Ethernet 10-pin header to fiber optic SFP transceiver?

[krastatter]

We design our own carrier boards for use with MOD5234's and MOD54415's. At present we connect the MOD5234/MOD54415's RJ45 connector to an external Ethernet-to-fiber module. In the future, we want to integrate the fiber optic connection into our carrier board.

Is it possible design a carrier board that connects a module's 10-pin Ethernet header to a SFP cage?

First up, what type of fiber are you using? There's multiple different 100 base protocols, none of which, to my understanding are strictly compatible with feeding from the 100Base-TX PHY on the MOD5441X. So, unless the SFP has a PHY conversion or expects 100Base-TX, the notion is dead from the get go. That said, that may be how SFPs are designed, I've just never been able to dig much deeper than this.
