Abstract:
A method for making an optical fiber cable, the method comprising the steps of:a) receiving a flow of molten plastic material with a core tube;b) splitting the flow of molten plastic material in the core tube;c) supplying the flows split in said step (b) to separated locations defined at annularly-spaced intervals in the core tube;d) molding the split flows of molten plastic material from the separated locations, between a surface of a die defining an aperture with at least one circular hole less than 2.0 mm in diameter, and an end portion of a core tube insert having an end portion extending into the aperture of the die; ande) advancing at least one optical fiber having a respective buffer and yarn layer, through an aperture defined in the core tube insert, the core tube and the die so that the molding of said step (d) forms a sheath about the yarn layer, the buffer and the optical fiber.
