to avoid for example video loss in streaming or avoiding stuttering in music streaming and voice communication. Supra Cat 8 is constructed with double shielding instead of single shielding to best avoid interference and in so data losses than can be critical to applications It is also ideal for Power of Ethernet (PoE) applications as it has larger copper cross-section than Cat 6A, meaning high power and less voltage drops.

Capability characteristics:

Better than Category "8.2" acc. to draft IEC 61156-10, excellent NEXT, low attenuation, excellent screen properties (pair- and overall screen), low Skew bandwidth 2000 MHz.

Applications:

Connecting cable and patch cord for generic cabling systems acc. to ISO/IEC 11801 and EN 50173 (2nd edition) and for data centre cabling acc. to ISO/IEC 24764 and EN 50173-5 as well TR 11801-99-1. Ideal for all applications of class D up to FA and Class II, Multimedia (TV, Video, Data, Voice) >40 GbE acc. to IEEE 802.3 bq (draft), Cable sharing, VoIP, PoE/PoE+.

Smooth and laid back

Verified Buyer
The cable took about 60 hours to run in, but after that, it was quite pleasant and laid-back to listen to. However, I was left wanting some excitement, so I might try something else in the future.

However, If your system is quite bright, then this cable will work wonders I’m sure.

Great cable and service from Future Shop
6 Jul 2024
Verified Buyer
A great cable with solid construction especially with the Telegartner RJ45's. Brought obvious improvements to my streamer in all areas.

The cable itself isn't the most flexible, which may be an issue for some, and the colour may not appeal to all, but if neither of those is a problem, you can't go wrong at this price.

Great service from Future Shop.

Reasonable cable, good service
28 Feb 2024
Verified Buyer
Supra 8 cable is okay, but no more than that. Having a very neutral high-end set, the Supra sound makes the sound a bit shrill (especially violins).

The Cat 7 cable I had before was more comfortable. Maybe it takes more time?

Shipping service Futureshop is good.

Being able to choose a short cable of suitable length is a great plus. The Supra is of good value and is in a different league to most Ethernet cables. Makes a really positive contribution to the sound quality from my streamer.

Termination with Telegartner RJ45 works well. These are top-draw connectors. I can thoroughly recommend it.

Great service as ever from Future Shop.

Massive improvement over stock patch cables
9 Jan 2024
Verified Buyer
This is the best value of the so-called audiophile ethernet cables. Replacing the cat5e patch cable (2m length) between the model and router made a huge difference, especially with stereo imaging and the dynamics of the music.

Replacing a cheap UGreen cat8 cable between the router and my streamer (8m length) the changes were much more subtle but still noticeable. Most audiophile cables talk about increased bandwidth from the materials they use - however, the Cat rating is a measure of this.

This is one of the few cat8 cables available, and it is not stupidly priced like some of the competition, which is often only Cat6 (lower bandwidth despite claims). The custom cable also comes with higher quality plugs, usually only seen on the top of the range cables. So, I class this as a bargain in this crazy audiophile world.

I use the cable connecting router and Samsung 55” Quantum Dot OLED 4K TV. It performs to my expectations. The displayed colours are very vibrant.

Of prime importance, QD OLED TV particularly needs to control its brightness, where the cable does the job.

Really good cost-effective cable, and you can choose the exact length you need if terminating yourself or can get this done for you. After doing a few of these, I would recommend getting the professionals to add connectors, as it isn’t as easy as it seems.

Overall fantastic service and all orders arrived the next day.

Excellent cable
4 Dec 2021
Verified Buyer
I ordered this cable to replace a generic cable from my NAS to switch. I chose Telegartner plugs as these provide a very secure connection. I was pleasantly surprised by the further sound quality increase achieved by adding this cable. It perfectly compliments the Audioquest Carbon running from my switch to streamer.

Excellent service from Futureshop again with next day delivery.

Ordered this on Sunday, cable was produced Monday and with me on Tuesday, excellent service from Future shop.
Cable was purchased to improve the streaming of Netflix and Amazon Prime in my home cinema system.
(I was using just a bog standard cat 5 cable previously.)

This has elevated my viewing enjoyment immensely.
Picture quality now looks like Blu-ray quality from both these video services.
Audio has also improved, with it sounding very natural and life like.

The cable has made a substantial improvement for not too much outlay, with great service from Future Shop.
PS. I recommend the Telegartner connectors, can't say exactly what improvement they bring but they are part of the new cable 'package'.

Got a 13m cable to run from by router to a Paul pang quad network switch. While the cable is great for this length and to connect the router to the switch I found it a bit harsh when connecting the switch to my streamer. The audioquest carbon is a better and reasonably priced cable to use between the switch and streamer with a more relaxed and detailed sound.

Good cable. I have ordered some Ethernet cables else were before, but they where poor quality. This Supra is a real quality one! Although it is not so flexible (and maybe the light-blue colour is not everyones choice) it works really good for my HiFii-Streaming music.

The connectors are really solid. I can highly recommend this cable.

I run this cable on my Lumin A1. I have a simple switch on one side and my lumin on the other side. Compared to many other cables I tried, it is very smooth and melodic. Voice has a lot of presence and density. The soundstage is good. Not amazing but good. It is not aggressive like a lot could be but it neither warm. The resolution is not amazing. I balance it on the NAS side with a cat 6, this is a perfect fit I found. All in all, compared with many other cables I tested, it is adopted and will stay on my system.
