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.

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 fiber group closely connected by an easily removable buffer coating and a related optical fiber cable. SOLUTION: A buffer coating 36a is extended around a passage extended in the longitudinal direction for housing an optical fiber ribbon laminated object 32a and is provided with an inner surface, extended in the longitudinal direction for stipulating the passage. The inner surface is in close contact with the laminated object at a boundary, and the buffer coating 36a is removed easily from the laminated object 32a. Since the buffer coating 36a is constituted of a thin and easy-to-tear material, the buffer coating 36a is removed easily from the laminated object. Also, since the buffer coating 36a stipulates a weakened part extending in the longitudinal direction and the weakened part can be torn apart more easily than the remaining part of the buffer coating 36a, the buffering coating 36a is removed easily from the laminated object.

Abstract: PROBLEM TO BE SOLVED: To provide a package to be a buffer for a laminate by storing the laminate of optical fiber ribbons in a buffer coating, which has a relatively soft inner part and a relatively hard outer part. SOLUTION: This laminate 32a of optical fiber ribbons 34 is stored in a buffer coating 36a, which has a relatively soft inner part and a relatively hard outer part. The inner part has an inside surface, which is extended around a passage and defines the passage which passage stores the laminate 32a and is extended in the lengthwise direction. This inside surface is brought into close contact with the laminate 32a. The outer part is extended around the inner part, closely defined with the inner part and is brought into close contact with the inner part and has a modulus of elasticity higher than that of the inner part. The inner part has an outside surface, which is extended around the passage and is separated from the passage. The outer part has an inside surface which is extended around outside surface of the inner part, closely defined with respect to the outside surface, brought into close contact with the outside surface and is connected to the outside surface, and thus the buffer coating 36a has a multi layered structure.

Abstract: PROBLEM TO BE SOLVED: To facilitate the access to fibers in a central part when optical fiber ribbons are divided by allowing the fibers selected among the plural color coded optical fibers to have the strength of adhesion varying between fiber coating layers and a matrix. SOLUTION: The individual optical fibers 21 to 24 and 26 to 29 are coated with the colored layers and are then cured, and arrayed in the prescribed positions of the ribbon and are sealed into a matrix material 18. The number of the optical fibers included in respective sub-units and the number of the sub-units by which the ribbon is divided are determined. The adhesive power between the matrix of the first and second adjacent fibers and the adhesive layers is increased, by which the optical fiber ribbon which can be divided to the plural sub-units is obtained. The colored layers of the respective fibers contain peeling agents. The amounts of the peeling agents of the first and second fibers are decreased. The amounts of the peeling agents of the first and second fibers are preferably specified to about 15 to 40% of the amounts of the remaining peeling agents.

Abstract: A variable fiber count optical fiber cable core is disclosed. The cable core is intended for use as a part of an optical fiber cable, the optical fiber cable having an elongate cylindrical core tube formed about a longitudinal axis, and within which the cable core is received. The cable core comprises a stac k of a plurality of variable fiber count optical fiber units formed about the longitudinal axis of the core tube, and housed therein. The stack of the optical fiber units will comprise at least a first optical fiber unit having a first predetermined number of fibers therein, and at least a second optical fiber unit having a second predetermined number of optical fibers therein, where the first and second predetermined numbers of optical fibers differ from one another within the stack of optical fiber units. So constructed, the number of optic al fibers within selected ones of the stack of optical fiber units will be vari ed dependent on the position of the selected ones of the optical fiber units within the stack of optical fiber units, and so that the stack of optical fiber uni ts takes on the approximate shape of a cylindrical cable core within the cable core tube. Each of the optical fiber units comprised a first predetermined number of optical fibers sub-units joined together, each of the optical fiber sub-units being comprised of a second predetermined number of optical fibers, where both the first and second predetermined numbers of sub-units and optical fibers, respectively, comprise integers.
