CAT8 Ethernet Digital Network Cable, by Supra Cables.

Supra Cat 8 is once more one step ahead by providing a future proof cable, e.g. 40GBASE-T over one single cable. It is used beneficially in TCP/IP and UDP applications where bit-correct, jitter-free data transmissions is critical, e.g. 4K and 8K video streaming, high quality music streaming (e.g. 32 bits @ < 700 kHz for some downloadable music and in-studio applications), gaming and data centres, and in-building installations such as hotels, conference facilities, among others.

Supra CAT8 is also available factory terminated as patch cables in a number of standard lengths, pre-connected with Supra RJ45 Connectors, a fully shielded connector supporting the astonishing performance of the cable also under tough service conditions and it is possible to connect on-site.

HDBaseT is transmitted over 6A up to 100 m (328 ft) long, with 8P8C modular connectors of the type commonly used for ethernet local area network connections. From Cat 6A to Cat 8 the step is four times the bandwidth. Supra Cat 8 allows for 2,000 MHz(!) an incredible transfer speed providing for quality enhancing massive headroom.

HDBaseT transmits uncompressed ultra-high-definition video (up to 4K), audio, power over HDBaseT (PoHDBaseT - up to 100W), Ethernet, USB, and a series of controls such as RS and IR.


  • Performance better than 8.2 according to preliminary specification IEC 61156-10 - Astonishing future proof transfer speeds.
  • Excellent NEXT (= crosstalk), very low dampening and mutual lead pair interference - Bit correct transfers.
  • Low dampening - Long cable lengths without signal degradation or voltage drops for PoE.
  • Excellent shielding, both pair and total - Almost completely interference immune with very low pick-up.
  • Low jitter, perfect timing - Very low bit stream timing errors gives low needs for error corrections, thus high transfer speeds.
  • Bandwidth at 2,000 MHz
  • Flame retardant, halogen-free - Allowed in public spaces and buildings.
  • Made in Sweden.
