Chapter 1: Introduction Switching Technology The Ethernet Switch allows simultaneous transmission of multiple packets via an internal high-speed data channel. This means that it can partition a network more efficiently than bridges or routers. The Ethernet Switch is therefore fast being recognized as one of the most important building blocks for today’s networking technology.
Fast SwitcHub-2se User’s Guide Accton’s Smart Extender Accton’s Fast Switch-2se can boost network bandwidth fourfold (i.e., if running at 100Mbps and using full-duplex operation for both ports). It provides one 10/100 Mbps RJ-45 port for 10BASE-T or 100BASE-TX media attachment (which is automatically detected by the switch), and one 100 Mbps fiber optic port for 100BASE-FX media attachment via an SC or ST type connector.
