Thanks.

Hi Ryan!
I understand your predicament quite well. There is a note in Section 8.4.4.2 100Base-FX Receive of the data sheet describing this issue, as well as an FAQ that I have linked below.
Basically, this is a known issue with the DP83822. The link status won't change in fiber, in order to get the correct link status, a soft-reset must be performed (Set Reg 0x1F = 0x4000) before reading Register 0x1.
Regards,
Alvaro
