2 Port Fast Ethernet Single Strand Speed/Media Converting Switch
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
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
wer supplies and options to be rack-
nal po
exter mounted.

Smart MissingLinkTM(SML)
The MissingLinkTMfeature 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
thus notifying the node that the
t,
por 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.
