100 base SX wan link on Cisco 1941

[batrajayant]

We have a wan link delivered on 100 Base SX  fiber .Please note it is 100 base sx and not 1000 base

The Router I have is a cisco 1941

I have added these part codes to support this WAN link but the link is not coming up

I have been told that SMD is 1000 speed while my WAN is 100 base sx.Am I doing something wrong.DO I need some other hardware

Quantity	Part Numbers	Product Description
1	EHWIC-1GE-SFP-CU	EHWIC 1 port dual mode SFP(100M/1G) or GE(10M/100M/1G)
1	GLC-LH-SMD	1000BASE-LX/LH SFP transceiver module, MMF/SMF, 1310nm, DOM

That is a "long haul" SFP, so that definitely wont be the one.  Here is the compatibility chart:

Search for "EHWIC-1GE-SFP-CU".  I think what you need is GLC-GE-100FX.
