Benefit of FM Rx Technology
Subscriber distances based on 3000+ nodes from three major markets
 FM approach reduces Headend optics & rack unit requirement by 50% for
approximately the same outside plant distance as AM
 FM approach enables further reach & more splits (as high as 1:128)
PON Distance (km)
Note: Four bonded 64 QAM 6.4MHz upstream channel loading, all OSP assumptions are constant between split ratios and Rx technology, 1 GHz downstream loading with 48dB CNR
