In outside-plant environments, whether they are multi-building campuses or longer-haul communications networks, the initial installation and later re-configurations of fiber-optic systems present opportunities to either save or spend significant amounts of money. The efficient utilization of the pathways plays a central role in this economic equation. Enter pliable ribbon technology. This type of ribbon has separations between groups of fibers that allow a ribbon to be flexible and roll onto itself. This technology is the answer to wasted space in central tube cables. Pliable ribbon technology allows for packing densities within cables similar to that of loose single fibers.
