5.3 Fast Ethernet

100Base-TX and 100Base-FX are called "Fast Ethernet." This is because they use the Ethernet CSMA/CD access rules and data packet structure, but data travels ten times faster (100Mbps) than traditional 10Mbps Ethernet.

Below is a list of the cable types and connectors that supported by Switch for 10Base-T, 100Base-TX, and 100Base-FX networks.

In many cases, 10Base-T LANs can quickly and easily upgrade to 100Base-TX networks. Also, 100Base-FX will become more popular due to its longer range. Table lists the maximum Fast Ethernet connection distances.

NOTES: 1) "DTE" is an end-station such as a PC or switch port

2)Copper+Fiber assumes the max. Copper length is used

3)"Repeater" is a standard hub, NOT a Switch.

4)Half-/Full-Duplex. Fiber's distance depends on mode.
