Rather simple using cut and paste of 38.11.3 (duplex SC only) or by adding
to the above following my recommendations supported by Paul, Rich, Schelto,
Joel and few other: "When high density is an important consideration then
Small Form Factor connector designs that meet the dimensions and interface
specifications of IEC 61754-18, IEC 61754-19 and IEC 61754-20 outlined in an
Informative Annex XX are recommended." This would also be in line with ISO

I believe that you may have personal preferences regarding particular style
and by way of the same example please take a note that IEC 793-2 does cover
50/125, 62.6/125 MMFs in 850 and 1310 nm windows with multiplication of
bandwidth cells in four different categories (A1 - A4). The fifth, category
B, covers SMF.
As you can see the matrix is rather large.
