SFP fails to transmit data with a 10/100 Mediaconverter

I tried both SFP modules (single mode FO) s-53lc20d A with a 10/100 Media B and S-31DLC20D paired with a 10/100 media
I got the link up but i do not trasmit any packet
Is there any special configuration that i have to do te get data transmit?
