CAT 8 (Category 8 Network Cabling)
If you’ve been in LAN cabling business, you would have heard about CAT-5E, CAT-6, Cat-6A and probably CAT-7 standards. It would not be therefore hard to guess that the next standard in network copper cabling would be CAT-8 (Category 8) standard.
Whilst most contractors are still debating the pro and cons of installing Cat-6A over Cat-6, the TIA and ISO (Worldwide Cabling Standards Committees) are well ahead of us.
Currently there are a number of similar but different Category 8 (Cat-8) solutions being considered by the standards bodies for 40Gb/s over twisted pair copper.
In the USA TIA/EIA is considering Cat-8 based on an extended performance Cat-6A cable. Meanwhile in Europe ISO/IEC is looking at two options currently tagged Cat-8.1 based on an extended performance Cat-6A cable and Cat-8.2 based on an extended Cat-7A cable. Interestingly all of these are based on shielded cables and connectors
So whats behind this?

The main benefits of this proposed standard will be the ability to offer a true 40Gig copper cabling solution which is the demand of the Data Centre operators.
Another important use of increased bandwidth will be multimedia for home use and this could be a big incentive/opportunity for Australian contractors with the continuing deployment of the NBN high speed network. While traditional cabling solutions of Cat-5e and Cat-6 only offer bandwidths up to 250MHz, the proposed bandwidths of Cat-8 are well in excess of 1Gig and will comfortably run satelitte and television signals on the same cable as telephone and data.
