思科系统公司宣布,Catalyst 4000系列产品是第一套能以10、100、1000Mbps的速率进行互操作的高密度平台。这得益于它开发出的桌面统一以太网技术,这种技术是通过用铜线进行传输的高密度千兆以太网模块实现的,主要用于思科Catalyst 4000系列交换机。这种模块完全符合IEEE 802.3以太网标准。用户可通过5类线,以每秒10、100或1000兆的速度访问网络。用户在获得1000Mbps性能的同时,还需要考虑到旧PC和打印机等设备
Cisco Systems announced that the Catalyst 4000 Series is the first high-density platform to interoperate at 10, 100, and 1000 Mbps. This is due to the desktop unified Ethernet technology it developed, which is implemented using high-density Gigabit Ethernet modules that are transported over copper wire and is used primarily in Cisco Catalyst 4000 Series Switches. This module is fully compliant with the IEEE 802.3 Ethernet standard. Users can access the network at a rate of 10, 100, or 1000 megabits per second over Category 5 lines. Users need to consider old PCs, printers, and other devices while achieving 1000Mbps performance.
