So, why not say "48 VDC" and leave it at that? If you add a polarity then
you also imply ground reference.

I'll confirm, Lumina is a floating ground.
We say -48VDC since that is the telco standard (and some of our other radios
are -48VDC only).

I thought all the SAF stuff was +48, but the CFIP Lumina FODU datasheet
says
-48? Is this the built-in DC-DC converter thing? I'm confused.
