The AT-MC100 Series Fast Ethernet Media Converters are designed to extend
the distance of your network by interconnecting LAN devices that are
physically separated by large distances. Each media converter features a
100Base-TX twisted pair port and a 100Base-FX fiber optic port. The twisted
pair port has an RJ-45 connector and a maximum operating distance of 100
meters (328 feet). The fiber optic port has an ST or SC connector and a
maximum operating distance of 2 kilometers (1.2 miles) to 100 kilometers (62
miles), depending on the model. These units operate at 100 Mbps and feature
half- and full-duplex operation.
The media converters can be installed on a desktop or in an AT-MCR12
chassis. The AT-MC100 Series Media Converters are easy to install and do not
require any software configuration or management. Figure 1 shows an
example of an AT-MC100 Series Media Converter.
