Dear

We try to change registers to set SFP+ work and change speed.

But I do not know how to set the registers

We control by I2C.

Please, check the attachment.

Hi,

The net names connected to OUTA+/- look like receiver connections, while the net names connected to OUTB+/- look like transmitter connections. I would verify the DS125DF111 is connected to the SFP+ module correctly.

The easiest way to determine register settings is by using the Sigcon Architect software GUI.

The tool and retimer profiles are free to download at the URL below.
