Manufacturing process of optical cable

The invention discloses a manufacturing process of an optical cable. The manufacturing process comprises the following steps: 1) winding a water-blocking tape on the outer side of a cable core at intervals; (2) enabling the cable core to enter a paste coating device to be coated with ointment; (3) enabling the cable core to enter an extrusion molding device, and processing an outer sheath on the outer side of the cable core; and 4) cooling and drying the outer sheath, and then spraying an identification mark at the corresponding position of the outer sheath and the dry-type waterproof jacket. According to the application, the water-blocking tapes are arranged at intervals before the cable core is coated with the ointment, so that after the cable core is coated with the ointment, the sections where the water-blocking tapes are located basically have no ointment. During actual construction, the optical cable is cut off at the identification mark, at the moment, no ointment flows out of the section of the optical cable between the cable core and the outer sheath, and the optical cable is more convenient to construct.
