Ray, I see we're talking to each other on different threads. This reminds me of the old one-liner that some of my geeky friends tried using during pickup attempts: "Pardon me, but didn't we go to different high schools together?" Re the strand count, there has been some movement on this front that most are not aware of unless they read Lightwave Magazine often, and very closely. Today, each innerduct within a conduit (of which there could be three or four per 4" conduit) which is now being placed contains three-to-six gross [144 * n] counts of fiber. Some, even more. I.e., the 1 7/8 inch o.d. innerduct could contain up to 864 strands tightly packed. I believe it was Pirelli who more recently came out with a 1,152 strand cable [1448] of the same overall outside dimensions, but I am not aware of MFNX's adopting it, yet. Maybe someone else could answer that. Multiply the numbers I gave by three innerducts per conduit, and you have your conduit-route capacity of 2,592 strands per route/conduit. The number of conduits which are placed in trenches along fiber routes varies anywhere from one or two to up to twelve or more, depending on anticipated traffic densities between terminus points. 864 strands per innerduct 3 innerducts per conduit = 2,592 strands/contuit. Multiply this by six conduits, eventually.... you see where this goes. Last year at this time MFN told me they were doing the 432's. That was two releases of densification ago. FWIW.
