AT-FS238
2 por t single strand fiber media
conver ter,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 conver ter is a 10/100Mbps
copper to single-mode fiber media conver ter
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 conver ts
10/100TX (RJ-45) to 100FX (SC) and will
transmit up to 40km on high quality fiber optic
cable. Both por ts 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 conver ter features
automatic MDI/MDI-X. The 10/100TX (RJ-45)
por t automatically determines the configuration
of the por t 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 por t.
Smart MissingLink
TM
(SML)
The MissingLink
TM
feature allows the por ts on
the media conver ter to pass the ‘Link’ status of
their connections to each other. When the
media conver ter detects a problem with one of
the por ts, such as the loss of connection to a
node, it shuts down the connection to the other
por t, thus notifying the node that the
connection has been lost. The AT-FS238 also
features Smar t 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.
