Supra Cat 7+ Ethernet cables

The previous Supra Ethernet cable was called: CAT 7+

Supra Cat 7+ shielded Ethernet patch cable, featuring "low smoke" Halogen-Free insulation

This cable is now discontinued but may still be available from some retailers. It is much better than standard Cat-5/Cat-6 E cables, as it has a much wider bandwidth.

Supra Cat 7+ cables are shielded and wide-bandwidth, (upto 1300 MHz) and are ideal if you have local data storage (such as a NAS box containing ripped CD's and/or DVD's) and you want to share music and especially video files around your home or office network.

Each Cat 7+ cable uses 8P8C terminations, allowing suitable hardware to benefit from all four twisted pairs of network cable.

Using Cat 7+ cables, with Gigabit type ethernet ports is a much faster way of sharing large data files, (compared to wifi) as firstly, you have a dedicated port that isn't going to be shared and secondly, wifi networks are not as speedy and there's more chance of interference and buffering as a result of other signals in the 2.4GHz or 5GHz band that might be sharing the same wifi channel.

So, consider wiring Cat 7+ cables from your router to your NAS box as a minimum...and then at least another Cat 7+ from router to internet connected TV for watching Netflix in 4K, for instance) and then perhaps additional Cat 7+ cables to your primary desktop PC(s).

Supra Cat 7+ cables are designed for maximising data throughput in both domestic and commercial environments, when used with matching 10Mb/100Mb/1000MB networking systems. Low insertion loss and both individual and overall shielding help to minimise losses, especially when used in data intensive applications, such as video streaming.

In fact, these cables are ideal for connecting between NAS boxes, media servers, wired set top boxes (Roku, Humax etc), routers and internet connected TV's. For maximum data transfer, please use the Gigabit ethernet sockets provided on most newer equipments.

Using Supra Cat 7+ shielded ethernet cables can help to maximise video, audio and data performance whilst streaming from your local network connected appliances.
