(Lots) cheaper optics?

Dunno about current PA/SPAs, but I remember fairly well that the price
difference between a PA-A3-OC3MM and a PA-A3-OC3SMI was well over 
5000 EUR when we got the first couple of them, and that will buy you
some amount of single mode fiber installation later on...

Of course we had to get the single mode PA, because all the carriers
only did single mode... (which makes sense, at least from a spare part
handling view).
