Beyond Category 5: The Development of Copper Cabling Requirements for Gigabit Ethernet
Overview Category 6 does not exist yet - the first published specification will probably not be available before December 2000. There are no current applications which demand Category 6. “Good quality” Category 5 systems will support Gigabit Ethernet in the majority of cases however Enhanced Category 5 systems will allow transmission speeds of at least 1Gbps using current technology with more assurance. The cost increases implicit in Category 6 and 7 cabling systems and the reductions in the cost of fibre NIC’s point to fibre being potentially more cost effective as a long term solution. As the exploration of Gigabit Ethernet continued it became clear that the transmission technology required to achieve 1000 Mbps over a 100 metre distance was not adequately supported by the physical manifestation of a minimally compliant Category 5 channel as defined by EIA/TIA 568 et al. It is important to realise that when the category 5 specification was originally drafted the highest speed data networking protocols were the now ubiquitous 10 Base T Ethernet variant and the less common 16 Mb Token Ring system.
