Check the fiber cable connection between the media
converter and the remote device. Check that the
distance between them does not exceed limits for
single mode (MC100FX-SC30) or multi mode fiber
(MC100FX-SC2).
Check for faulty cables.
Check what duplex mode the remote device supports
and then set DIP switch 2 (off for full-duplex and on for
half-duplex).
If Link Loss Forwarding is enabled (DIP switch 3 is on),
then check if the Ethernet link is down (thereby forcing
the fiber link down).
