Copper breakthrough

May 2004
Australian Personal Computer;May2004, Vol. 24 Issue 5, p121
Truly high speeds have eluded Ethernet users for more than three decades, but all that changed overnight with 10Gigabit Ethernet. Scientists transporting black hole gravity wave data at the Lawrence Berkeley National Laboratory succeeded in achieving 10,000MB/s, or 10 billion bit/s — proving that humble Ethernet could step up to the big league in data speeds. Transferring those lab speeds to garden variety PCs will rely on next generation Ethernet technology now in development. Among them is 10Gbase-T, which will allow 10Gbit speeds over twisted pair copper cabling, rather than expensive optic fibre. The technology promises distances of 100m on four-pair Class F copper cabling, or between 55m and 100m on Cat 6.
