For material water-proof material, regulation reinforcement material and material water-proof material laying tension are 1 ~ 1.5N；
（3）Light unit makes
Tight tube fiber or optical fiber micro-pipe pay off rack are got out, pay off rack tension force is adjusted, regulation tension force is 3.0-5.0N, interior
Sheath material uses low-smoke halogen-free flame-retardant sheath material；Inner sheath extrusion temperature is set, and temperature control is at 130-170 DEG C, by light list
The reinforcement material that first enhancement layer needs, through pipe or plsitive mold is squeezed, opens traction with material water-proof material, opens extrusion molding switch, adjusts
External diameter is saved to acceptability limit；Tight tube fiber or optical fiber micro-pipe are passed through into mould, extrusion molding inner sheath is cold twice through hot water storgae, cold rinse bank
But, through the upper disk of traction, light unit is made；
（4）Water blocking layer makes
Water blocking layer uses waterstop or water blocking yarn, and waterstop is used around packet mode using vertical packet mode parcel light unit, water blocking yarn
Wrap up light unit；
（5）Electric unit makes
Electric unit uses electronic isolation line or twisted-pair feeder；Loose tube pay-off frame tension force is adjusted, is 5N- by loose tube pay-off frame tension adjustment
10N, electric wire is placed on beam tube frame；
（6）Reinforcer makes
Reinforcer uses non-metal reinforcement member, and laying tension is set to 50 ~ 70N；
（7）Oversheath is produced
Oversheath uses polythene material, sets jacket material extrusion temperature, and extrusion temperature is controlled at 145~220 DEG C, selection
Install mould and extrusion molding speed, extrusion molding speed is 15~30 r/min, and external diameter is regulated, electric unit, light unit together with
The outer extrusion molding oversheath material of water blocking layer, forms oversheath, is cooled down twice through hot water storgae, cold rinse bank, hot water storgae temperature control 45~
60 DEG C, at 19~25 DEG C, through the upper disk of traction, high-definition multimedia transmission optoelectronic composite cable is made in cold rinse bank temperature control.
