The optical cable is designed as a bundled tube layer stranded structure, mainly tube layer stranded and tube layer stranded. Structural features:
*R, glass reinforced fiber, serves as the central tension element and anti-folding element.
*B, polybutylene terephthalate is used as the bundle tube material. Optical fibers with appropriate excess length are inserted and filled with water-blocking fiber paste
.
*Aramid yarn, as a tensile strength component, the number of aramid yarns is designed according to the strength requirements, and by adjusting the torque-balanced aramid winding, it has extremely high tensile strength and stress-strain characteristics.
*Sheath, the inner sheath is made of black polyethylene, and the outer sheath is divided into ordinary polyethylene and trace-resistant polyethylene, corresponding to the space potential and working environment.
