The first step: the step forming cable core: cable core comprises cable core body or comprises cable core body and be coated on the external sheath of cable core by extrusion molding; Get central reinforce member, include many fibre-optic many Loose tube, many outer gasket for packings, to be placed on parallel for many Loose tube outside central reinforce member or stranded around central reinforce member in the mode of one-way spiral or bidirectional screw, many outer gasket for packings are placed in the external series gap of adjacent Loose tube, form cable core body at many Loose tube and many outer gasket for packing outer cladding protective seams; Or get central reinforce member, include many fibre-optic many Loose tube, to be placed on parallel for many Loose tube outside central reinforce member or stranded around central reinforce member in the mode of one-way spiral or bidirectional screw, to form cable core bodies at many Loose tube outer cladding protective seams; Or get central reinforce member, include many Loose tube of plurality of ribbons, many outer gasket for packings, to be placed on parallel for many Loose tube outside central reinforce member or stranded around central reinforce member in the mode of one-way spiral or bidirectional screw, many outer gasket for packings are placed in the external series gap of adjacent Loose tube, form cable core body at many Loose tube and many outer gasket for packing outer cladding protective seams, in every root fibre ribbon, comprise many light transmitting fibers; Or get central reinforce member, include many Loose tube of plurality of ribbons, to be placed on parallel for many Loose tube outside central reinforce member or stranded around central reinforce member in the mode of one-way spiral or bidirectional screw, form cable core body at many Loose tube outer cladding protective seams, in every root fibre ribbon, comprise many light transmitting fibers;
Second step: coated non-metallic forms half-finished step: get non-metallic and carry out coated outside the cable core described in the first step by longitudinal coated mode and make cable core outside be closed formation semi-manufacture, described non-metallic by coating, be arranged in coating and arranged in parallel and to be not in contact with each other and axis is positioned at many of same plane increases parts and form; Or get non-metallic carry out coated outside the cable core described in the first step by longitudinal coated mode and make cable core outside be closed formation semi-manufacture, described non-metallic by coating, be arranged in coating and arranged in parallel and to be not in contact with each other and axis is positioned at multiple enhancing piece bores of same plane, and get many and increase parts and insert and strengthen in piece bores, only insert one in each enhancing piece bores and increase part, when increase part being inserted enhancing piece bores, the temperature of coating is made to remain in the scope of 50 ~ 80 DEG C;
3rd step: form the step of finished cable: the semi-manufacture in second step are extruded upper jacket layer namely form finished cable through the core rod hole of extruding machine outside semi-manufacture; Or the semi-manufacture in second step are extruded transition bed through the core rod hole of extruding machine outside semi-manufacture, then on transition bed, extrudes restrictive coating namely form finished cable; Or the semi-manufacture in second step are extruded transition bed through the core rod hole of extruding machine outside semi-manufacture, then extrudes external protection on transition bed, then on external protection, extrude restrictive coating namely form finished cable;
Wherein, the material of described external protection is nylon rodent-proof material, the material of central reinforce member is that glass fibre increases plastic bar, light transmitting fiber is G.652 optical fiber or G.653 optical fiber or G.654 optical fiber or G.655 optical fiber or G.657 optical fiber or OM1 optical fiber or OM2 optical fiber or OM3 optical fiber or energy transmission optical fibre, the material of Loose tube is polybutylene terephthalate or modified polypropene, the material of outer gasket for packing is tygon or polypropylene, the material of protective seam is polyester band or waterstop or nonwoven fabrics, the material of restrictive coating is Low Density Polyethylene or medium density polyethylene or high density polyethylene or flame-proof polyethylene or low smoke and zero halogen tygon, the material of sheath is Low Density Polyethylene or medium density polyethylene or high density polyethylene or flame-proof polyethylene or low smoke and zero halogen tygon, the material of transition bed is polyester band or waterstop, transition bed thickness be 0.1 ~ 0.5mm, increase part by weight, comprise following raw material: polyvinyl resin 20 ~ 30 parts, acrylic resin 8 ~ 15 parts, model are JF-31 or JF-33 or JF-35 or JF-C superhigh molecular weight polyethylene fibers 30 ~ 50 parts, length is 0.01mm ~ 1.2mm glass fiber yarn 20 ~ 40 parts, EVA hot-melt adhesive 5 ~ 10 parts.
In the present invention, protective seam and sheath mainly serve and block water and the effect of protecting against shock; Sheath separately also serves the effect of adjustment; for the non-metallic produced; because its length, width, height are determined, therefore, for the optical cable with different protective seam diameters; need different non-metallic; and be provided with sheath, because its thickness can flexible, therefore; wider non-metallic can be adopted, do not need buying in addition and customization.
Therefore, the present invention has following main beneficial effect: speed of production is produced sooner, more easily, product qualified rate is higher, cost is lower, equipment investment is less, and the versatility of non-metallic is stronger.
The present invention is not limited to above-mentioned preferred forms, and should be appreciated that design of the present invention can be implemented to use by other various forms, they drop in protection scope of the present invention equally.
