If you choose to have CO-based splitters, you need to have MDF
for L1 unbundling, and 1:8 (or 1:4, 1:32 or whatever) optical
splitter module for PON, combination of which requires more
CO space and money than SS (single star) optical equipment (just
MDF).

Never ignore space and cost of optical splitters required only
for PON.

Note that the splitters cost even if they are located in field.
