Re: Optical Connectors
I agree with the second part from Tad, as I outlined when I suggested we refer to
other standards groups. But the first part I disagree with. Had we known back
then that SFF components would be so popular, I don't believe the SC would be
listed, or the only one listed. I reckon my question was "is there a solution
today that beter suits us then the SC?" I just don't buy the arguement "If it
ain't broke, don't fix it" for this case. I really thing we should be looking at
the SFF packaging right off the bat.
