I'm inclined to agree that when we are talking about unit numbers
between 10km >> 40km optics, the marginal price change of a few bucks
per optic (vs the human time to go and fix/groom/find/reduce optical
losses) is pretty minimal.
For that 1% of customers that finds their total cost significantly
impacted (vs, say the cost of the equipment these are going into,
etc).... would force 10% of us to have to engineer bypass cross-connect
panels with fewer physical connections (and spliced ones at that) to get
the job done.
Just my guess... but no one has really complained about 10km reach
optics being so expensive after the first 5 minutes they've been on the
Personally, I wish this much cost could be cut out of the 80/120km
optics market... but hey, no one is asking me.
