The optical unit just carries the laser , the receive photodiode matrix ,

Errr, I'm not getting this. The SF-P101N is a well-known Sanyo laser,
and available - even as a complete sub-deck - for just a few quid -
literally ...
You are slightly correct in there being more than one flavour. There are
in fact two. One has a 15 pin connector, and the other, a 16 pin. This
is always detailed where they are offered for sale, so there should be
no issue getting the right one.

In the meantime
It all seems mighty weird that you can progress flawlessly through the
test routines along with never any error statements but the unit does not
work.
Test routines pass byte info out on focus balance, focus gain,track
balance , track gain , focus offset , track offset,RFRP and a routine that
sums errors in a 2 second sample. Go into the auto adjust routine after
adjusting the power pot and the values change. I don't know what 100%
error figures for 2 seconds would be ,but readings about 023,000 one time
then adjust pot and then average about 035,000. So if 6 digits is 100%
then about 2 to 4 percent. What would a representative figure be for
dust,microscratches,scatter etc ?
Sanyo one in there and working all functions. So bulk standard cheapo with
no added Denon flavour it would seem.

Yep. I've replaced quite a few, and never found them to be anything
other than 'standard'. Did you get a whole sub-deck in the end, or just
a laser ?
