Correction. Though I wrote 4000, it is a population and the number of subscribers are 1150. > For example, if drop cables of PON are 10m longer in average than > that of SS, it's total length is 40km, which is *SIGNIFICANT*. Total drop cable length is still 11.5km and is *SIGNIFICANT*. Note that when population density is lower, extra drop cable length will be longer that 10m is now a very humble estimation. As for equipment cost, for CO PON 92000 KJPY/1150 SS 182000 KJPY/3100 and for CP PON 33200 KJPY/1150 SS 84600 KJPY/3100 not so different but SS is a little more inexpensive. Masataka Ohta
