How to implement serial-to-fiber optic Ethernet with WIZnet W5500?

Hello! I’m using W5500 to implement a serial to Ethernet converter, but I need to transmit over fiber optic cables. I will have a TX cable and a RX cable.

How can this be done since the output of W5500 is differential? Can you suggest a schematic?

Thank you!
