No, SS is cheaper than PON without exception. If the initial density of subscribers is high, SS is fine. If it is not, initially, most electric equipment, OE port, fibers, splitters and a large closures containing the splitters of PON can not be shared by two or more subscribers, which means PON incurs much more material and labor cost for each initial subscriber than SS.
