Cisco ISR 4331 100base LX/LH SFP transceiver module Single Mode

[Ernesto1]

Team,

I have a Cisco ISR 4331 router and I need connect to a 100base LX/LH SFP transceiver module Single Mode, I saw there is 2 SFP 100base for this router  

GLC-FE-100BX-D
GLC-FE-100BX-U

Do you know which interface type BX10-U or BX10-D, is compatible with LX?

Thank you so much in advance

I don't think these SFPs are compatible with a standard SFP on the other end. The BX10-U and BX10-D use a single fiber for transmit and recieve. The U transmits at 1310nm and receives at 1550nm and the D transmits at 1550 nm and receives at 1310nm. So they are used on either side of a link.

According to this link the GLC-FE-100LX should work as long as you have a minimum IOS of 16.4.1 or 3.10.

That is a great information I will try to get a GLC-FE-100LX I am sure that I have one in somewhere, let me get it and I will replay with the results.

Again, thank you so much.
