Technology Basics

Fast Ethernet is a network technology specified by IEEE Standard 802.3u. It extends the traditional 10Mbps Ethernet technology

to achieve 100Mbps transmission and reception, while retaining the same CSMA/CD Ethernet protocol. Thus, while Fast Ethernet

provides a tenfold increase in network capacity, it is wholly compatible with traditional 10Mbps Ethernet network facilities. This

compatibility is the key to easy and efficient upgrades to 100Mbps in your network areas needing greater bandwidth. Upgrading

selected areas to Fast Ethernet does not require hardware or software changes in network areas where traditional 10Mbps Ethernet

is providing good service. For upgrading, Fast Ethernet is the clear choice in terms of cost-effectiveness, as well as convenience

and smoothness in transition.

Category 5 cabling is required for 100Base-TX Fast Ethernet in order to provide full duplex operation. Full duplex 100Base-TX

operation allows simultaneous transmission and reception, both at 100Mbps, thus providing service potentially equal to 200Mbps

full-duplex service.

To provide compatibility in traditional 10Mbps Ethernet environments (where, for example, DFE-530TX+ adapters are installed

anticipating upgrade of supporting switch equipment to Fast Ethernet), the DFE-530TX+ also supports traditional 10Mbps

Ethernet operation, in full-duplex as well as half-duplex modes. Selection of the best operation mode in any given installation is

automatically governed by auto-negotiation.
