Cannot get fiber interface to show "up". Can I confirm SFP Module functionality?

I ordered an SFP module that should be compatible with my 200D. However, I cannot get the interface up. Note that this is my first time ever working with fiber. Most recently, I have tried setting the speed manually to 1000full, however this isn't working. Is there some way to "test" this SFP module? Or anything else I should try?

# config system interface

# edit dmz1

# show

"set speed 1000full"

# diag hardware deviceinfo nic dmz1

"status :down"

"Speed :10"

"Duplex :half"

# set speed 1000full

# show

"set speed 1000full"

# diag hardware deviceinfo nic dmz1

"status :down"

"Speed :10"

"Duplex :half"

p.s. This editor is frustrating.

I would think either a bad/wrong SFP or a bad slot.

Also I would try "get sys int transceiver dmz1" to see if the unit sees the SFP. If it's detected, it would show TX/RX optical level. If the numbers look normal, I would set a loopback with either dmz1 to dmz2 or a TX-RX loopback cable.

If it shows one way without a loopback, I would check the other end. Might need to call the vendor if that's on their end.

Then finally if none of above found the cause, I would open a ticket to get help from TAC.

FG200D # get sys int transceiver dmz1
ioctl SIOCETHTOOL.ETHTOOL_GMODULEINFO error(-1)
Interface dmz1 - Transceiver is not detected.

:(

I'll try putting it in the other slot, but any other ideas?

edit: Same result in dmz2. I guess I'll order a new transceiver.
