Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber cable incorporating different sized multiple stacks of optical fiber ribbons. SOLUTION: The stacks are composed of a central stack positioned at the nearly center within the passage of a jacket and peripheral stacks positioned radially around the central stack. The difference exists between the dimension of the central stack and the dimension of one or plural peripheral stacks. A buffer container individually incorporating the peripheral stacks is intertwined in the longitudinal direction around the central stack. Inner surfaces extending in the longitudinal direction are included in respective buffer containers, these inner surfaces extend around the passage extending in the longitudinal direction, and the passage is demarcated by these inner surfaces. Individual stacks are incorporated in the passage. The considerable parts in the periphery of respective peripheral stacks are surely bounded by respective inner surfaces which are meshed with these parts.

Abstract: PROBLEM TO BE SOLVED: To provide an optical module, including a stack for optical fiber ribbons in a buffer holder. SOLUTION: This optical module is rectangular. A sheath protects all side faces of a stack 32a. In some optical modules 30a, the stacks 32a can be moved relatively to the sheath, and optical fiber ribbons 34 can be moved relatively to each other. The sheath is sufficiently flexible so that optical fiber ribbons 34 can be slid in the transverse direction relative to each other. Consequently, the stack 32a and the sheath can be changed from non-oblique shapes to oblique shapes in the end face figure of the sheath. The stack 32a assumes a shape twisted in the lengthwise direction, and the sheath is hard enough to hold the stack 32a assuming this shape. The sheath has a thickness with its outside surface demarcating a rise corresponding to the twist of the stack 32a.
