I am very curious as to why someone would do new deployments of MMF today. 
I know quite a few in the ISP business who has decided to go solely to SMF 
to try to cut down on number of spare parts and types of cables. Cost of 
cables and installation seems very similar.

Is there really an end user cost benefit with MMF today? Also, 
theoretically, will MMF survive the next leap in speed again, isn't it 
just a matter of time before everybody has to switch to SMF anyway?
