FPGA to SFP

I have designed Cyclone V based FPGA board. But i have connected with Normal IO instead of Transceiver IO. I need to clarify, whether this will work or not. I have attached schematic ...

This will depend on how fast you're hoping to operate the SFP module. At 1Gbps? Then no - it's not likely to work. If the SFP will run @ 400Mbps, and that's acceptable to you, then yes - you may be able to get it working.

Refer to Table 33: 'High-Speed I/O Specifications for Cyclone V Devices' - in the "cyclone v device datasheet (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/cyclone-v/cv_51002.pdf)" for the max differential data rates you can expect for 'normal' I/O.
