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.
