# Connection to SFP

## Question

Asked by youzin00 on 2013-11-18 in Ethernet Chips.

I use wiz5100 to support tcp/ip connection, but now have to provide SFP module interface for the new board.
I want just to add PHY-SFP between WIZ5100 and SFP module.
if it is possible, can you recommend the Phy-SFP interface solutions or others?

Thanks.
KS Yoo

Hi, youzin00.

I’m sorry, unfortunately, it is impossible. W5100 doesn’t support it.

Best regards.
