With the IEEE's formal ratification of the 1000BASE-T standard in June of 1999, the promise of Gigabit Ethernet networks which could take advantage of ubiquitous category 5 copper cabling became a technical reality. However, up until the recent availability of cost effective silicon solutions for the switch controller and transceiver, the widespread commercial deployment reality has been a very different story. Although first generation 1000BASE-T Network interface Card (NICs) and low port density switches have been available for almost two years, the power consumption, primary systems component costs and design complexity of these first generation products have been too high compared to their 10/100 Ethernet predecessors.
