AT-FS238
2 port single strand fiber media converter,
10/100TX (RJ-45) to 100FX (SC),
(1310nm TX/1550nm RX) or (1550nm
TX/1310nm RX) with distances up to 40km
10/100TX (RJ-45) to 100FX (SC),
(1310nm TX/1550nm RX) or (1550nm
TX/1310nm RX) with distances up to 40km
Overview
The AT-FS238 media converter is a 10/100Mbps
copper to single-mode fiber media converter
which can send and receive on single strand
fiber (1310nm TX/1550nm RX) or (1550nm
TX/1310nm RX).These units are designed to be
used in pairs in a network topology to provide
point-to-point access.The AT-FS238 converts
10/100TX (RJ-45) to 100FX (SC) and will
transmit up to 40km on high quality fiber optic
cable. Both ports feature full and half-duplex
operation.The AT-FS238 is easy to install and
does not require software configuration or
management. Additionally, it can be used almost
anywhere due to its small physical size, choice of
external power supplies and options to be rack-
mounted.

Auto MDI/MDI-X
The AT-FS238 media converter features
automatic MDI/MDI-X.The 10/100TX (RJ-45)
port automatically determines the configuration
of the port on the device to which it is
connected and then configures itself
appropriately.This feature allows you to use
either crossover cables or straight-through cable
when connecting a device to the copper port.

MissingLink
TM
and Smart
MissingLink
TM
(SML)
The MissingLink feature allows the ports on the
media converter to pass the ‘Link’ status of their
connections to each other. When the media
converter detects a problem with one of the
ports, such as the loss of connection to a node,
it shuts down the connection to the other port,
thus notifying the node that the connection has
been lost.The AT-FS238 also features Smart
MissingLink (SML). This feature monitors
network connections and provides notification if
a network segment fails. This allows network
managers to quickly identify the source and
location of a failed segment and minimize
downtime.
