In a greenfield build, cost difference for plant between PON and active

splitters.

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).

On the CO-side electronics, however... I think it's safe to say that you
can do GPON under $100/port.

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

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