AT-FS237
Fast Ethernet Single Strand Fiber Media Converter
FAST ETHERNET SINGLE STRAND FIBER MEDIA CONVERTER
AT-FS237s13/1-xx
2-port single strand fiber media converter,
10/100TX (RJ-45) to 100FX (SC)
(1310nm TX/1310nm RX)
with 12vDC power supply and distances up to
15km
POINT-TO-POINT ACCESS
Designed to be used in pairs in a network topolo-
gy to provide point-to-point access, the AT-FS237
media converter is a 10/100Mbps copper to sin-
gle-mode fiber media converter capable of sending
and receiving on single strand fiber (1310nm).The
AT-FS237 converts 10/100TX (RJ-45) to 100FX
(SC) and can extend distances up to 15km. Easy to
install and requiring no software configuration, the
compact, rack-mountable AT-FS237 comes with a
choice of external power supplies. And, finally, both
ports feature full- and half-duplex operation.
AUTO MDI, MDI-X
The AT-FS237 media converter features automatic
MDI/ MDI-X.The 10/100TX (RJ-45) port deter-
mines the configuration of the ports on connected
device and then configures itself.This feature
enables users to use either crossover cables or
straight-through cables when connecting device to
the copper port.
SMART MISSING LINK™ (SML)
The Missing Link feature allows the ports on the
media converter to pass the Link status of their
connections to each other. When the media con-
verter detects a problem with a port—such as the
loss of connection to a node—it shuts down the
connection to the other port, thereby notifying the
node that the connection has been lost.The AT-
FS237 also features Smart Missing Link™ (SML)—
a feature that monitors network connections and
provides notification when network segments fail,
allowing network managers to quickly identify the
source and location of failed segments and
minimize downtime.

2. The recommended mimimum range is stated in all cases where the maximum
transmitter output power exceeds the receiver’s saturation level. This is to prevent
blinding or burning out of the optical receiver on the far-end mode.
3. Distance is calculated based on ideal situations without any other loss factor.
