Notes:
1. The RS0/RS1 PU/PD resistors are not populated.There are pull-down resistors built into the SFP28 modules that
select the lower bandwidth mode of the module.
2. BW selection is also available via I2C control. For this and additional information about the SFP28 module, see
SFF-8402 and SFF-8432 at the specification website [Ref 28].
