Description
The AT-FS20x and AT-FS202SC/FSx Series Switches include the following
models:
The AT-FS20x Series switches are designed to extend the distance of your
network by converting Fast Ethernet data between twisted-pair cabling and
either multimode or single-mode fiber optic cabling. These dual-port switches
can also be used to improve the performance of your network by dividing it
into smaller, more manageable segments.
Each switch features a 100Base-FX fiber optic port and a 10Base-T/
100Base-TX twisted-pair port. The fiber optic port has either a SC or ST
connector and a maximum operating distance of 2 kilometers (1.2 miles) to
100 kilometers (62 miles), depending on the model. The twisted-pair port has
an RJ-45 connector with a maximum operating distance of 100 meters (328
feet).
The fiber optic port operates at 100 Mbps, while the twisted-pair port operates
at 10 Mbps or 100 Mbps. Both ports feature half- and full-duplex operation.
All of the AT-FS20x Series switches can be installed on a desktop or in an
AT-MCR12 chassis. These switches are easy to install and do not require
software configuration or management. This guide provides installation
instructions for installing the AT-FS20x Series Switches on a desktop. To
install the switches in an AT-MCR12 chassis, see AT-MCR12 Chassis
Installation Guide (PN 613-10725-00).
