Hi Anne,

DS250DF810/DS280DF810 does not support termination or generation of RS-FEC.
Data with RS-FEC can pass through the device.

Liang

Hi Liang,

Thanks for your feedback, and one more question as below,
If we use DS250DF810 retimer for 25Gb signals, does DS250DF810 Rx side have min eye mask requirement?

Hi Anne,

1. Post-equalized horizontal eye opening (HEO) > 0.4375 UI (note this is a register value of 14 in the device HEO register 0x27)
2. Post-equalized vertical eye opening (VEO) > 200 mV (note this is a register value of 64 in the device VEO register 0x28)

Regards

Liang
