I've run into this more often the past year, as customers are ready to replace their cable/fiber plants, specifically regarding the decision between deploying pervasive single vs. multi-mode fiber. I know the bandwidth/distance limitations for SMF/MMF (all flavors), and understand the additional expense for SMF optics.
Having said all of that, I'm looking for any other reasons (to bring to the customer) regarding SMF vs. MMF. Specifically, if cost were NO object, would there be no reason to recommend SMF for all fiber installations, no matter the distance/BW requirements?
Thanks - as always, reference docs/links are always appreciated.
