Abstract:
A method of making a fiber optic cable having a messenger wire and a core having at least one slot with at least one optical fiber therein, comprising the steps of:(a) pulling the messenger wire and the core through a melt cavity having a molten jacketing material therein;(b) defining a messenger section jacket and a core section jacket by coating the messenger wire and the core with said molten jacketing material;(c) monolithically forming a series of connecting webs made of said molten jacketing material during a web-forming mode;(d) forming longitudinal gaps between said connecting webs during a longitudinal gap-forming mode by switching between said web-forming and gap-forming modes; and(e) regulating the pressure of said molten jacketing material to minimize pressure fluctuations during the gap-forming mode.
