    • Disclosed is an apparatus for fabricating an optical fiber, which comprises a furnace for melting a sealed preform assembly to draw an uncoated optical fiber, a coater for coating the uncoated optical fiber, a capstan for drawing the optical fiber from the optical fiber preform by applying a drawing force, an adjoiner for holding a primary optical fiber preform inserted centrally into an overcladding tube with an equidistant space between the outer surface of the primary optical fiber preform and the inner surface of the overcladding tube, and a preform positioner for supporting the sealed preform assembly in a specified position with respect to the furnace. The adjoiner has passages that provide an inlet for receiving a flow of gas, a channel in which the flow of gas generates a reduced pressure region, and a suction tube for extending the reduced pressure region to the interior space of the overcladding tube, whereby fusing of the overcladding tube to the primary optical fiber preform is achieved during the drawing operation.

    • An apparatus for fabricating a metal coated optical fiber cable is disclosed. The apparatus includes a tape forming unit causing both side edges of a metal strip subjected to traction to abut against each other to form a metal tape, an optical fiber guide unit for guiding an optical fiber or an optical fiber bundle into the metal tape, a welding unit for welding abutment portions of the metal tape against each other, and a fastening unit surrounding the metal tape having the welded abutment portions in order to maintain a shape of the metal tape. The fastening unit is formed at an inner peripheral portion thereof, which makes contact with the metal tape, with a concave-convex section.
