Scott, I may have been unclear on this, sorry about that. A standard conduit will accept three or four inner ducts, depending on outside diameter of the conduit, and how tightly they want to squeeze. Each 1 1/4 inch inner duct, in turn, is capable of handling a fiber optic cable constructed for outdoor use. Sometimes multiple cables are fed through a single innerduct, but on the long hauls it's standard practice to limit it to one oversized cable per inner duct, ordinarily. The cables themselves differ in core acceptance (LEAF, zero-dispersion shifted, standard single mode, etc.) and may contain as many as three gross worth (432), as in the case of the Pirelli line, or greater number of strands. Many of the previous cables placed were limited to 48 or 96 strands, with some going with 144 or 288. The PR I referenced demonstrated that it was able to get four innerducts placed into a signle conduit (that was the breakthrough they were referring to), allowing three larger conduits to handle as many as 12 innerducts in total. They stated 12 conduits in this case when they meant 12 inner ducts. HTH, Frank Coluccio
