Are you wanting hardened devices for an outside cabinet install (if it's
going outside then you'd better want hardened devices) or is this for an
internal environmentally-sound install? What's your definition of "long
distance"? 1800ft, 10km, 20km, 40km, 70, 80, 110? Assuming SMF, do you
need simplex or duplex?
Have you considered talking to a FTTx vendor? We use Occam here and
they make some cost-effective fiber products built with FTTx in mind.
I'm not sure how they compare price-wise with products you listed below
but it might be worth checking out.
