Chapter 1

Description

The AT-FS20x and AT-FS202SC/FSx Series Fast Ethernet Switches include
the following models:

❑ AT-FS201 ❑ AT-FS202SC/FS2
❑ AT-FS202 ❑ AT-FS202SC/FS3
❑ AT-FS202SC/FS1 ❑ AT-FS202SC/FS4

The AT-FS20x and AT-FS202SC/FSx 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 10/100Base-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 a 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.

AT-FS20x and AT-FS202SC/FSx 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.

AT-FS202SC/FS 4 SC 100 km (62 mi) RJ-45 100 m (328 ft)

1. Maximum distance for 100 Mbps optical datalinks is dependent on the following factors: type of optical fiber,

duplex mode of both end-nodes, and maximum optical loss budget for each of the optical fiber at the operating
optical wavelength.

2. Maximum distance can only be obtained when the UTP/STP cabling is installed and verified to TIA/EIA 568A

Commercial Building Telecommunications Cabling Standard.

Features

The AT-FS20x and AT-FS202SC/FSx Series Switches have the following
features:

❑ LEDs for unit and port status

❑ Auto MDI/MDI-X

❑ External AC/DC power adapters (North America, Continental Europe,

or United Kingdom)

❑ DIP switches for configuring the ports

❑ Half- or full-duplex operation on both ports

❑ RJ-45 twisted pair connector

❑ SC or ST fiber optic connector

❑ Data packet forwarding and filtering at full wire speed (10 Mbps to

100 Mbps, 100 Mbps to 100 Mbps, and 10 Mbps to 10 Mbps)
