Operation

Status LEDs

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	(Fiber Link - Port 1)			On = Fiber port 1 is receiving a signal.
LK2	(Fiber Link - Port 2)			On = Fiber port 2 is receiving a signal.
PWR
LK1
	LK2	Port 1	Port 2

Link Pass-Through

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.

Note: Link losses will be automatically repaired by the converters.
