Cat 8 Network Cable, CAT8 Cable, Ethernet Cable CAT8 Application
Cat 8, the latest generation of dual shielded (S/FTP) network cable
with 4 pairs, supports 2000MHz of bandwidth and reaches up to 40Gb/s at
30 m, especially useful for connecting servers, switches, patch panels,
and other devices in the data center.
Compatible with Cat 7/7A and Cat 6A, Cat 8.1/8.2 supports 25G Base-T at more than 30 m (tentatively) and 10G Base-T at 100 m, applies in high-speed and bandwidth-intensive locations outside
the data center, and meanwhile supports Power Over Ethernet (POE/POE+).
Features
Cat 8.2, 8-core S/FTP shielded cable, uses pair shield and overall shield structure, with a separate aluminum foil shield for each pair and an overall
tinned copper mesh braided shield.
This optimizes Near End Crosstalk/Far End Crosstalk (NEXT/FEXT) and
Alien Near End Crosstalk (ANEXT) performance, thus resulting in a
maximum transmission frequency of 2000MHz.
