Abstract: This application belongs to the field of optical cables and provides a reinforced protection micro-bunched cable and a manufacturing process thereof. The reinforced protection micro-bunched cable includes reinforced protection micro-bunched tubes; the outer surface of the reinforced protection micro-bunched tube is arranged with bumps and there is a gap between bumps. The thickness of the micro-bunched tube wall at the gap between the bumps is still small, and the bump material is softer than the tube body material. The thickness of the micro-bunched tube wall at the gap between the bumps is still small, which can meet the construction requirements of easiness for stripping; the bump can effectively buffer the external force; further, the added bumps can increase the longitudinal tensile properties of the whole tube, and the tube was not easy to be broken under tension.

The first buffer layer is a high elastic polymer material layer, and a Shore hardness of the first buffer layer is 45HA-85HA, a tensile strength of the first buffer layer is greater than or equal to 10 MPA, a breaking elongation of first buffer layer is 200%-600%, and a compression permanent deformation rate of the first buffer layer is less than or equal to 30%.

Abstract: A unidirectional stranded micro-bundle optical cable and a manufacturing process thereof, where the unidirectional stranded micro-bundle optical cable provided by the present disclosure includes micro-bundle tubes, a reinforcing layer, a water-blocking tape and an outer sheath; a first water-blocking yarn is arranged between the micro-bundle tubes, a tearing rope is arranged in the water-blocking tape, and a reinforcing member is arranged in the outer sheath; the micro-bundle tubes adopt a spiral stranding with a stranding mode of unidirectional stranding and a stranding pitch of 800 mm to 900 mm; the reinforcing layer adopts a spiral stranding with a stranding mode of unidirectional stranding and a stranding pitch of 600 mm to 800 mm; a stranding direction of the micro-bundle tube is opposite to a stranding direction of the reinforcing layer.

Abstract: Disclosed are an overhead ribbon cable, a manufacturing method, and a manufacturing system for the overhead ribbon cable. The overhead ribbon cable includes an optical fiber ribbon array (10). The optical fiber ribbon array (10) includes a plurality of optical fiber ribbons (11) arranged in an array. A surface of the optical fiber ribbon array (10) is wrapped sequentially with a water-blocking assembly and an outer protection layer (50). The water-blocking assembly includes a water-blocking sealing layer (20) formed by heating and curing a sealant. The water-blocking sealing layer (20) wraps the surface of the optical fiber ribbon array (10) in an axial direction of the optical fiber ribbon array (10) and fills a gap between two adjacent optical fiber ribbons (11). The overhead ribbon cable has improved splicing efficiency, and is clean and environmentally friendly.
