Uni - Tube Air - Blown Micro Optical Cable Production Extrusion Line
Uni-Tube Air-Blown Micro Optical Cable Production Extrusion Line
1.Description for Uni-Tube Air-Blown Micro Optical Cable:
Optical Fibers are housed in a loose tube that is made of high-modulus plastic and filled with tube filling compound. Aramid yarns are placed outside the loose tube as the strength member, then a sheath with grooves is extruded. This type of cable is particularly applicable to air-blowing constructions in access networks.
