The SFMFF4040-100 optical line converter is designed to operate without user
intervention. Use the status LEDs to view the operation of the converter in the
network. 

PWR (Power)

On = Connection to external power.

LK1

On = Fiber port 1 is receiving a signal.

LK2

On = Fiber port 2 is receiving a signal.  

The Link Pass-Through feature allows the media converter to monitor both
fiber RX (receive) ports for loss of signal. In the event of an RX signal loss (1),
the media converter will automatically disable the TX (transmit) signal (2),
thus, “passing through” the link loss (3). The far-end device is automatically
notified of the link loss (4), which prevents the loss of valuable data
unknowingly transmitted over an invalid link.
