Abstract
A core for use in a slot type optical cable has one or more regularly disposed slots. One or more ribbon fibers are stacked into each of the slots, each of the ribbon fibers having a plurality of optical fibers. A tensile strength member is disposed at a center of the core. Each of the slots has a convex bottom surface with a predetermined curvature so that voids between the ribbon fiber at the bottom of the stack and top of the convex bottom surface in each of the slots are formed on both sides of the convex bottom surface. The convex bottom surface is provided with curvature whose radius is equal to or less than a distance from the center of the core to edges defined by the convex bottom surface meeting the pair of side surfaces in each of the slots.
