pThis module provides an ultra-high-performance 10 Gigabit Ethernet connection. 10 Gigabit Ethernet is a standards-based method for connecting at performance 10x that of Fast Ethernet, at 10 Gigabits per second, while retaining critical Ethernet properties such as pack format.The module requires a XENPAK-style transceiver, sold separately, to provide the physical media connection./pp10Gigabit Ethernet is the perfect aggregation technology when deploying gigabit to the desktop or for interconnecting core and distribution switches. Use a 10Gigabit Ethernet connection for the SuperStack 3 Switch 3870 to connect to a 3Com Switch 7700 with a similar module, to a higher-performance 10-Gigabit capable aggregation switch like the 3Com Switch 8800, or to another switch with a standards-based 10GBASE-X connection. /p
