I've been talking with a number of vendors about installing fiber in our manufacturing building. We've settled on a solution that calls for 1 MDF and 6 IDF cabinets, each with ethernet switches, but with a fiber backbone.
One vendor wants to do 6 strands of singlemode and 6 strands of OM4 multimode to each cabinet. Their pitch is that having both varieties in there gives me more flexibility and more options down the road with regard to equipment.
I'm not certain though - it almost seems that I'll end up using one and the other will just sit dark.
Anyone have any experience with this kind of thing?
